BIO 3340  Evolutionary Biology
BIO 4342/5382  Topics in Evolutionary Biology


My research interests are in evolution, comparative genomics, environmental toxicology, and genetic epidemiology. My background is in genomics, specifically as it relates to adaptation, speciation and disease. My scientific interests are in two general areas. The first is in genomics and admixture of human populations. My lab is involved in several studies focusing on human population genetics and the analysis of the candidate disease genes in the Caribbean and Eastern Europe. My other interest is in evolution and conservation of endangered species in the Caribbean. I am involved in studies focusing on genome assembly and analysis; selection scans (Amazon parrots, Hispaniolan solenodons, African cheetah and elephants). Generally, I am interested in the study of genome diversity and its implications to evolutionary processes of adaptation and speciation.
