Current Research Interests

My research aims to improve the scientific understanding of the biophysical mechanisms that govern the exchange of energy and mass between the Earth's surface and the lower atmosphere. 

Current research interests include:

  1. Development of micrometeorological and optical stable isotope techniques to trace the flow of carbon, nitrogen, and water between the land and atmosphere
  2. Reactive nitrogen cycling at the biosphere-atmosphere interface
  3. Methane and carbon dioxide budgets of tropical and temperate peatlands
  4. Biophysical modeling of land-atmosphere trace gas exchange
  5. Atmospheric transport and fate of herbicides/pesticides
  6. Boundary-layer inverse analyses
