I am
currently a Research Scientist at the Oregon State University, and
an Adjunct Research Fellow in the School of Forestry at the
University of Canterbury, New Zealand.
I worked for over five years as a Scientist at the New
Zealand Forest Research Institute after completing my PhD in
forestry at the University of Canterbury in 1994. My research
interests range from plant nutrition, photosynthesis and water
relations, and carbon allocation to roots, to regional-scale
ecosystem carbon and nutrient cycling and associated processes in
both natural and planted forests.
My current research activity is on regional analysis of NPP
and NEP in the Pacific Northwest forests, with specific focuses on
variations with climate, forest type, and stand age.
I have been a reviewer for Forest Ecology and Management,
New Zealand Journal of Forestry Science, Oecologia, and Scandinavian
Journal of Forest Research. Recent Publications Law
