Kathy is a broadly trained plant biologist and ecologist.  She works at Husson University in Bangor, Maine, where she teaches courses in biology, ecology, and botany and conducts research in forest and wetland ecosystem.  Before joining Husson, Kathy worked at Unity Environmental University in Maine and at the Cary Institute of Ecosystem Studies in New York.  She received her Ph.D. from the Cornell University Department of Natural Resources, where she investigated the influence of rich fen mosses on vascular wetland plants via effects on the biogeochemistry of shallow soils.  She also spent several years as a wetland environmental consultant in Nevada and as an associate ecologist for the New Hampshire Natural Heritage Bureau and The Nature Conservancy. 

Kathy’s research focuses on the role of plants in a changing environment.  She uses field and modeling approaches to investigate how plant species change interacts with environmental stressors to affect how ecosystems function.  She is currently involved in developing the Spe-CN forest ecosystem model to investigate the interacting effects of invasive insects and disease, climate change, and atmospheric nitrogen pollution on northeastern U.S. forests.
