I am an associate professor in the Laboratory for Elementary Particle Physics (aka LEPP), a part of the Cornell Physics Department. My physics interest lie in in the energy frontier. See, for instance, The Quantum Universe for particle physics' attempt to explain itself to the outside world. There are also some LHC blogs that you can read to see what life is like for a particle physicists. I don't blog there but I know a lot of people who do.

I am a collaborator in the CDF experiment at Fermi National Accelerator Laboratory in Batavia, IL and in the CMS experiment at the CERN LHC in Geneva, Switzerland. Long ago, I worked on the Sudbury Neutrino Observatory (SNO).

To learn more about what I do, see a public presentation I gave at an event marking the start of the Large Hadron Collider on September 9, 2008. You can also see a somewhat older this powerpoint presentation (or PDF) that I gave to REU students in 2006.

I am also an avid amateur photographer. See some of my photos in the badge at right!

If you are trying to schedule a meeting with me, send me email (public calendar view no longer works since Cornell switched to Outlook.) See my address below.
