Biography

I have been a member of the CDF collaboration since 2003 and of the CMS collaboration since 2014. Since 2024 I have been the Director of the Collider Physics Division and head of Fermilab CMS Group.

My research focus on CMS has been on searches for new physics and on computing infrastructure and services. My group has explored possible dark matter signatures, including those with long-lived particles, in Run 2 data and are focusing on long-lived particle signatures for Run 3 of the LHC. Previously, on the CDF experiment, I led measurements of the W boson mass and top quark mass, and led a search for the Higgs boson decaying to bottom quarks.

I obtained a PhD in physics from the University of Michigan (2006) and prior to working at Fermilab was a postdoctoral scholar at Duke University.
