rob_dunnRob Dunn (North Carolina State University)

Dr. Rob Dunn is a biologist and writer in the Department of Biological Sciences at North Carolina State University. The science Dunn mentors attempts to use many different approaches to understand the stories of the species all around us and how they have changed or might change in the future. Often those species are ants and their societies, other times mosquitoes and the diseases they vector or rare carnivores and the parasites they host. Central to all of this work is the sense that much of what we assume someone else knows (such as which species live around us in cities) is totally unknown. The unknown is large and wonderful and Dunn and his collaborators, students, postdocs and other researcher scientists, love to spend their days in it.

Dunn’s writing focuses on the stories of the scientists behind the science, who they are, what they do and how and why they did it. Dunn’s writing has appeared in Natural History, BBC Wildlife Magazine, Scientific American, Smithsonian Magazine, National Geographic and other magazines. His first book, Every Living Thing, was awarded the National Outdoor Book Award for Natural History writing. His new book, out in the spring of 2011, The Wild Life of Our Bodies, examines the long human relationship with other species (be they tapeworms or tigers) and how changes in those relationships are affecting our health and well being.

Jim Evans (University of North Carolina, Chapel Hill)

Dr. Jim Evans’s major professional interests lie within the field of clinical cancer genetics, the use of high-throughput sequencing in clinical medicine and public policy as it relates to genetics. He directs the Clinical Adult and Cancer Genetics Services at the University of North Carolina. The clinic evaluates and counsels patients who have (or are suspected of having) a variety of genetic conditions, including high risk for cancer. This comprehensive clinic provides evaluation, counseling and risk assessment through pedigree analysis and genetic testing when appropriate. The clinic has grown substantially since its inception and now sees, on average, approximately 20 patients per week in consultation. While breast/ovarian cancer comprises the bulk of its activity, the clinic sees numerous patients with elevated risk for a great variety of different conditions and malignancies.

Dr. Evans’s research interests focus primarily on the use of massively parallel DNA sequencing for gene discovery and the use of such technology for clinical diagnosis. He is also interested in attitudes towards the use of genetic information. These interests are combined in a current effort in which whole exome sequencing is being pursued in a large number of patients with a variety of indications.

He is also interested in policy issues as they relate to genetics. Towards this end, Dr. Evans has been highly active in scientific education of the US judiciary at the State Supreme Court and Federal level, as well as at the Supreme Court level internationally. These efforts were described in an article in the New York Times in 2008. His activity in policy issues resulted in testimony before the US Congress in 2010 regarding the regulation of direct-to-consumer genetic testing. Dr. Evans was a member of the advisory committee to the US Secretary of Health and Human Services on Genetics, Health and Society and spearheaded that committee’s task force that investigated gene patenting and its effect on patient care.

Dr. Evans is deeply interested in evolutionary theory and how evolution relates to medical issues (see Evans JP. JAMA 2009;301(6):663-665. doi:10.1001/jama.2009.102). He lives in Durham, NC with his wife and enjoys traveling.

Steve -tick article photoSteve Meshnick (University of North Carolina)

Dr. Steve Meshnick’s research group uses methods from molecular and evolutionary biology to understand the epidemiology and pathogenesis of infectious diseases. Malaria parasites are under purifying selective pressure from antimalarial drugs and balancing (diversifying) selective pressure from host immunity. They have been using next-generation sequencing to understand the genetic diversity of malaria parasites and how it affects both drug and vaccine efficacy. They are also using this genetic diversity as a tool to understand how malaria evolves and diffuses in the Democratic Republic of the Congo. Malaria is also a tool to examine the evolutionary “conflict” between mother and fetus; mother and fetus compete for nutrients and fetal survival depends on modulating the maternal immune response. They have shown that malaria has a more severe effect in poorly nourished pregnant women. More recently, they have been studying the microbiomes of disease vectors, especially ticks.

