In general, my research group investigates how pharmaceuticals, endocrine disrupting chemicals, and other pollutants that might enter the enivronment through man-made means negatively affect the behavior of the fish living in these polluted waters. Behavior is both a very sensitive and rapid endpoint of exposure and has important fitness implications. We study many different behaviors that are important for species survival, from exploration to courtship. In addition to this overarching theme, we are also interested in how and why individuals, even of the same sex and age, vary in their behavioral responses as well as the potential consequences of this variation.

Research

Current Research

Using behavioral, genetic, evolutionary, and hormonal assays to assess the sources of individual consistency and flexibility in responses to conflicting stimuli. The use of models, video playback, and live conspecifics to assess male and female behavior in fish. Using behavioral assays to determine the importance of social environment on male-male and male-female interactions in fish. Investigating sex differences in learning in Siamese fighting fish. Examining the mechanisms and consequences of inadvertent pharmaceutical exposure on fish behavior.

Research Interests

the influence of social environment on male courtship and aggressive behavior in Siamese fighting fish and threespine stickleback; consistent individual differences in male response to conspecifics and the effect of stimulus context on behavioral consistency; the interaction between social environment and hormones to produce behavior; mechanisms behind behavioral variation; pharmaceutical exposure effects on fish behavior
