Faculty  Abstracts

Dennis Alexander
Electrical Engineering
dalexander1@unl.edu

Dr. Alexander’s research expertise is in the area of nanotechnology and ultra-fast laser beam propagation and interaction with matter.  He recently published a paper in Optics letters describing the operation of an all optical diode based on CdSe nanoparticles.  The University has a patent pending on this discovery.  This research and patent promises to revolutionize the fiber optical communications switching speed.  The Office of Naval Research (ONR), DARPA, and Army Research Office (ARO) fund his research on the transport of ultra short pulses (single cycle of light) through the atmosphere and through ocean water.  This research is related to the increasing interest in higher speed communications through the atmosphere and in the ocean.  Dr. Alexander is funded by an ARO MURI to investigate the fundamental process in laser induced breakdown spectroscopy (FLIBS) used to detect biological and chemical warfare agents.  The University has the patent on femtosecond FLIBS.  In addition, Dr. Alexander’s research has many applications to sensors.  A new thrust of his research is to apply these techniques for monitoring the safety of bridge and building infrastructures.  Dr. Alexander has over 10 patents and 3 pending patents.

 

Dee Ann Allison
Libraries
dallison1@unl.edu

My area of expertise is in library technology.  My main area of research is the analysis of database searching.  We generally believe that databases need controlled vocabulary (metadata) to be useful.  However research is increasingly indicating that most people don't use the terms in the controlled vocabulary for their searches.  I am interested in why this is occurring.  My research includes analyzing the ways people approach searching for information that differs from one discipline to another and the psychology of how people do searches.  I want to explore how technology can be adapted to better fit the searching practices of people.  

 

Peter Angeletti
Biological Sciences
pangeletti2@unl.edu

My research is focused on three main topics relating to sexually transmitted Human papillomaviruses (HPVs). The first area of emphasis is in the analysis of cis and trans-acting signals required for stable replication of HPVs.  A second area under study is the specific packaging requirements of HPVs.  In both of these studies, we make of use of a novel and convenient yeast system we have developed to model HPV functions and to identify cellular factors involved.  A final area of emerging interest for the lab is the analysis of HPVs in HIV positive patients in Zambia, Africa.  In these studies we will determine the extent to which HIV influences the rate of HPV infection and the rate of progression of HPV lesions to cancer.

 

David D. Baltensperger

bbarker@unl.edu

My primary research areas of expertise or interest are instructional technology and informal science- technology programs for youth development.  Recently, I have been exploring the effectiveness of using robotics to teach science, technology, engineering and mathematics (STEM) concepts in afterschool programs.  

Paul Barnes
Piano
pbarnes2@unl.edu

Hailed by the American Record Guide as "a magnificent pianist," the San Francisco Chronicle as “ferociously virtuosic” and “a riveting and sensitive player” by the Indianapolis Star, pianist Paul Barnes has been featured three times on NPR’s Performance Today.  He was featured on the November 2004 cover of Clavier Magazine and has recently performed in Jerusalem, Moscow, St. Petersburg, Greece, Serbia, Seoul, Vienna, Budapest and in major cities throughout the US.

Barnes gave the world premier performance of Philip Glass’s Piano Concerto No. 2 (After Lewis and Clark) in September of 2004.   The Omaha World Herald praised Barnes playing for his “driving intensity and exhilaration.”  Barnes also performed the concerto at the prestigious Cabrillo Festival of Contemporary Music with conductor Marin Alsop.  Barnes recorded the concerto in September of 2005 with the Northwest Chamber Orchestra.  The recording will be released by Orange Mountain Music in September of 2006.
Recently elected to the national board of the American Liszt Society, Barnes hosted the 2005 ALS festival at the University of Nebraska Lincoln from April 14-16, 2005.  The festival's theme was Heaven on Earth: Exploring the Sacred in Music.  Barnes also serves as head chanter at Annunciation Greek Orthodox Church in Lincoln and is Associate Professor and Co-chair of Piano at the University of Nebraska-Lincoln School of Music.  He teaches during the summer at the Bösendorfer International Piano Academy in Vienna and also coaches the students of Menahem Pressler, Barnes' own teacher, at Indiana University. 

