SEX DETERMINATION

Sex determination is surprisingly variable in vertebrates and has a significant impact on their biology. Gender can influence morphology, behavior, reproduction, foraging mode, and growth. My current research looks at the patterns of primary sex determining mechanisms in vertebrates and examines the common molecular mechanisms among major vertebrate groups. This work is a collaboration with David Zarkower and Tariq Ezaz.

PHYLOGENETIC SYSTEMATICS - GECKO RESEARCH

Geckos are a diverse radiation of reptiles consisting of over 1,100 described species. My dissertation research utilized DNA sequence data to reconstruct the evolutionary relationships of geckos and used the resulting family tree to test hypotheses concerning biogeography, diversification, and character evolution.

CONSERVATION BIOLOGY - TURTLE RESEARCH

Tens of thousands of turtles are commercially harvested in Minnesota each year for sale to biological supply companies and the pet trade.  My M.S. thesis examined the impact of this harvest on painted turtle populations in Minnesota.
