Research

My research interests lie in the field of experimental particle physics. Specifically, I have studied the decay of bottom and top quarks.  I have worked on the CLEO and CDF experiments, and am currently a member of the ATLAS collaboration, examining details of the W-t-b coupling. I also build trigger electronics for the ATLAS Liquid Argon Calorimeter.
