DeWitt Wallace Professor of Environmental Studies and Biology
interests include areas of
both Biology and
Science. I the past I have taught Ecology, Invertebrate Biology,
Physiological Ecology and Introductory Biology. More recently my
courses have included Aquatic Ecology, Environmental Science and Lakes,
Streams and Rivers.
was broadly trained in the area of organismal biology and ecology. My
recent research has been dealing with the biology and ecology of
freshwater mussels in river systems. In general, I am interested in
exploring the factors that influence the distribution and abundance of
these animals. In our current world, this includes examining human
impacts on the rivers that may influence the mussels that reside there.
As part of my research, I become involved in the conservation of
endangered species of mussels. As a group, mussels are one of the most
endangered groups in North America.
