I was captivated by the complexity in biological systems when I was an undergraduate at Swarthmore College. While there, I studied dragonfly wing structure with Rachel Merz and anemone behavior with Liz Vallen. After graduating, I worked in the lab of Steve DiNardo at the University of Pennsylvania School of Medicine, where I was given the opportunity to shift my focus to Drosophila developmental genetics. There, my research centered on how planar polarity is established in a growing fly. In the Extavour Lab, I hope to explore early insect development, with the goal of uncovering a little bit more about how different groups have evolved.
I am a graduate student in the OEB program, and hold a National Science Foundation Graduate Research Fellowship.
