My research concerns the understanding of how physical and biological constraints influence the rates of energy and mass exchange between the biosphere (e.g., forests) and the atmospheric layer adjacent to the ground surface. This research is necessary to understand the impacts of atmospheric composition changes on both the Earth’s climate system and air quality in response to increases of transport of materials from the biosphere to the atmosphere and vice versa. My research involves several facets ranging from investigations in the laboratory where I develop and test measurement systems before their field deployment, to research in the field where the complex interactions between terrestrial surfaces and the overlying atmosphere are studied employing state-of-the-science observing systems. As a micrometeorologist, I study the layer of the atmosphere where the influence of turbulence and radiative transfer are the greatest.  Over the years I have effectively collaborated with atmospheric chemists and ecologists on field projects that have taken me to places such as the high Arctic, Brazil, several places in Africa, and many places in North America.  Below are additional details on my core research areas.

• Ozone deposition processes
• Biogenic hydrocarbons
• Carbon sequestration
• The atmospheric boundary layer