Donald Becker
Biochemisty
dbecker3@unl.edu

My research focuses on structure-function studies of enzymes involved in proline metabolism, in particular, the multifunctional proline utilization A (PutA) protein from Gram-negative bacteria.  PutA is a flavoenzyme that uniquely combines proline catabolic and transcriptional regulatory activities within a single polypeptide. My group has uncovered a novel redox mechanism by which PutA transforms from a DNA-binding transcriptional repressor into a membrane-bound proline catabolic enzyme.  This work is
providing insights into metabolism-linked transcriptional regulation and how multifunctional proteins coordinate diverse functions. We are also investigating how proline metabolism impacts redox-linked processes in eukaryotes. The key proline catabolic enzyme, mitochondrial praline dehydrogenase, plays an important role in p53-mediated apoptosis by generating proline-dependent superoxide. Paradoxically, proline also protects cells against oxidative damage by scavenging singlet oxygen. We seek to elucidate the molecular, genetic, and chemical mechanisms by which proline metabolism helps regulate cell growth via modulation of reactive oxygen species.

 


John Bernthal
Special Education & Communications Disorders
jbernthal1@unl.edu

I am interested in children with phonological disorders and the effects of such disorders on literacy.

Christian Binek
Physics & Astronomy
cbinek2@unl.edu

My research activities take place in the framework of experimental solid state physics focusing on magnetic heterostructures, spintronics and fundamental aspects in thermodynamics and statistical mechanics. My group is specialized in the method of molecular beam epitaxial (MBE) growth. This modern ultra high vacuum growth method enables manufacturing of layered magnetic thin film structures. Growth conditions are controlled down to the atomic scale, which in turn enables fabrication of new and potentially useful artificially designed heterosystems. Special emphasis is laid on the fabrication of novel spintronics devices combining memory and logical functions. Their functionality is based on the electric control of the interface magnetization in exchange bias heterosystems using MBE growth of magnetoelectric/ferromagnetic exchange coupled thin films. Recently we focused on the training of the exchange bias effect and developed its theoretical thermodynamic description.
In addition, fundamental aspects of thermodynamics in artificial magnetic superstructures are explored. This includes the control of interlayer exchange in antiferromagnetic superlattices by temperature, magnetic and electric fields. Fundamental aspects of thermodynamics are also studied in magnetic nanoparticle ensembles.  With the help of magnetometry and magneto-optical methods we study non-extensive behavior in magnetic nanoparticles systems governed by dipolar long range interaction.
My research activities are supported by the Nebraska Center for Materials and Nanoscience, MRSEC Quantum and Spin Phenomena in Nanomagnetic Structures and NSF through the Career award DMR-0547938.

Ron Bonnstetter
Teaching, Learning & Teacher Education
rbonnstetter1@unl.edu
Dr. Bonnstetter is Professor of Science Education at the University of Nebraska - Lincoln. His research focus includes science education reform, questioning skill development, program evaluation, personal attribute identification, interaction analysis and teaching effectiveness. As a result of these interests, Dr. Bonnstetter has served as outside evaluator as well as PI on numerous projects totaling over $14 million, including:  Tech-Know (7-12 technology education material development), SESE (Search for Excellence in Science Education), POLARIS & CAPS,  (Alaska Science reform projects), Inspiring Inquiry (with several UNL Ed Psych faculty) , VisTE (Scientific Visualization in Technology Education), NANO (computer gaming to teach Cell metabolism) Laboratory Earth (with Dr. Dave Gosselin) and several ongoing projects involving personal attribute identification.
My interests are the history of science and technology from 1500 to the present. I'm above all interested in how science and technology interact with one another, as well as with the economy, culture, politics, and society at large. My published work has concentrated on the history  of physics in Germany and America during the 19th and early 20th centuries. My first book, An Institute for an Empire: The Physikalisch-Technische Reichsanstalt , 1871-1918I, concerned the rise of quantum physics at the world's first institute devoted to metrology, the institutionalization of science, and the interactions of science and technology during that era, including their importance for the state and society. Another book,Science at the American Frontier: A Biography of DeWitt Bristol Brace (co-authored with M. Eugene Rudd), was much concerned with the establishment of science here at the University of Nebraska between 1880 and 1905, and how Brace drew on his educational experiences in Boston, Baltimore, and Berlin to establish physics in Lincoln. I'm currently writing a full-scale biography of Hermann von Helmholtz (1821-94), who was widely considered to be one of the world's foremost physiologists and physicists (among other things) of his day, and one of science's leading public spokesmen. When I complete my biography, I intend to turn my attention full-time to an historical analysis of the relations of science, technology, and the economy in the
making of the modern world.

