Avehi is a J. Lloyd Huck Graduate Fellow in the Ecology Program at Penn State. She has a bachelor’s degree in Biology from Reed College, Oregon. Her undergraduate thesis research was on the effects of social rank on the gut microbiota of cichlid fish. Avehi’s research investigates the role of olfactory processes in the evolution of specialization in squash bees. Specifically, she is using comparative genomics to characterize olfactory gene evolution associated with pollen specialization in the clade Eucera. Alongside, she is combining field studies and electrophysiological methods to understand the sensory mechanisms underlying host plant recognition in squash bees.
