I work in the field of experimental high energy physics (HEP). In this field my colleagues and I study the properties of elementary particles and fundamental forces. One of our ultimate goals is recreating the conditions that existed in the universe a few nanoseconds after the Big Bang and providing the data to help explain the baryogenesis, i.e., the asymmetry between matter and antimatter in visible universe.
In my field it often takes an effort of a large number of capable and motivated scientists to build the experiment, to make it running, to maintain it, to collect and analyze the data. Our measuring devices are very expensive, constructing the detectors often involves a large scale civil engineering effort and making the data analysis possible requires a collaboration among a number of research groups.
Since 2002, my main research efforts are with the ATLAS experiment, one of the experiments built for the Large Hadron Collider (LHC) at European Center for Nuclear Research (CERN, Geneva, Switzerland). One of our main goals with the LHC is to understand the origin of mass. My ultimate physics interests with the ATLAS experiment include the search for hypothetical heavy neutrinos and possible CP violation in their decays, new intermediate vector bosons, lepton, lepton-flavor and baryon number violating processes and direct signatures of supersymmetry, extra spatial dimensions and other not-yet discovered fundamental interactions at high energies.
To summarize, my current research interests include physics of
- Grand Unification and the Theory of Everything,
- Restoration of broken symmetries at high energies
- Leptoquarks, new vector bosons and heavy neutrinos
- Majorana neutrinos, neutrino masses, CP violation and baryogenesis
I am also very interested in
- Computational physics
- Electronics for energy measurements
- New data analysis techniques
- Outreach (I give public lectures and make presentations about the LHC and, in general, about particle physics in high schools)
Since 2004 four graduate students worked with me on the ATLAS experiment:
- Vikas Bansal (graduated in 2008, now a postdoc at the University of Victoria, British Columbia)
- Shanti Wendler (graduated in 2010, is now working at Consol Energy)
- Kevin O'Connell (is now working at a nuclear power plant in upstate NY)
- Reza Yoosoofmiya (graduation target date: Dec. 2012)
- It could be you, as I am currently hiring!
Over the past few years I have also collaborated with Damien Prieur, a research associate stationed at CERN. Damien is responsible for our part of the ATLAS detector at CERN, he contributed to my Majorana neutrino, WR, Leptoquark and Z' studies.
