Experimental High Energy Physics
I study the physics at the 10-18 m scale of the quantum universe using D0 data from the highest energy collider, the Tevatron, in the Fermi National Accelerator Laboratory, near Chicago, IL. My D0 work in 2009 resulted in 4 publications, 2 of which are already published, one submitted for publication, and the last one is in the final stages of submission. I also work on commissioning of the CMS experiment at the 7 TeV CERN LHC collider in Switzerland. This experiment has already started to take collision data and will likely to provide answers to many fundamental questions of physics such as: are there extra dimensions of space? What is the dark energy and what is the nature of the dark matter of the universe? What is the origin of mass?
I co-lead (with Dr. Halyo, Princeton U.) one of the 5 US CMS physics groups that helps young students and post-docs to prepare for upcoming CMS data analyses at LHC Physics Center at Fermilab. I also collaborate with Bharat Ratra and colleagues from CMU and Pittsburgh U. on several cosmology topics.
I am a PI of the DOE Outstanding Junior Investigator award grant I received in 2008. I am also co-PI in DOE grant GOPY531353 "Heavy quark and neutrino physics", and I am active in following grants: NSF Grant GOPY530504 "Quarknet", and NSF Grant GOPY000844 "Partnerships for Research and Education". I also receive supplementary funding in excess of $50,000 to support travel expenses and fund presence of stuff and graduate students at CERN.
