Professor of Physics, Florida State University
I do research in particle physics, also known as high energy physics. The goal is to understand the most basic particles and forces in nature. I work with the FSU High Energy Physics Group on the CMS Experiment at CERN and previously on the D0 Experiment at Fermilab. My focus is on searches for new physics in underexplored parts of the data sets. On CMS, I work on the electromagnetic calorimeter (ECAL), study possible calorimeter upgrades for 2023, and a search for diphoton resonances in triphoton events. A former graduate student, Venkatesh Veeraraghavan, and I worked on a search for heavy, stable, charged particles (HSCPs) that was published in JHEP, in PLB, and again in JHEP. This result was highlighted as Fermilab's Frontier Result of the Week on July 12, 2013. On D0, I have performed a search for a neutral, long-lived particle decaying to two muons that was included in Fermilab's Result of the Week on March 2, 2006 and published in PRL My former student, Haryo Sumowidagdo, and I have also studied top decays involving a tau lepton using the D0 detector. This work has contributed to several papers: top cross section and mass in dileptons (Phys. Lett. B), top cross section and charged Higgs interpretations (Phys. Rev. D), and search for charged Higgs in top quark decays (Phys. Lett. B). This work was also highlighted as Fermilab's Result of the Week on October 23, 2008.

Ten years! Ten years since the start of operations for the Large Hadron Collider (LHC), one of the most complex machines ever created. The LHC is the worlds largest particle accelerator, buried 100 meters under the French...
