Adjunct Assistant Professor
Soil Science

  • Veterinary antibiotics and soil microbial community characteristics
  • Flooding and soil chemical and biological characteristics
  • Herbaceous community responses to disturbances, such as clear-cutting and flooding

Research Summary

  • Research interests focus on the dynamic interplay between above-ground and below-ground communities and processes. Organic and inorganic inputs, management activities, vegetative communities, and disturbance affect soil microbial community characteristics. The stability of the soil microbial community may be important in maintaining soil fertility and soil quality.
