Research Interests

My research focuses on the ecology and evolution of fishes. Research in my lab is conducted on a variety of organizational levels from the physiology of individuals to community dynamics over large spatial and temporal scales. Some of the recently completed projects included studies on phenotypic plasticity of physiological traits, mechanisms of reproductive isolation, hybrid zone dynamics, and assessing the dynamics of fish communities over time. Ongoing research projects being conducted by graduate students in the lab include ecological drivers of fish movement, evolution of life history traits, isolation of obligate headwater species, and thermal biology of stream fishes. Click here for more detailed information on research in my lab.

I am also curator of the USM Museum of Ichthyology. The collection is an invaluable resource for students and researchers interested in ichthyology. As of February 2013, the museum contains over 42,000 lots 800,000 specimens representing approximately 850 taxa.
