I am a western New Yorker by birth, but an Adirondacker by choice. I first moved to the area in the mid 1990’s to attend Paul Smiths College as an Ecology and Environmental Technology student. On the first day of class I realized three things, that I wanted to live in the Adirondacks for the rest of my life, I wanted to be a biologist and I wanted to be a teacher – so far so good. My main area of interest is aquatic ecology. I am particularly curious about aquatic invertebrates and their interaction with fish, stream insect communities and invasive aquatic plants. My interests are not just in the water, I am also interested in teaching and learning about mammals, amphibians and tropical ecology. I really enjoy working with students on scientific research; some recent projects are listed below.

Gates, M. 2011. Investigation of food selectivity in the shredding Trichoptera using stable isotope analysis.

Bradley K. 2008. Composition and diel periodicity of macroinvertebrate drift in streams of the Northern Adirondacks (New York, USA).

Cannon, D. 2008. Is rock snot (Didymosphenia geminata) impacting macroinvertebrate abundance and diversity in the White River, Vermont?

Audette, C. 2006. Food web dynamics and vertical migration of the Chaoborus population in Lower Saint Regis Lake.

Washington, T. 2006. Viability of the Eurasian water-milfoil (Myriophyllum spicatum) seed bank in the sediments of Upper Saranac Lake.

Johnson, T. 2005. Effect of lake basin slope and topography on the distribution of brook trout (Salvelinus fontinalis) in a small Adirondack pond.

Bratten, E. 2005. Comparison of small mammal abundance and species diversity between riparian and upland habitats of the Smitty Creek Watershed.

Nead, T. 2004. Temporal shifts in the diet composition of yellow perch (Perca flavescens) in Lower Saint Regis Lake.

Boss, M. 2004. Creation of a region specific percent model affinity index (PMA) to monitor Adirondack water quality using benthic macroinvertebrates.

Interests and Activities

Understanding the environmental impacts of roadways, Evaluating the response of native aquatic plants to the establishment and management of Eurasian watermilfoil. Hydrology and nutrient loading in Upper Saranac Lake. Foodweb dynamics of Cercopagis pengoi in Lake Ontario.

I enjoy hiking, biking, snorkeling, ceramics, skiing, snowboarding, and having nerdy conversations with other academic types.
