My research here has broadly focused on two facets, anthropogenic alterations of aquatic environments (e.g., dam removal) and interactions between aquatic organisms and climate change. In a recent role as a post-doctoral researcher in the Wisconsin Cooperative Fishery Research Unit at UWSP, I worked on several projects that seek to understand the interactions between the climate and percid populations in the upper Midwestern United States. I am currently evaluating factors (e.g., lake growing degree days, spring temperature variation) that contribute to the success of the stocking of walleye within the context of a changing climate, with the aim of providing recommendations to ensure that future stocking events have the highest probability of success. At The Ohio State University, I worked as part of a larger project that was related to the ecosystem scale change in the riverscape after a dam removal on a mid size urban river. I sought to understand the changes in contaminant flux and interactions with the fish communities in the local river reaches.

Traceability is an important issue in seafood, which is plagaued by fradulent labeling. I have worked on projects using chemical markers to mark individuals, and used chemometrics to discern the geographic origins of shrimp products from major exporting countries.
