current research

  • Carbon dioxide efflux, effects of competing vegetation and soil nutrient availability on microbial respiration (Garden of Eden experiment).
  • Symbiotic N fixation by bitterbrush and ceanothus in eastside pine forests.
  • Changes in microbial activity and soil nutrient pools in response to manipulation of understory vegetation.
  • Long-term forest sustainability following thinning, prescribed fire, and fertilization.
  • Effect of organic matter content and soil porosity on decomposition processes (LTSP study).

research interest

To improve our understanding of nutrient cycling processes in managed forests. My work focuses on the regulation of soil carbon and nitrogen cycling by bacterial and fungal communities. Applied research projects are designed to provide new knowledge on the function of microorganisms in relation to forest sustainability.
