My primary research focuses on the evolution and maintenance of symbioses particularly those occurring among bark beetles, ambrosia beetles and fungi. This work includes collaborative efforts with scientists in the US, South Africa, Sweden and Mexico. I also conduct research on various aspects of bark beetle ecology and management, including investigations into how bark beetles may affect the ability of forests to adapt to climate change.

I am an associate editor for the journals Insects, Journal of Economic Entomology, and Agricultural and Forest Entomology.
