Areas of Expertise

I am a behavioral evolutionary ecologist who is interested in how ecological processes and sexual selection lead to the evolution of complex phenotypic traits. My research addresses these two focal questions: 1) How do ecological pressures drive evolutionary patterns of behavior? 2) What is the role of behavior in signaling fitness and generating species diversity?

I address these two areas using field studies and laboratory experiments. I seek to understand the connections between behavior and the ecology or evolution of a species. Although I concentrate primarily on amphibians and reptiles, I have experience working with other taxa, notably mammals and insects. I have worked with undergraduate students in their development as new scientists in a variety of research areas including behavior, ecology, and evolution of animals or with animal/plant interactions.

If you are an undergraduate at LHU interested in working with me, view my profile and research on LinkedIn, ResearchGate, or view my CV.
