I'm an Assistant Professor in the Department of Physics and Astronomy at Union College, where I've been since September of 2001. This page is meant to provide a quick guide to what I do when I'm working.
My research is in the field of Atomic, Molecular, and Optical (AMO) Physics, specifically in using lasers to cool samples of atoms to ultra-cold temperatures (T ~ 1-100 μK, where 1 μK is one one-millionth of a degree above absolute zero) and studying what happens in collisions between ultra-cold atoms. At these low temperatures, the behavior of atoms is much different than at room temperature, and quantum-mechanical effects can dramatically change the collisional properties.
For more on laser cooling and the related field of Bose-Einstein Condensation, check out the BEC Tutorial put together by the University of Colorado. I also teach a two-week module on laser cooling for Physics 14.
I've also become interested in using the technique of Atom Trap Trace Analysis to measure trace amounts of contamination in ultra-pure gases used for exotic particle detectors. The ATTA technique uses laser cooling to measure the abundance of extremely rare isotopes or contaminant atoms by trapping and detecting individual atoms.
