What I will be working on:

I will extend my studies of events containing muons + MET + jets + b-jets in the final state to obtain a well understood top quark pair sample which can be further used to study the properties of top quarks in detail. With increased luminosity, the sample will also be used to measure the rate at which the two light jets in ttbarjj events are mis-identified as b jets, a process that represents the main irreducible background to ttbar-Higgs production. The sample can also be used to look for BSM processes with the muons, MET and b-jets in the final state.

My role in CMS past and present:

I joined CMS in 2001, and over time, contributed to several activities related to the Silicon Tracker: R&D, construction and commissioning of the Tracker Outer Barrel, cosmic data analysis and software development, and more recently, R&D of the phase I pixel upgrade. I served as co-leader of the Fermilab LHC Physics Center (LPC) group that studies the identification of jets originating from b-quarks from 2006 to 2009, developing methods to measure the performance of the b-tagging algorithms using events containing muons within jets. For the 2010 data analysis, I contributed to the measurement of the top quark pair production cross section using events with a high pT isolated muon, missing transverse energy, and at least three jets, of which at least one is tagged as a b-quark.
