What I will be working on:

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.

My role in CMS past and present:

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.
