I am a professor of physics and the current chair of the Department of Physics, University of Wisconsin.
My research work is conducted with the UW High Energy Physics group, on the CMS experiment at the CERN laboratory in Geneva, Switzerland and the LZ experiment in South Dakota. My scientific interest is in the study of elementary particles, to probe unresolved questions about the current standard theory of matter and energy, and enable an even deeper level of knowledge about fundamental interactions in nature.
The physics adventure of CMS continues after the discovery of the long sought Higgs boson, in which my group played an important role. The study of highest energy collisions protons created using LHC will thoroughly map out the Standard Model of particle physics, including detailed study of the properties of the Higgs boson. With the LHC resuming data taking in 2015 at unprecedented 13 TeV center of mass energy, the focus is on search for new physics processes, including search for an elementary particle candidate that can explain the dark matter, which makes up the bulk of our Universe.
The LZ experiment is in design phase and will be installed in a deep mine in South Dakota. This liquid Xenon time-projection chamber will search for very weak signatures of dark matter interactions with Xenon atoms.
In the previous decade, I worked on the BaBar experiment at the SLAC laboratory in Stanford, California, where we studied short lived particles called B-mesons that were produced profusely in electron-positron collisions at the SLAC B-Factory. Our measurements there resulted in detailed understanding of asymmetries between matter and antimatter behavior and placed strict limits on the level of new physics contributions to flavor physics.
Further in the past, I participated in ZEUS and SLAC fixed target experiments, which measured proton structure and other strong interaction physics, and in SLD experiment which made precision measurements of the Standard Model parameters.
My day-to-day work involves teaching, supervision of students, postdocs and staff, physics data analysis, large scale computating systems design and operation, low and high level trigger algorithm development, detector simulations and trigger electronics design, and lately administration duties of the physics department. In addition to the work at the CMS experiment in Geneva, my group operates a large computing center, UW Tier-2, in Madison for the benefit of CMS physics community.
