RESEARCH INTERESTS:

My research centers on how individual variation during different life history stages can influence population dynamics with the ultimate goal of aiding the management of aquatic species.  My current research examines maternal effects as a potential recruitment mechanism for yellow perch in Lake Erie. Specifically, I am looking into how spatial and temporal variation in female reproductive characteristics (e.g. fecundity, and energy density of somatic tissues and ovaries) can influence offspring survival and, ultimately, recruitment success in the western and central basins of Lake Erie.  The goal of this research is to combine empirical data with simulation modeling to identify optimal management strategies for this economically important species.
