I study the evolution of aphid photoperiod response among geographical strains of pea aphids. In collaboration with Erin Bonner, I have so far focused on establishing response differences between strains originating from the northern and southern United States. I plan to continue working on this aspect of the aphid reproductive polyphenism for my senior thesis. Following graduation, I plan to pursue a PhD in conservation biology and a career in which I can work to protect our nation’s resources.
