ProfileI am an Associate Professor in the Department of Physics at the University of Alberta in Edmonton, Alberta Canada. I received my Ph.D. at Northwestern University in Evanston, Illinois. Originally from St. Louis, Missouri, I did my undergraduate education at Washington University in St. Louis. Hence the above picture of the Arch. Also the ‘Welcome to the Top’ sign at left greets you when you step off the elevator at the top of the Arch. But I think its also fitting for research done way up here in Edmonton! I have a strong interest in superfluidity and superconductivity, in particular superfluid 3He at ultra-low temperatures. My lab is working on superfluids in nanoscale geometries, nanoscale superconductivity, and the quantum properties of nanomechanical resonators. Drop me a line, or stop by my office (CCIS 3-199) or my labs (CCIS L2-100 & L2-102), if you want to discuss the opportunities for post-doctoral, graduate, or undergraduate research positions in our lab.
