My research focus is data analysis at the Compact Muon Soleniod (CMS) experiment at the Large Hadron Collider (LHC) at CERN.
The LHC is colliding protons at the highest energies ever reached with accelerators- a new energy scale that opens up the exciting possibility of great scientific discoveries. Explanations for the origin of electroweak symmetry breaking, the existence of dark matter, and the discovery of supersymmetric particles are finally within our reach. The discovery of the Higgs boson has been a major milestone for our field, and new phenomena, such as signatures of processes involving dark matter, could appear soon, as we are integrating data and are gaining sensitivity rapidly. More details about my current work, all our ongoing analysis groups, and how to learn more about Physics at the LHC can be found here:
In addition to my work on data analysis and detector commissioning, I work on detector upgrades for the LHC, in particular the upgrades of the innermost layers of the pixelated Silicon detectors, which have to withstand enormous doses of radiation. Our sensitivity to New Physics depends critically on our ability to track particles with very high precision in a very challenging environment.
Research work in my group involves development of data analysis algorithms and Monte Carlo simulation of New Physics phenomena expected to be observed at the LHC, detector operations and upgrades, as well as detector RD of novel silicon pixel devices. After an initial learning phase at Cornell, students usually travel to or live at CERN, Switzerland, for detector commissioning, data taking and years of exciting new physics discoveries.
