Biography and Interests
I am a first-year graduate student at the University of Wisconsin - Madison, working in the CMS group and advised by Professor Sridhara Dasu. This is my first year with the TAC-HEP project.
Project
I am contributing to developing a modern emulator for the CMS Hadron Forward (HF) Calorimeter section of the CMS Level-1 (L1) Trigger System that more closely matches actual hardware. The Large Hadron Collider (LHC) will be undergoing an upgrade into the High-Luminosity LHC, which will significantly increase the amount of data collected. As the frontline for event collection in the CMS Detector, the L1 Trigger System must also undergo several upgrades to increase its selection efficiency to handle this increase in luminosity. As upgrades commence, the trigger pipeline must be replicated in simulation to ensure cohesion with the upgraded physical firmware, to allow for comparison and debugging, and to explore new methods of selection within the trigger system. I am also exploring the deployment of machine learning models onto the RCT (Regional Calorimeter Trigger) and HF trigger sections (once emulator is completed) to optimize event selection and object reconstruction for the HL-LHC era.