Raymond Chollet
Biochemistry
rchollet1@unl.edu

Dr. Raymond Chollet is a senior faculty member and plant biochemist in UNL’s Department of Biochemistry and campus-wide Center for Plant Science Innovation (PSI). His laboratory has had a long-standing, basic research interest in primary metabolic enzymes in plants, especially related to their (i) post-translational covalent modification by reversible protein phosphorylation, and (ii) protein structure-function relationships. Areas of most recent investigation have focused on phosphoenolpyruvate carboxylase (PEPC) and pyruvate, phosphate dikinase (PPDK), two “target” enzymes previously discovered by his group to undergo regulatory seryl- or threonyl-phosphorylation, respectively, in intact, CO2-fixing green leaves and/or N2-fixing legume root nodules. Their varied experimental approaches to these two metabolic enzymes, and the requisite protein-kinases and protein-phosphatases, have exploited the modern tools of molecular and structural biology, plant transformation, enzymology, protein chemistry, and immunology. These efforts have benefited immensely from numerous research collaborations within UNL and in France, Argentina, and elsewhere in the U.S. Additional details of his NSF/Metabolic Biochemistry-funded research program  can be found at http://psiweb.unl.edu/faculty.php?id=faculty4

In his work in Astroparticle Physics he is a member of the Underground Neutrino Observatory (UNO), working to develop NSF's Deep Underground Science and Engineering Laboratory (DUSEL). In Cosmic Ray Physics he is co-PI of Nebraska's Cosmic Ray Observatory Project, an outreach effort establishing a network of student-built detectors at high schools across the state. His work in High Speed Real-time Computing focuses on MHz events generating output >1/4Mb, which can only be selectively written at 45Hz, requiring microsec-msec decisions. In Supersymmetric searches he is using SUSY models to theorize additional (as yet unobserved) particles, considered prime dark matter candidates by astrophysicists.

Patricia Cox Crews
Textiles
pcrews@unl.edu

My research interests are focused in two primary areas.  First, the conservation of museum and heirloom textiles, specifically by examining the light and heat ageing properties of various materials, including textile adhesives, inks and dyes.  And, secondly, quilt studies – the study of quilts to gain insights into the lives of women and thereby advance understanding of women’s contributions to American society.   I am interested in object-based, as well as documentary research, that leads to greater appreciation of American quilts, as well as other forms of textile arts, because both have traditionally been undervalued, understudied and under represented in museum collections and scholarly discourse. 

Mohamed F. Dahab

Stephen DiMagno
Chemistry
sdimagno1@unl.edu

Chemical catalysis and organofluorine chemistry are the two main areas of my research program. In the catalysis arena the research focus is the selective oxidation of hydrocarbons, alcohols, hydrogen, and carbon monoxide. These fundamental processes are essential to the efficient production of energy from biomass. Three catalysis problems currently under investigation in our laboratories are 1) direct production of hydrogen from alcohols and alkanes (reforming) to generate hydrogen, 2) selective oxidation of carbon monoxide in the presence of hydrogen to generate clean H2 for fuel cell applications, and 3) simplified methods for biodiesel conversion. 
In organofluorine area we are interested in new preparative methods for the introduction of fluorine into organic compounds, and the physical properties of fluorinated pharmaceuticals. While there are less than 15 identified naturally-occurring organofluorined compounds, one third of all currently marketed agrochemicals and pharmaceuticals contain at least one fluorine atom. Despite the technological importance of fluorinated compounds, there are no “gold standard” synthetic methods to carry out fluorine substitution.  We have developed straightforward synthetic techniques that generate anhydrous fluoride reagents in aprotic solvents.  These reagents have proven useful for the rapid, late-stage introduction of fluorine. Current studies examine the fundamental properties of these reagents, and their usefulness in the preparation of PET radiotracers for biological imaging.

Larry L. Dlugosh
Educational Administration
ldlugosh1@unl.edu

My particular area of research is focused on the preparation and credentialing of leaders for P-12 (public) education and the changing environments in which educational leaders practice.  I have contributed chapters to books that profile the practices of exemplary educational leaders and have co-authored a textbook for the preparation of school superintendents.  
Leadership preparation for school leaders has been slow to change during the past 10 years.  Public education is under extreme scrutiny by parents, taxpayers, scholars, and state and federal governments.  The context in which public elementary and secondary schools has changed remarkably in the past 10 years, however, leadership preparation programs have generally not reflected the majority of the changes.

Research is necessary to assess how changing political, technological, economic, and cultural environments are related to the preparation of school principals and superintendents as they encounter high student mobility, decreases in state and federal funding, program accountability, and student learning requirements for global citizenship.
The educational preparation of successful school administrators must be studied; should agencies other than Colleges of Education be given authority to prepare school leaders who will be certificated by the state or should they be certificated at all? 

