Hello! I am an Experimental Particle Physicist working at Imperial College London and currently a member of the LHCb experiment.

The following are my current research interests:

Conducting new analysis in beauty flavour physics to measure the CKM matrix element related to the beauty-up quark.
Involved in the analysis of the performance of the LHCb RICH detectors.
Rare decays

I obtained my DPhil degree in Particle Physics from the University of Oxford in 2023, specializing in neutrino accelerator physics. I earned my bachelor’s and master’s degrees in Physics from the University of Manchester between 2015 and 2019.

The Deep Underground Neutrino Experiment (DUNE) utilizes Liquid Argon Time Projection Chamber (LArTPC) technology in its pursuit of uncovering the origins of matter. As a crucial prototype for the DUNE far detector (FD) module, ProtoDUNE-SP at CERN Neutrino Platform Facility employs a hadron test beam with a momentum range of 0.3 to 7 GeV/c to study the detector response to particles that could be produced in the neutrino interactions at the DUNE FD. Furthermore, ProtoDUNE-SP is dedicated to testing event reconstruction and performing detector calibration under controlled conditions. Neutral pion reconstruction performance is an important benchmark of the calorimetric and tracking capability of LArTPC, and understanding neutral pion in LArTPC is crucial to characterize backgrounds to oscillation measurements and rare searches. To improve neutral pion reconstruction in LArTPC, a kinematic fitting algorithm is developed, achieving a 12% resolution in neutral pion energy in ProtoDUNE-SP. This enhancement enables the first measurements of the pion-argon charge exchange differential cross-section. By com- paring these results with the current model, valuable constraints can be made to improve generator simulations in the future DUNE experiment.
