|Messages to Students|
As coordinator of the M.S. Program in Environmental Science Id like to thank you for visiting our WebPages. Over the past six years we have strived to develop a top-notch masters program in environmental science here at UNH, with a suite of up-to-date and hands on courses that provide excellent preparation for a career in this field. We have a great group of students with a diversity of backgrounds and experiences. My own scientific interests are
Fields of Specialization:
Current Research Interests:
Currently I am working on several projects, including:
1) investigating large-scale patterns and processes in seafloor communities in Long Island Sound using a variety of underwater remote sensing techniques (side scan sonar, remotely operated vehicle with video),
2) the effects of natural and man-made disturbances on the benthic fauna of estuaries,
3) estuarine restoration, and
4) the life history and demography of marine fauna relative to different types and scales of disturbances.
