I am an experimental physicist working on the ePIC experiment at the Electron-Ion Collider and the sPHENIX experiment at RHIC. I have worked on sPHENIX since its proposal in 2012, and before that I worked on its predecessor, PHENIX, from 1996 to 2016. I led the acquisition of the BaBar solenoid for sPHENIX, directed three beam tests of the calorimeters at Fermilab, served as sPHENIX Project Scientist during its construction, and was co-chair of the commissioning task force during the first year of operation in 2023.  In PHENIX, I held several leadership roles, including Deputy Project Manager, Data Acquisition Coordinator, Run Coordinator for Run 9 in 2009—the first RHIC run with polarized 500 GeV p+p collisions—and Deputy Operations Manager. I played a key role in the analysis of the parity-violating longitudinal single-spin asymmetries from the 2009 data.

My earlier work at Brookhaven, from 1986 to 1996, was on AGS Experiment 787, which made the first measurements of the branching ratios for the rare decays K+ → π+νν and K+ → π+μ+μ-, and pioneered the use of 500 MHz waveform digitizers in data acquisition and triggering.

I have worked on proposals for experiments at an Electron Ion Collider from ePHENIX and ECCE to ePIC.  I was appointed a Deputy Technical Coordinator for the ePIC collaboration in 2025.
