Genetics

The study of heredity and gene action is one of the most rapidly developing fields of biology. A thorough understanding of genetics is essential to modern advances in agriculture, medicine, and many industrial fields dealing with biological diversity. The information content of genetic sequences is enormous and is rapidly becoming a major tool in tracing evolutionary lineages and in reassessing biological classification.

Daniele Armaleo

Associate Professor of the Practice of Biology

My research centers on the developmental and molecular biology of lichens, well differentiated symbioses between two or three evolutionarily unrelated organisms: specialized fungi on the one hand and algae or cyanobacteria on the... Full Profile »

L. Ryan Baugh

Associate Professor of Biology

We study nutritional control of development in the roundworm Caenorhabditis elegans. We are interested in the signaling pathways and gene regulatory mechanisms that enable the worm to reversibly arrest development and resist stress in response to starvation. We are also interested in epigenetic... Full Profile »

Amy Bejsovec

Associate Professor of Biology

My laboratory explores the molecular mechanisms of pattern formation in developing embryos. We focus on the Wingless(Wg)/Wnt class of secreted growth factor: these molecules promote cell-cell communication leading to important cell fate decisions during the development of both vertebrate and...

Sherryl A. Broverman

Associate Professor of the Practice of Biology

How inclusion of civic issues, international connections, and social engagement alters the cognitive and affective responses of non- major science students to science education. How course design impacts the demographics (gender, race, etc) of student enrollment in elective science courses.... Full Profile »

Xinnian Dong

Arts and Sciences Professor of Biology in the Trinity College of Arts and Sciences

Using Arabidopsis thaliana as a model system, my laboratory studies the mechanisms of plant defense against microbial pathogens. We focus on a specific response known as systemic acquired resistance (SAR). SAR,... Full Profile »

Kathleen Donohue

Professor of Biology

We investigate the genetic basis of adaptation, including the evolution of phenotypic plasticity and maternal effects, the adaptive value of epigenetic modifications, niche construction, dispersal, and mechanisms of multilevel natural selection. Full Profile »

Nicholas W. Gillham

James B. Duke Professor Emeritus of Zoology

The objective of my collaborative research with Dr. John Boynton in the Department of Botany is to understand how nuclear and organelle genomes interact in controlling the biogenesis of chloroplasts and... Full Profile »

Steven B. Haase

Associate Professor of Biology

Our group is broadly interested in understanding the biological clock mechanisms that control the timing of events during the cell division cycle. In 2008, the Haase group proposed a new model in which a complex network of sequentially activated transcription factors regulates the precise timing... Full Profile »

Alison Hill

Senior Lecturer of Biology

My primary focus in the department is instructional. I teach courses for both biology majors and non-majors.  I continue to develop and innovate the Molecular Biology lab curriculum and am involved in efforts to improve instruction by bringing formative assessment into our lectures. My non-majors... Full Profile »

Daniel P. Kiehart

Professor of Biology

Our intellectual focus is on identifying determinants of cell shape that function during development. Utilizing molecular genetic and reverse genetic approaches in Drosophila, we have shown that conventional nonmuscle myosin is necessary for driving both cell division and post-mitotic cell shape...

Thomas Mitchell-Olds

Newman Ivey White Professor of Biology in Trinity College of Arts and Sciences

We study genetic variation in plant populations, focusing on genes that influence traits controlling plant performance in an environmental context – a central theme throughout our research in natural and agricultural populations. Much of our work is focused on the genes that affect ecological... Full Profile »

H. Frederik Nijhout

John Franklin Crowell Professor of Biology

Fred Nijhout is broadly interested in developmental physiology and in the interactions between development and evolution. He has several lines of research ongoing in his laboratory that on the surface may look independent from one another, but all share a conceptual interest in understanding how... Full Profile »

Mohamed A. F. Noor

Professor of Biology

Research in my laboratory strives to understand what genetic changes contribute to the formation of new species, and how the process of genetic recombination affects both species formation and molecular evolution. I've been fascinated at how often genetic recombination plays a major role in any... Full Profile »

Zhen-Ming Pei

Associate Professor of Biology

My laboratory is interested in the early signaling events by which plants sense environmental signals and decode to give the appropriate responses. Upon perception of external signals, cell surface receptors trigger an increase in cytosolic free calcium concentration, which is mediated by ion... Full Profile »

Mark D. Rausher

John Carlisle Kilgo Professor of Biology

We investigate the evolutionary processes that cause change at both the phenotypic and genetic levels. We have particular interests in the genetic basis of adaptation and in the evolution of metabolic pathways. Our approaches include molecular dissection of ecologically important phenotypes and...

Allen G Rodrigo

Adjunct Professor of Biology

My research focuses on evolutionary bioinformatics and computatioanl biology. In particular, I am interested in the development of novel methods to study the evolution of genes, genomes, organisms and species. Full Profile »

David R. Sherwood

Associate Professor in the Department of Biology

Our research is directed at elucidating mechanisms underlying morphogenetic processes in development. We primarily use the model system C. elegans in our research, and combine powerful genetic and systems biology approaches with live-cell imaging to address three main topics:   Tissue...

Nina Tang Sherwood

Associate Professor of the Practice in the Department of Biology

We use Drosophila melanogaster as a model to understand nervous system development and function. A genetic screen for molecules important to these processes identified the fly ortholog of the spastin gene, which when mutated in humans leads to a progressive neurodegenerative disease called...
