Research Summary
I am broadly interested in understanding how population and community dynamics are shaped by species interactions. My ongoing research addresses how top-down forces influence insect behavior and physiology, contribute to trophic cascades and structure ecological communities.

Much of my work focuses on the underappreciated role that predation risk has on arthropod ecology, which has importance in both natural and agricultural systems. A major element of this work is understanding how insects perceive predation threat by detecting predator odors.
