What I will be working on:

I will be working on searches for new physics, especially new dark sector models with long-lived particles. I will also be working on detector upgrade studies for the High-Luminosity LHC (HL-LHC), including design optimization for the pixel detector, and physics performance studies for the timing detector and high-granularity calorimeter. I hope to combine current data analysis, upgrade simulation studies, and collaboration with theorists, to help define new benchmarks for future dark sector searches at CMS.

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. In close collaboration with theorists, I have introduced new dark sector models to collider searches, and am studying them both in current data analysis, and for upgrade projections.
