Educational Background: 
  • Ph. D. in Physics, University of Wisconsin Madison, 2012
  • M. Sc. in Physics, National Technical University of Athens, 2007
  • B. Sc. in Applied Mathematics and Physics, National Technical University of Athens, 2005
Research Interest: 

My research interest is focused in the energy frontier of particle physics where  along with my other UCLA colleagues, I participate in the Compact Muon Solenoid (CMS) experiment at CERN’s Large Hadron Collider.

In the first LHC run, I played a leading role in the discovery and characterization of the Higgs boson through its Z boson and tau decays.
My current projects involve searches for heavy new particles at the highest TeV energy collisions of the LHC. Possible discovery of those particles could reveal new fundamental interactions, additional Higgs bosons  or more exotic scenarios such as extra dimensions.

In addition to data analysis, I am working on a custom electronics system  known as the CMS trigger where we use FPGAs  to identify charged particles known as muons and measure their  momentum  in real time LHC collisions at a rate of 40 MHz.
