Education

I did my Undergraduate work at the University of California at Santa Cruz. I started off majoring in Physics and Mathematics, but burnt out finishing my Physics courses my second year, and fled into the world of Greek and Latin literature. Math never got boring, and so in the end I graduated with three majors: a BS in Physics, and BAs in Pure Mathematics and Classics. Assorted honors, scholarships, etc.

Here at MIT I am now a Qualified Physics PhD candidate. That means I’ve passed the two written and one oral Physics General exams, and am now full time involved in my thesis research.

In terms of Accelerator physics, I’ve attended the United States Particles Accelerator School three times; taking classes on basic accelerator physics, high brightness beams, wakefields, and microwave cavity design. I also attended the International Accelerator School for Linear Colliders in Japan, which included lectures on the International Linear Collider parameters, design, and experiments.

Research Interests

I maintain, operate, and conduct experiments on a 15-30 MeV, 17.14 GHz Linear Accelerator. This is the highest frequency stand alone accelerator in the world. The following is a list of previous, current and future ideas and interests:

• Photonic Band Gap accelerating structures
• Coherent Transition and Smith Purcell Radiation
• Bunchlength Diagnostics
• Innovative High Gradient accelerating structures
• RF breakdown

Recent Publications and Talks

• Particle Accelerator Conference 2005

• Transition Radiation Talk

• Transition Radiation paper

• EFIE Smith Purcell Experiment PRSTAB
