My research interests over the past decade have been quite eclectic; from fine scale movements of sandbar sharks in Delaware Bay for my MS degree, to "spillover"of grouper and snapper in the Bahamas while working as a Research Associate at the Caribbean Marine Research Center, and presently I am working on early marine survival of juvenile salmon in the Pacific Northwest under the supervision of Carl Walters. The common thread however, is the use of acoustic telemetry methods to collect ecological data on commercially, economically and socially important marine species.
My PhD thesis focuses on estimating freshwater and early marine survival and characterizing early marine migrations of spring Chinook in the Columbia River basin as well as Cultus Lake sockeye in the Fraser River using the Pacific Ocean Shelf Tracking (POST) array. By implanting transmitters into salmon smolts it is possible to track their movements and measure survival for up to thousands of kilometers. Since adult returns of both of these stocks have declined in recent years to warrant listing by the US Endangered Species Act (ESA) and Canada's Committee on the Status of Endangered Wildlife in Canada (COSEWIC), respectively, it is important to determine when and where mortality of these valued species occurs.
