Overview

Currently serving as the interim director, I also have a three-way appointment in the School of Plant and Environmental Sciences covering 50% research, 30% teaching and 20% extension.  The foundation of my research program has been about managing plant diversity in forage-livestock systems to improve their productivity.  I currently teach three courses within the School, and have a small extension program focused on diversifying forage-livestock systems with native prairie grasses.

Expertise

  • Plant Production Systems
  • Forage and Crop Ecology

Education

  • Ph.D. Ecology, Syracuse University, 1996
  • M.S. Environmental Pollution Control, Penn State University, 1988  
  • B.A. Biology, Rutgers University, 1986

One of the central themes of my research seeks to understand how we can better manage plant diversity to improve productivity and sustainability of forage-livestock systems in the eastern United States.  Among several on-going projects, my research group is exploring ways to integrate native prairie grasses and wildflowers together to create biodiverse pasturelands that will improve beef cattle production and increase bee populations for pollination services.
