Curriculum Vita

I am intrigued by questions such as: "Why is there mass?" and "Why do the four fundamental forces in nature appear to be different?" Finding answers to these questions will certainly involve a deeper understanding of the phenomenon of electro-weak symmetry breaking. So it is in this area that my research interests lie. I have probed this phenomenon using a variety of tools - the tau-lepton, the b-quark, searches for new physics - and at a variety of particle accelerators - LEP, the Tevatron, LHC. I am currently a member of the large, international collaborations D0 at Fermilab outside of Chicago and Atlas at CERN near Geneva. We keenly anticipate making breakthroughs in our knowledge of electro-weak symmetry breaking in the years to come using these energy-frontier accelerators.

As an experimentalist, I am also fascinated by the devices we build to make our measurements. In particular, I am involved in several projects developing high-speed electronics to aid in the collection of the unprecedented amounts of data we will accumulate in the near future.
