Professional Interests

Our knowledge of the small-scale structure of the universe relies heavily on accelerator experiments at the highest energies. I am involved in research on accelerator and experimental high energy physics, concentrating on critical issues for future accelerator facilities to enable further advances in the energy frontier.

My current focus is the International Linear Collider, a 0.5-1 TeV electron-positron collider under design which, if realized, will be the most challenging accelerator of its kind and possibly the most complex scientific instrument ever built. The machine is based on superconducting radio frequency (scrf) cavity technology and its feasibility hinges on achieving the highest performance from accelerating cavities by surface processing techniques. Fermilab is in the process of building scrf R&D infrastructure in support of a future bid to host the collider in Illinois.

I have been working on ionization cooling, a muon-beam cooling technology that has not been demonstrated in practice and forms the basis for a class of accelerators (Neutrino Factory or Muon Collider) that have never been built. My research spans component development (MuCool project at Fermilab) including rf cavity diagnostics and experimental demonstration (MICE experiment at Rutherford Lab) as well as software development and simulations.

I started out by studying targetry for muon-based accelerators and measured pion production cross sections in my thesis experiment (BNL-AGS-E910) at Brookhaven Lab. I am also a member of the MIPP experiment at Fermilab which has continued hadronic production measurements.