Stephen Ducharme
Physics & Astronomy
sducharme1@unl.edu

My research group focuses on the physics and applications of ferroelectricity at the nanoscale through the study of ferroelectric polymer crystals grown by Langmuir-Blodgett molecular layer deposition and by self-assembly. The fundamental studies include the phenomenology of nanoscale ferroelectricity and the design of new ferroelectric polymers. Applied studies include nonvolatile ferroelectric memories, high-energy-density capacitors for portable power and load-leveling, inexpensive high-performance infrared imaging arrays for night vision and heat imaging, and nanofluidic circuitry.
My interests in math and science education focus on the development and integration of proven Interactive-Engagement methods for large-enrollment introductory classes in the physical sciences. Current projects include the use and updating of Peer Instruction (using personal response systems that are proliferating at UNL), Group Problem Solving, and online exercises and assessment.

M. Cenk Gursoy
Electrical Engineering
mgursoy2@unl.edu

My research interests lie in the areas of mobile wireless communications, wireless networks, information theory, and signal processing. The two key characteristics of wireless communications that greatly affect system design and performance are 1) the time-varying nature of channel conditions and 2) limited energy resources. I address these challenges by studying energy-efficient communication methods under channel uncertainty. This study analyzes energy-efficient transmission schemes, channel
estimation methods, and energy expended to transmit one bit of data.
I am also interested in the analysis of ultimate performance limits of wireless systems through the application of information-theoretic tools such as channel capacity, error exponents, and cutoff rates. Another line of my research focuses on wireless networks. More specifically, I study the effects of resource and latency constraints, mobility, and node cooperation on the performance of wireless ad hoc and sensor networks.

Gary Hein
Entomology
ghein1@unl.edu
           
The major goal of my research is to develop improved insect management strategies for arthropod pests of small grains and specialty crops grown in the Nebraska Panhandle while reducing the overall impact of management tactics on the environment.  Emphasis is on the biology and ecology of the wheat curl mite (Aceria tosichella) and epidemiology of its two vectored viruses, development of virus resistant wheat cultivars, and mite-virus transmission relationships.  All of these projects are interdisciplinary efforts that involve multiple individuals.  One new project will be looking at using remote sensing to spatially define virus spread in the field so as to develop a model of mite movement and subsequent virus spread.  Other efforts are underway to use genetic techniques to characterize populations of pest species to understand host and plant resistance issues related to their management.

 

Tiffany Heng-Moss
Entomology
thengmoss2@unl.edu

My interests in teaching and outreach include development of state-of-the-art educational programs for undergraduate/graduate students and K-12 educators and their students. The following are examples of three educational programs:

  1. Development of Insect Biology for distance delivery to high school students for concurrent credit.  This course was the first concurrent credit course offered by the University of Nebraska and represents an innovative approach for UNL to be proactive in recruiting students. Insect Biology serves as a model for other departments and colleges at UNL along with other institutions planning to offer introductory courses to high school students for college credit. 
  • Bug Bash is a youth outreach event to introduce young learners to the fascinating world of insects.  A key element of Bug Bash has been a teaching-and-learning pyramid, which means that entomology faculty and graduate students train high school students and their teachers, who, in turn, present the information to fourth-grade students.
  • Our Zoo to YOU is an outreach education program sponsored by Lincoln’s Folsom Children’s Zoo, the Department of Entomology, the Center for Curriculum & Instruction, and Nebraska schools.  This program provides the instructional materials for student-designed investigations that require students to observe the characteristics of animals, how they respond to their environment, how the animals’ behavior is adapted to best suit their needs, and what special characteristics are present in each class of animals. 

John Hibbing

Christy A. Horn
Educational Psychology and NU Compliance Officer
chorn@nebraska.edu

I have been doing grant funded research for 20 years now.  My research has been primarily funded by the US Department of Education although I have worked on some NSF grants. My research agenda revolves around three primary issues; 1) the impact of technology on learning, 2) student engagement in learning especially in the sciences, and 3) the use of technology to accommodate students with disabilities in the classroom environment.  I have worked on a number of projects investigating how to improve teaching and learning in the sciences in both the postsecondary and K-12 environment.  My primary interest is in creating environments through the use of technology and web-based ancillaries that provide all students the opportunity to achieve their potential.

