I was a post-doctoral associate in the Department of Civil and Environmental Engineering at Syracuse University where I studied the effects of clear cutting and acid deposition on terrestrial ecosystems at the Hubbard Brook Ecological Forest.

My current research program in soil biogeochemistry emphasizes hydrological, biological, and geochemical processes and their interactions in terrestrial ecosystems. My current and recent research focus on three major areas: forest and rangeland biogeochemistry, volcanic soils, and trace element biogeochemistry. For more information on my research program you can examine my publication list. Teaching is the most rewarding aspect of my academic position and I enjoy teaching several courses at both the under-graduate and graduate levels (see course listing).

During the 1996 calendar year, I was on sabbatical leave in New Zealand where I collaborated with soil scientists at Massey University and Landcare Research. My collaboration with Max Turner led to the development of this module for Silicon Soils along with a case study on "Nutrient Cycling in California Oak Woodlands." More case studies relating to this module will be forthcoming.

I hope you enjoy this module on "Nutrient Cycling in Forest Ecosystems"! You can contact me at my University or via the chat facility, if you first send me an email message.
