Dissertation (2013): Climate Change Effects on Lake Erie Yellow Perch Reproduction and Recruitment

Research Interests:
My research interests intersect the basic and applied fields of aquatic ecology and fisheries and aquatic resource management.  I am particularly interested in conducting research that combines empirical approaches (lab or field) with ecological modeling to investigate processes regulating fish populations, communities and aquatic ecosystems. For my PhD research, I conducted field studies, laboratory experiments, and ecological modeling to investigate the effects of climate change on reproduction and recruitment of a cool-water fish species, yellow perch, in Lake Erie. Specifically, I investigated how i) altered thermal regimes during winter (time when egg development occurs) and ii) increased duration of hypoxia (reduced oxygen availability) during late summer/early fall (time when energy reserves are acquired for egg development) affect reproductive development and subsequently, the number of juveniles produced annually. Currently, I am a postdoctoral fellow at Auburn University working with western Alaskan Chinook salmon populations, using Bayesian modeling approaches to quantify stock-specific run-timing and abundance in data-limited situations.
