Experimental High Energy Physics: The ATLAS Collaboration at CERN
(Inside ATLAS with Dr. Michael Strauss and fellow Ph.D. student Ben Pearson)
Analysis
2014-Present: Measurement of top quark pair production with a veto on additional central jet activity in proton-proton collisions at 8 TeV center-of-mass energy using the ATLAS detector. Primary analyst under the supervision of Dr. Michael Strauss (OU) and Dr. Richard Hawkings (CERN). In review for publication by the ATLAS Collaboration.
2013-2014: Determination of the top quark pole mass from the top quark pair production cross section at 7-8 TeV center-of-mass energy using full NNLO+NNLL predictions. Primary analyst under supervision of Dr. Michael Strauss (OU) and Dr. Richard Hawkings (CERN). Publication in JHEP 2014.
Detector Development
2014-Present: Inner Detector monitoring shifts in the ATLAS Control Room
2012-2013: Simulation of irradiation effects in the ATLAS Pixel Detector. Under the supervision of Dr. Philippe Grenier (SLAC) in the ATLAS Offline Software Group and Dr. Michael Strauss (OU).
