Title: Fish Ecologist

 

Education:
1998 - B.S. University of Massachusetts at Amherst, Biology

 

Research Interests:
I am interested in how habitat fragmentation impacts the growth, survival, and movement of stream fishes and how the implementation of PIT Tag technology can help address this question. In July of 1999 I had the opportunity to become involved with the research and development of FDX PIT tag antenna arrays. We were able to develop a working swim thru model to be used at our long term West Brook Study Site. Salmonids (Atlantic salmon, brook and brown trout) in the West Brook have been individually tagged with 12mm FDX PIT tags from 1997 thru to the present. The application of PIT technology has allowed us to study habitat use and fragmentation in much greater detail. At This time we have 7 systems on the West Brook logging movement data continuously. I am also excited in improving our existing antennas as well as developing new custom designs. Designs we are currently working on are, portable wand, flat plates and high conductivity systems.
