I will be working on searches for new physics with 13TeV data, in particular new dark sector models with long-lived particles that give displaced leptons or photons. I will also be working on detector upgrade studies for the High-Luminosity LHC (HL-LHC), including design optimization for the pixel detector, new physics with fast timing, and new physics in the forward region. I hope to combine current data analysis, upgrade simulation studies, and collaboration with theorists, to help map new territories for future dark matter searches at collider.
I joined CMS in the beginning of 2016 after completing my PhD on the other side of the LHC ring with the ATLAS experiment. I have played a leading role in simulation studies for the CMS pixel detector upgrade at HL-LHC, from setting up the simulation and validation tools, to performance studies and optimization. I co-manage the dark matter working group at Fermilab's LHC Physics Center, and coordinate the trigger and upgrade group in the LHC Long-Lived Particles Community. In close collaboration with theorists, I have introduced several new dark sector models to collider searches, and am studying them both in current data analysis, and for future upgrade projections.
