What I will be working on:

I will perform a stealth SUSY search with top quarks in the final state for low-MET signals. I will be mainly focusing on top squark pair production in stealth SUSY models, in which the top squark decays into a top quark and singlino. By benefiting from my group's expertise on top quark tagging, we hope to explore a large parameter space currently left unexplored. In addition, I plan to consider signatures expected from a R-parity violating (RPV) SUSY model. This leads to a similar final state as expected from the stealth SUSY model. Limits for such a model are very weak at present, and it will be very interesting to explore this possible signature.

My role in CMS past and present:

I started my graduate studies at Baylor in August 2015 and my research work with the CMS experiment in the summer of 2017. I have worked on various projects related to the Hadron Calorimeter (HCAL) including the tuning of time slew in simulation, corrections to the pulse shape for scintillator + wavelength-shifting fibers in CMSSW, taking and analyzing HCAL endcap (HE) & barrel (HB) test beam data, and testing/updating the HE Phase 1 calibration unit. I also have plans to help with the installation of the HE Phase 1 readout electronics and play a significant role in the testing of the charge integrator and encoder (QIE) cards for the HB Phase 1 front-end electronics, which will take place in summer of 2018.
