For her dissertation, Michelle chose to study Prothonotary warblers where both males and females display bright, yellow coloration. Her dissertation research examined the relationships between plumage coloration and mate choice, competition over nest sites, and determined if plumage coloration was a condition-dependent trait. She also examined patterns of extra-pair mating in Prothonotary warblers and the role habitat features may play in altering the strength of sexual selection. Michelle completed her PhD in 2010 at Washington State University; she worked with Michael Webster and Hubert Schwabl.
In the Hopkins lab, Michelle’s research focused on the interface between conservation biology and behavioral ecology. She examined the effects of trace element contamination from the Kingston coal ash spill on the production of ornamental plumage coloration in tree swallows and the potential effects of the spill on adult reproductive behavior and physiology. She also examined the influence of the spill on nestling development and physiology, including the development of personality.
Michelle is currently a postdoctoral research associate with Kendra Sewall in the Department of Biology at Virginia Tech. She will be addressing the influence of stress on mate choice and early gene expression in the social network center of female house finches. In order to address this question, she is developing a new method to experimentally manipulate corticosterone concentrations and developing an operant conditioning system that can also be used in mate choice trials.
