James Olsen

James Olsen is a Professor of Physics and Department Chair at Princeton University. He holds a B.S. in Physics from University of California, Davis (no specific year noted) and a Ph.D. in experimental high-energy physics from University of Wisconsin–Madison (1998).

His research focuses on fundamental particle constituents like quarks and leptons, exploring flavor structure and generation hierarchies. Notable contributions include leading roles in Higgs boson discovery via CMS detector at CERN's LHC (2012), and CP violation studies using the BaBar detector at SLAC. He currently leads Princeton's Physics Department while maintaining active involvement in LHC and particle physics collaborations.

Awards include Sloan Research Fellowship (no year noted), Kavli Fellowship, and American Physical Society Fellowship.
