About Dr. Richard Cobb

Dr. Cobb competed a PhD in Ecology from UC Davis in 2010 with research focus on sudden oak death, a damaging disease of California coastal forests. His research interests focus on understanding the underlying drivers, ecological impacts, and potential responses to insect and disease outbreak. Past and current projects aim to improve prediction of when, where, and why outbreaks occur as well as forest-level experimentation to change the course of outbreaks and reduce their economic and ecological costs. His teaching interests combine an interest in ecological science with the strong personal desire to improve forest management at regional and national levels. At Cal Poly, he teaches forest health (insects and pathogens), dendrology, ecology, as well as supporting many aspects of education in forest management.  Dr Cobb encourages inquiries into undergraduate and graduate research projects particularly related to forest management and forest conservation issues in California Native American communities.
