Year Started at Paul Smith’s:  2021
Department: Natural Science
Program: Fisheries & Wildlife Science


As a fisheries biologist, I am interested in evaluating and understanding species interactions related to aquatic food webs and population dynamics. I have worked on various aquatic systems, including St. Lawrence River, Iowa Great Lakes, and Lake Oahe, evaluating organisms from crustacean zooplankton to sportfish species. Regardless of the  research, I use an integrated approach that relies on various study designs, including natural field experiments, experimental manipulation, and modeling to address applied fisheries and basic ecological questions. Although broad, my research interests revolve around several related topics: 1) how major ecological processes such as competition, predation, keystone species, movement patterns, and invasive species influence population dynamics of fish and aquatic ecosystems; 2) evaluating the effects of aquaculture and stocking practices on ecosystem function; 3) evaluation temporal changes in fish populations with various modeling approaches; and 4) evaluation of teaching techniques used in education programs. Although broad and diverse, my research interests provide an increased understanding of aquatic ecosystem structure, function, and ecology that ultimately enhances fisheries ecology and management and improves the training of future fisheries professionals.

As an educator, I have an innate passion for developing and implementing hands-on science courses. Throughout my professional development, I have continuously evolved my instruction style to meet the changing needs of my students while aligning with current teaching paradigms.  As an undergraduate and graduate student, I had the privilege of being a member of departments where the faculty created a friendly and safe learning environment that challenged me as a learner and allowed me to discover who I was as a scientist and person. It is this type of learning environment that I strive to create in my courses.
