Department of Physics, Graduate School of Science
I’m an international student from Sri Lanka, majoring in high energy physics, and a member of the Yamanaka group of the department of physics. I like learning and experiencing new things, and hence, my hobbies and interests span over many activities; some of my recent hobbies are aqua-scaping, gardening, graphic & web designing, and baking.
Currently, I’m a part of the ATLAS collaboration based in CERN, which uses the ATLAS detector (located at one of the proton-proton collision points of the LHC). We use the ATLAS detector to study the one and only Higgs boson, and my interest in particular is about the coupling of the Higgs boson to the Charm quarks. Although this process is extremely difficult to probe in a hadron collider (like LHC), new techniques which utilize deep learning allows us to search for Higgs to charm quark signals with more sensitivity than previously thought. Hence, my current research involves in developing deep learning models for the Higgs to charm quark analysis, and we hope to provide the world’s best measurement of Higgs to charm quark coupling in the near future.
Along with this analysis work, I am also engaged in the development of software tools for monitoring the current ATLAS semiconductor strip detector sub-system, while aiding in operations to get the ATLAS detector ready for the Run-3 of the LHC. Also, during my masters I was involved in developing new silicon pixel detectors for upgrading the ATLAS detector for the future HL-LHC Run-4 (LHC will be upgraded to HL-LHC by 2029).
Thanks to such research projects, I believe I gained a lot of knowledge in various fields, and a diverse set of technical skills. My goal is one day to use this knowledge and skills to contribute to society by tackling major issues (like climate change) we’re facing right now.
