Biographical Information

Since joining the faculty at Miami University – Hamilton, the primary focus of my research has involved combining the use of molecular genetic techniques with field studies to address questions in evolutionary biology and behavioral ecology.  Most recently I have been conducting mechanistic studies examining ecological and neurogenetic factors that may underlie individual differences in social and reproductive behavior among prairie voles (Microtus ochrogaster).  Although the prairie vole is a popular laboratory model for studying social monogamy, prairie voles show considerable variation in the degree of social and genetic monogamy within and between populations.  Ongoing research involves examining the affects of polymorphism in the gene encoding a receptor for vasopressin (V1aR) affects sociosexual behavior in prairie voles in field settings.  I am also involved in a project to assess the role of variation in neural estrogen receptor alpha (ER?) expression on sociosexual behavior in male prairie voles within a population-based and ecologically relevant framework to test the hypothesis that ER? expression is a biologically important mediator of male behavior in nature.