Kenneth (Ken) G. Hubbard
School of Natural Resources
khubbard1@unl.edu

I am interested in the calibration and performance of weather sensors, the microclimate experienced by sensors, data homogeneity issues, and in the quality control of data from networks.  I helped create and now manage a network of 59 automated weather stations in Nebraska that collect data on air temperature, humidity, soil temperature, wind speed, direction, solar radiation, precipitation and soil moisture.  I have been working with a team to determine the relative importance of attitude, social norm, perceived behavioral control and financial capability on the intentions of agricultural producers to use weather data and forecasts in decision making.  Other team efforts are underway to develop new weather-related drought products.  I have also applied energy balance and water balance techniques to determine the role played by evapotranspiration and soil water in ecosystems. I am examining the role of land use and changes in land use on the dynamics of the surface water and energy budget and the associated contribution to climate change.  I have recently been working with a team to determine the potential for agricultural producers to contribute to carbon sequestration.

 

John Janovy

jjanovy1@unl.edu

 My students and I study the ecology of parasitism (the most common way of life on Earth), with particular focus on the movement of parasitic organisms through ecosystems, the contribution of evolved life histories to population and community dynamics, and the role that host specifity plays in providing avenues for and constraints on parasite evolution.  Our study organisms are protozoa, flatworms, and roundworms, and we use systems involving mainly insects, small fish, and amphibia as hosts.  In practice, our work ranges from taxonomic to theoretical, and involves field work, experimental infections, molecular phylogenetics, and the maintenance of highly diverse menageries, usually in combination.

Carolyn Johnsen
College of Journalism and Mass Communications
cjohnsen2@unl.edu

In my college, “research” for the News-Editorial faculty most often involves publishing articles written in a journalistic style for a general readership.    I’m interested in two main paths of research: Exploring the environmental impacts of agriculture in Nebraska, including impacts on water quantity and quality; and  Developing methods and opportunities to help scientists and journalists write clearly and engagingly about science.   I also seek to develop links between scientists and journalists in communicating about science to the general public.

Elizabeth G. Jones
Civil Engineering
ejones1@unl.edu

Dr. Jones’ area of expertise is transportation systems analysis with emphasis in the areas of traffic flow theory, intelligent transportation systems and traffic signal control.  In the area of traffic flow theory, she has validated an extension of the two-fluid model of traffic that proves that this model is scalable and can be used to quantify the quality of traffic for an urban network as well as for arterial streets.  In the area of intelligent transportation systems, Dr. Jones is currently working on two projects.  One is to develop a statewide transportation data archive for Nebraska that will include multimedia data in addition to traditional transportation data.  The other current project in ITS is related to intelligent highway-railroad grade crossings.  The objective of the grade crossing work is to develop a robust signal preemption system for controlling highway traffic at both actively and passively controlled grade crossings using multiple vehicle detection sensors placed off of the railroad right-of-way.

Stephen Ragsdale
Biochemistry
sragsdale1@unl.edu

Ragsdale's NIH, DOE, and NSF funded research focuses on the biochemistry of metal ions in enzymes and on the basic mechanisms by which microbes metabolize toxic compounds and energy-rich gases. This latter project includes methanogens, which use hydrogen gas and carbon dioxide to make methane or natural gas, and acetogenic bacteria, which can generate hydrogen gas or utilize H2 and carbon dioxide to make acetic acid. While acetogens have a wide substrate range, methanogens can utilize a very narrow range of compounds for methane generation. The enzymes responsible for catalyzing these transformations are isolated and studied using a variety of biological, biophysical, and chemical techniques to uncover their mechanism.  The crucial and rate-limiting enzymes involved in these transformations are currently under study and include hydrogenases (catalyze the utilization and generation of hydrogen), methyl-CoM reductase (catalyzes the final step in methane production), carbon monoxide dehydrogenase (catalyze the utilization and generation of carbon monoxide and the interconversion of carbon monoxide and carbon dioxide). Future research plans would be aimed at attempting to genetically altering the physiology of methanogens to expand the range of substrates that they can utilize for conversion to methane. We also plan to study what controls the rate of methane formation in methanogens growing under different conditions (in single cultures and in natural consortia) to develop more robust ways to convert biomass to methane.

