Forestry, Ecology (Plant-animal interactions, Population ecology of forest insects, community ecology)
I study forest decline caused by many biotic factors: ambrosia beetles, forest defoliators, and deer. I address the most fundamental questions about balance of healthy forest ecosystems and causes of various types of forest declines. Interactions among multiple trophic levels and influence of biotic and abiotic factors have been the major scopes.
