My name is Patrick Boehnke and I am a T.C. Chamberlin Fellow at the University of Chicago. I am primarily interested in studying the formation of Earth, the Moon, and other solar system bodies as well as their subsequent evolution. Specifically, I have recalibrated the zircon saturation model and am gearing up to perform 40Ar/39Ar thermochronology on lunar samples to study their impact history. Additionally, I am interested in improving and developing new techniques for secondary ion mass spectrometry (SIMS) and the MegaSIMS.