Marilynn Schnepf
Nutrition & Health Sciences
mschnepf1@unl.edu

The focus of my research is in the area of prebiotics specifically the study of the functional and nutritional properties of fructooligosaccharides(FOS).  Inulin, a type of FOS, is extracted commercially from chicory which is being grown in western Nebraska. Intestinal enzymes do not have the ability to digest inulin so it reaches the colon intact where it is fermented by colonic bacteria, especially bifidobacteria.  This fermentation results in numerous health benefits to the host.  We have studied the sensory, functional and nutritional properties of inulin compounds with various chain lengths.  Studies using long and short chain inulin added to yogurt showed several beneficial properties. Less syneresis was found with longer chain length inulin and sensory panelists found the yogurts with inulin to be more smooth and thick than the control.  Recent human studies were conducted to determine the effect of consumption of 20 grams of either short chained or long chained inulin on the growth of bifidobacteria. Gastrointestinal tolerance was also determined.  In most subjects bifidobacteria counts did increase with both types of inulin.  Most subjects did report changes in gastrointestinal function.

Jim Van Etten
Plant Pathology
jvanetten1@unl.edu

For the past 25 years my lab has focused on the isolation and  characterization of large viruses that infect algae. These viruses exist in fresh water from all over the world with natural titers as high as 100,000 infectious particles per ml. The algal viruses are among the largest viruses discovered, containing up to 400 protein-encoding genes. Thebiological functions of about 40% of the virus-encoded proteins are known. Many of these proteins are unexpected and have not been found in viruses previously.  The algal viruses also contain other properties that are more characteristic of cellular organisms including introns and inteins.  Accumulating evidence suggests these viruses have a long evolutionary history, possibly dating back to more than 2 billion years.  We have a wide range of projects dealing with these viruses, ranging from basic molecular biology to ecological studies. Current projects include: i) Identification of all virus-encoded
proteins packaged in the virion.  ii) Transcriptional analysis of viral genes during growth by microarray analysis.  iii) Sequencing of several more algal viruses.  iv) Sequencing of the algal host by the Department of Energy.  v) Characterization of newly discovered virus gene products including an aquaglyceroporin, a DNA primase, and a histone
dimethyltransferase.

Judy Walker
Mathematics
jwalker7@unl.edu

My research is in the area of algebraic coding theory.  Whenever information is transmitted across a channel, errors are bound to occur. The goal of coding theory is to find efficient ways of adding redundancy to the data so that these errors can be corrected.  Algebraic coding theory seeks to do this via algebraic, as opposed to random, methods.
Most recently, I have been studying the class of low density parity check (LDPC) codes.  LDPC codes come equipped with an extremely efficient decoding algorithm which operates on a bipartite graph associated to the code and which corrects, with high probability, many errors.   The efficiency of this algorithm is due to the fact that it operates locally on the graph, but this fact also leads to the algorithm's greatest
weakness: it is non-optimal.  My research seeks a better understanding of this non-optimality.

Daniel Wheeler
Ag Leadership, Education and Communication
dwheeler1@unl.edu

My research interests are particularly in the area of leadership and change in organizations and communities. My specific area is servant leadership which at its core suggests that an interest in serving is a pre-requisite to leading. This is an area of leadership in which practice is ahead of research partly because of a lack of a valid and reliable instrument to measure it. My colleague, Jay Barbuto, and I developed the Servant Leadership Questionnaire (SLQ) to address this need. The SLQ measures five factors identified as important to the concept: (1) altruistic calling (2) emotional healing (3) persuasive mapping (4) wisdom, and (5) organizational stewardship.
The original description of servant leadership by Greenleaf (1970) and others suggest that this philosophy of leadership leads to more empowerment, wisdom, health and commitment. We are now in the process of examining whether strong servant leaders gain these outcomes in addition to standard productivity measures. Some preliminary findings indicate there is some substantiation for these outcomes. Although much more research is needed, it does seem that the servant philosophy fits well with the land grant emphasis and building the kind of commitment necessary to sustain service to others.

School of Biological Sciences
cwood1@unl.edu
Dr. Wood is the Director of the Nebraska Center for Virology. His laboratory studies the transmission and evolution of viruses, particularly HIV, and the risk factors that are involved. Our research involves collaboration with University Teaching Hospital in Zambia. Zambia is a country in central Africa where HIV/AIDS is prevalent. One of the projects is to study how HIV is transmitted from mothers to their infants, and how the virus evolves into new strains in the infected infants. Our research shows that HIV can evolve rapidly in newborns, with new strains being produced that are resistant to the infant’s immune system defenses. A parallel project is to study the transmission of a human herpesvirus, known as the Kaposi’s sarcoma virus, which is linked to a common cancer Kaposi’s sarcoma in AIDS patients. The focus is to determine how frequent is the infection by this virus, its route of transmission and the mechanism that this viruses causes cancer, especially in AIDS patients.
