Curriculum Vitae

Interests and Research:


Pete's main area of research deals with aspects of climate and vegetation change. He currently is finishing a multi-year project funded by the National Science Foundation to determine if Douglas-fir and ponderosa pine forests of the Northern Rockies USA will grow faster under conditions of an increasingly carbon dioxid-rich atmosphere and a projected warmer and drier climate. Pete also has an ongoing project funded by ASU’s University Research Council investigating potential differences in radial growth rates and water use efficiency of ponderosa pine trees along elevational gradients in the northern Rocky Mountains. A third major ongoing project deals with a tree-ring reconstruction of rainfall from tropical cyclones on the North Carolina coastal plain from live and remnant wood from longleaf pine trees. In support of his tree-ring research, Pete operates the Department of Geography and Planning’s Appalachian Tree Ring Lab. Pete is currently sharing the lab with Dr. Saskia van de Gevel and any students interested in pursuing tree-ring research.

Pete teaches Climate Change, Introduction to Physical Geography, Weather and Climate, Global Climates and Meteorology, and graduate courses in Natural Hazards and Tree Ring Research.
