My research focuses on mammalian biodiversity and conservation of African small mammals. I worked for several years in the rain forest of Madagascar surveying small mammal communities and primates. I served as Team Leader on the Ghana Coastal
Wetlands Management Project which established a series of long-term biodiversity monitoring sites in Ghana, West Africa (this project was funded by the
World Bank’s Global Environment Facility).
In 2001 I studied the rare hero shrew in the Bwindi Impenetrable Forest of Southern Uganda on a National Geographic Grant.
I am involved in a long-term study of the stream ecosystems surrounding Seneca Lake in an effort to develop a model of the Seneca Lake Ecosystem.

I have many research interests including a long standing interest in the mammalian biology and conservation of African small mammals. I''ve worked in a variety of locations in Africa the Carribean, and South America. In Africa, my research focuses on mammalian biodiversity and conservation of African small mammals.
I worked for several years in the rain forest of Madagascar surveying small mammal communities and primates. I recently serves as Team Leader on the Ghana Coastal Wetlands Management Project which established a series of long-term biodiversity monitoring sites in Ghana, West Africa.
I co-leaded an expedition to Uganda''s Bwindi Impenetrable National Park in summer 2001 to study and film the hero shrew with Dr. Dennis Cullinane from Boston University. My interest in mammals led to the publication in 2000 of a textbook on mammals with Drs. T. Vaughan (Northern Arizona University) and N. Czaplewski (University of Oklahoma).
In addition, I maintain my interests in the evolution of the neuromuscular system in vertebrates. I am particularly interested in the relationship between muscle biochemical properties and motor unit function.
Recently I have begun work on a long-term project to study the ecology of aquatic invertebrates in the freshwater streams of the Finger Lakes. My students and I hope to use aquatic organisms as bioindicators of ecosystem health. Ultimately we would like to build a mathematical model of the Seneca Lake Ecosystem that could be used to predict future changes to the ecosystem.
Finally, I am at work on a Field Guide to the Natural History of the Adirondacks.
