I am an evolutionary biologist with broad interests in both evolution and ecology. However, my main areas of expertise lie in molecular ecology & evolution and population genomics. I am particularly interested in the role natural selection plays in driving patterns of molecular variation within and among natural populations, and how demographic changes in populations can impact levels of adaptive molecular variation. Though I have worked on a cross section of life, from bacteria to humans, I have to admit to a strong bias towards marine organisms, fish in particular. Below is a brief summary of my research interests.
When not working I try to spend as much time as possible with my family. I train extensively in Aikido (http://www.cityaiki.com) and Daito Ryu Aikijujutsu. My other interests include SCUBA diving whenever I can, ocean kayaking, fishing, and generally just being outside enjoying the natural world.
Ph.D., SUNY Stony Brook, Department of Ecology and Evolution 1992
M.Sc., SUNY Stony Brook, Marine Science Research Center 1982
B.S., North Carolina State University 1979
- Role of natural selection in driving patterns of molecular diversity.
- Genes associated with the adaptive and innate immune system as a model for understanding the molecular basis of adaptations in natural populations.
