Dr Christopher Pollard

BS Yale, PhD Duke


Chris is a Stipendiary Lecturer at St Hilda's College and a postdoctoral researcher in the Department of Physics' ATLAS group. He teaches Physics to second- and third-year undergraduate students.


Chris studied at Yale University and performed his graduate work at Duke University with Ashutosh Kotwal. He has since held positions at the University of Glasgow and DESY.

Chris is performing measurements of Standard Model (SM) processes as well as searches for beyond-SM interactions using LHC collision data collected with the ATLAS detector. His recent focus has been developing algorithms to experimentally reconstruct complex hadronic decay chains, including for real-time reconstruction in the ATLAS trigger systems. These techniques are critical to experimentally test the SM predictions of lepton flavor universality and the dynamics of the Higgs field potential, his current interests.
