Celeste Brown, Ph.D.
Research Associate Professor
Dr. Celeste Brown has two research areas, how gene regulation changes in response to selection, and the evolution of disordered proteins. The link between these two disparate areas is that often proteins involved in gene regulation are disordered. The gene regulation studies involve laboratory-based research and the disordered protein studies involve bioinformatics approaches.

John A. Byers, Ph.D.
Professor
I am an animal behaviorist primarily interested in behavioral development, play, sexual selection and female mate choice. I am a member and Fellow of the Animal Behavior Society. I maintain a longitudinal study of a population of pronghorn (Antilocapra americana) on the National Bison Range in western Montana. Projects now underway in this study, which has run since 1981, are measurement of costs and benefits of female mate choice and evaluation of the fitness consequences of inbreeding in the population.

Larry J. Forney, Ph.D.
University Distinguished Professor<br>Director of IBEST
The research done in Dr. Larry Forney’s laboratory centers on the diversity and distribution of prokaryotes. Both field and laboratory studies are done to explore the temporal and spatial patterns of community diversity, as well as factors that influence the dynamics of inter- and intra-species competition. In addition research is done to understand how spatial structure and the resulting environmental gradients influence the tempo and trajectory of adaptive radiations in bacterial species and the maintenance of diversity. Most of these studies are highly interdisciplinary in nature, and done in collaboration with mathematicians, statisticians, computer scientists, geologists, environmental engineers, physicians, and clinical scientists.

Nicole Grieshaber, Ph.D.
Research Assistant Professor
Chlamydia is a group of obligate intracellular bacterial pathogens causing a wide variety of diseases in humans and other animals. In order for Chlamydia to successfully establish a productive infection it must complete multiple rounds of differentiation, alternating between the infectious elementary body (EB) cell type and replicative reticulate body (RB) cell type. My research focuses on the molecular mechanisms and pathways that regulate the developmental cycle of Chlamydia.

Scott Grieshaber, Ph.D.
Assistant Professor
My laboratory studies the pathogenesis of the obligate intracellular bacterial pathogen Chlamydia. In my lab we pursue two main areas of interest: 1) understanding the cytological effects of chlamydial infection on the host cell, and 2) understanding and dissecting the mechanisms of chlamydial differentiation with an eye to developing novel genetic tools in this difficult to manipulate pathogen.

Associate Professor
My research interests are at the intersection of microbial physiology and evolution, and span from experimental and computational approaches. On one hand, we use experimental evolution as a tool to uncover novel genes and functions. On the other, we apply systems-level models of metabolism to try to predict genetic interactions, optimal phenotypes, and evolutionary outcomes of evolving populations.

Diana Mitchell, Ph.D.
Research Assistant Professor
My current research interests involve immune cell function in the central nervous system, specifically the retina. I am particularly interested in microglia, which are resident innate immune cells of the central nervous system. Current efforts employ the zebrafish model system and seek to understand the role of microglia in the development of the retina, how microglia respond to neuronal cell death, and how they may support or be detrimental to neuronal regeneration. I also contribute to research efforts in Dr. Deborah Stenkamp’s lab, where we are investigating mechanisms of photoreceptor fate decisions in the developing retina.

Christine E. Parent, Ph.D.
Assistant Professor
Research in the Parent lab centers on the evolutionary process of diversification in lineages exposed to novel environment. Our general approach is to (1) observe present-day patterns of biodiversity to infer past evolutionary processes, and (2) test those processes with manipulative experiments in laboratory populations. We use field observations, comparative analyses, laboratory experiments, molecular phylogenetics, and integrate them with theoretical modeling. Island systems (natural or experimental) are the main focus of our research attention.

Matt Settles, Ph.D.
Research Assistant Professor
Much of my research work and interest is focused on the applied analysis of high-throughput data, including microarray data, genotype data, and high-throughput sequencing data from machine output to data visualization and statistical assessment. This typically involves the computational manipulation and interpretation of very large datasets in a wide range of disciplines, often applying bioinformatics techniques not originally designed for a particular data type in order to ask, and answer, new and interesting biological questions.

John "Jack" M. Sullivan, Ph.D.
Professor
Our understanding of the processes of nucleotide substitution (DNA sequence evolution) has been expanding greatly over the last 10 years. Furthermore, it has become apparent that ignoring such processes as heterogeneity of base composition, substitution pattern, and rate variation among nucleotide sites can compromise attempts to estimate phylogeny from DNA sequence data. Therefore, model-based analyses of DNA sequence data have become increasingly wide spread because such approaches afford the investigator the opportunity to account for such processes explicitly.

David C. Tank, Ph. D.
Associate Professor and Director, Stillinger Herbarium
I am a plant systematist and am broadly interested in the investigation of the patterns and processes that shape plant biodiversity. In general, my research is focused on the use of molecular methods to reconstruct phylogenetic relationships in plants and the application of phylogenetic methods to understand plant evolution. The evolutionary causes and consequences of processes such as hybridization, polyploidy, pollination biology, biogeography, rapid diversification, and niche evolution can only be understood in light of a robust phylogenetic hypothesis, and these hypotheses are a necessary component of modern taxonomic treatments and classification systems. Research in my lab is directed at multiple levels of plant phylogeny and current projects range from comparative phylogeography of the Pacific Northwest inland rainforest communities, to the study of species boundaries and diversification among very closely related species, to patterns of diversification among some of the major lineages comprising the plant tree of life.

Eva Top, Ph.D.
Professor<br>Director of BCB
My research is currently focused on the evolution and ecology of plasmids that transfer to and replicate in a broad range of bacteria. Plasmids are mobile genetic elements found in most bacteria. Because they readily transfer between different types of bacteria under natural conditions, they play an important role in rapid bacterial adaptation to changing environments. A good example is the current epidemic of multiple antibiotic resistance in human pathogens, which is largely due to the spread of multi-drug resistance plasmids. Although plasmid-mediated gene transfer is now recognized as a key mechanism in the alarming rise of antibiotic resistance, little is known about their host range, their ability to invade bacterial populations in the absence of selection, and their genetic diversity. We are addressing these questions using various Proteobacteria and plasmids as model systems.

Holly A. Wichman, Ph.D.
University Distinguished Professor
The Wichman Lab studies viruses and their subcellular relatives, transposable elements. These two lines of research are united by a molecular approach and a strong evolutionary context. L1 elements have been active in mammals for over 150 million years and make up about 20% of the genome. Most of the copies in the genome are ancient molecular fossils, so it is a challenge to sift through all of the old copies to find those that have been recently active.
