We study fisheries and aquatic ecosystems – including marine, estuarine, and freshwater environments. The word fishery refers to an entire social-ecological system including a wild fish or invertebrate population, as well as the fishermen and processors who harvest and sell the fish (in a commercial fishery), and the managers who regulate the fishery to prevent overharvest. Our research ranges from field studies of endangered salmonids in Mongolia to meta-analysis of stock assessment data to better understand fish population dynamics. If you’re interested in learning more about what we do, please follow the Research link on the sidebar to the left.

I’m originally from Callicoon, NY – a small town on the Upper Delaware River. I went to Cornell U. for a BA in Biology & Society and then to the U. of Maryland Chesapeake Biological Lab for an MS in Marine Science. I did my Ph.D. research at the U. of Wisconsin Center for Limnology, followed by a postdoc (Smith Fellowship) at U. of Washington. My research interests are a mix of fisheries science and aquatic (marine & freshwater) ecology. In my free time I enjoy fishing (big surprise!), sailing, hiking, and most other outdoor pursuits.
