Ben graduated from Swarthmore College in 2006, where he studied Biology and English. Although he was initially drawn to bird biology in Alaska, he soon realized that his true research interests lay in Developmental and Evolutionary Biology. After graduating, Ben moved to Missoula, Montana, with nine of his friends, where he worked in Doug Emlen's lab studying the development and evolutionary diversification of horned beetles. Ben joined the Extavour lab in the Fall of 2008, and hopes to help figure out how the earliest stages of egg patterning vary between arthropod species possessing different ovary types.

Ben is a graduate student in the OEB program, and holds a National Science Foundation Graduate Research Fellowship. He successfully defended his Ph.D. thesis on April 18, 2014. Congratulations Ben! See photos of the champagne toasts here.
