Patrick Ryan at DESY

I am a graduate student in the Physics Department at the University of Wisconsin-Madison working under the supervision of Professors Wesley Smith and Don Reeder.

I am conducting particle physics research as a member of the ZEUS Collaboration. The ZEUS detector measures electron-proton collisions in the HERA accelerator and is located at the DESY Laboratory in Hamburg, Germany.

The topic of my research is "Rapidity Gaps Between Jets in Photoproduction", which involves the investigation of the rate of color-singlet exchange between two high-energy jets in hard diffractive photoproduciton.

I served two years as the trigger coordinator for the ZEUS QCD working group .

The Wisconsin group at ZEUS is responsible for maintaining the Calorimeter First Level Trigger.