Fred Nijhout (Duke University)

Dr. Fred Nijhout is broadly interested in developmental physiology and in the interactions between development and evolution. He has two ongoing lines of research. (1) The mechanisms that control body size and the relative size and shapes of appendages. Size and shape are the two most characteristic features of species, yet surprisingly little is known about the mechanisms by which animals grow to their species-characteristic size, and then stop. Nor is much known about the mechanisms that control how appendages grow to the correct proportion with body size. Research involves the hormonal control growth and the mechanisms that control the temporal patterns of hormone secretion that regulate growth. (2) The development, genetics and evolution of complex traits. Complex traits are those whose variation is affected by many genes and environmental factors and whose inheritance does not follow Mendel’s laws. In practice this involves understanding how genetic and developmental networks operate when there is allelic variation in their genes. This work attempts to reconstruct complex traits through mathematical models of the genetic and developmental processes by which they originate, and uses these models to study the causal pathway by which mutations affect traits. Much of current work centers on complex metabolic systems relevant to human health, and the mechanism by which these systems are either sensitive or robust to mutations and environmental factors.

ParkerPhotoWilliam Parker (Duke University School of Medicine)

Work in the Parker lab focuses on the immune system and its role in biology and disease. Dr. Parker’s group is currently involved in three primary areas of investigation related to medicine, as well as basic work in protein folding. His laboratory is interested in the support of bacterial growth in the lumen of the gut by the mammalian immune system. Current work in the laboratory suggests that the model of “immune inclusion” is ubiquitous in mammals and is also important in non-mammalian species (e.g., amphibians). Secretory IgA and mucin, the major component of mucus, facilitate adherence of bacteria to the proximal part of the large bowel. Thus, the immune system supports biofilm growth by commensal (beneficial) bacteria. Use of this model of gut immunity has enabled his laboratory to achieve the first growth of bacterial biofilms on live, cultured gut epithelial cells. Further, this model provides an apparent function of the human vermiform appendix, an issue that has been in question since Leonardo da Vinci first described the appendix in 1506 A.D. The laboratory is also interested in the effects of chronic aspiration of gastric fluid on lung transplant recipients. In pursuit of this goal, they have developed the first experimental model of chronic aspiration. Finally, they are interested in the Biome Depletion Theory, an “evolutionary mismatch,” or factor in our current environment that leads to disease because it is incompatible with our evolved genetic makeup. This model of disease can account for the high burden of disease in modern society despite the herculean efforts of the modern healthcare system. Their work on the biome has focused on both bacteria and eukaryotic organisms (“germs and worms”). Their current work related to the biome and human disease is focused on the use of “helminthic therapy” to avert disease in humans.

KyleSummersKyle Summers (East Carolina University)

Dr. Kyle Summers has broad interests in evolution, particularly evolutionary ecology and evolutionary genetics. His students and him have carried out research on reproductive strategies and larval life history in frogs. They have also worked on the evolution of aposematism and mimicry.Summers is interested in molecular systematics and the use of phylogenetic trees to inform analyses of ecology and adaptation. Evolutionary ecology and phylogenetics are complimentary, because it is important to consider the effects of ecology on adaptation in a historical context. Similarly, phylogenetic information can be used to investigate the influence of ecological and social factors on adaptation in comparative analyses. Most of the field and laboratory research has focused on the poison frogs of the family Dendrobatidae, a group of toxic frogs in Central and South America. These frogs vary in diet, coloration and toxicity, making them excellent candidates for research on aposematism and mimicry. The reproductive ecology of these frogs is also interesting and complex, involving territoriality, intra-sexual competition for mates, prolonged courtship, mate choice, long term associations between males and females, extensive parental care by one or both sexes, trophic egg-feeding, and larval cannibalism. The wide spectrum of variation in life histories across the poison frog family make this group an excellent system for comparative studies. (website)

Summers is also interested in evolutionary approaches to human health and behavior. Evolutionary biology is highly relevant to many issues crucial to human health and disease, yet few medical researchers take an evolutionary perspective. Vast amounts of data relevant to issues of central interest in evolutionary biology, such as the evolution of senescence and parasite-host coevolution, are being generated by biomedical researchers, but use of these data to test evolutionary hypotheses is uncommon. His collaborators and him have attempted to develop hypotheses relating specific conditions to environmental, social and genetic factors in an evolutionary framework. They are also attempting to test specific hypotheses using molecular evolutionary genetic analyses of genomic data available from public databases such as GenBank. (website, website)
