By day, I’m a scientist. My ongoing research falls under two broad headings:

The Evolution and Functional Morphology of Intromittent Organs. Or in plain English, how penises work. Yes, really. I’ve worked on mammals and turtles, and I’m currently collaborating with Brandon Moore (Sewanee, University of the South) and Patricia Brennan (Mount Holyoke College) to figure out how the system evolved in archosaurs.

Want to know more? Check out the talk I gave about penis biomechanics at TED MED 2012.

Sexual Dimorphism in Neural Circuitry.

I’m collaborating with Joseph Bergan (UMass Amherst) to describe the connectome of one subset of neurons in a sexually-relevant region of the brain.
