Bio
I am a theoretical particle physicist working mainly on physics beyond the Standard Model.
My research has focused on possible extensions of the Standard Model through neutrino physics and Higgs physics. In particular, I have studied right-handed neutrino models, Higgs phenomenology, and two-Higgs-doublet models, with an emphasis on how new physics can be constrained or explored through theoretical consistency, precision observables, and collider data.
In my work on Higgs physics, I have investigated extended Higgs sectors using electroweak precision constraints, Higgs signal strengths, and global fits. These studies aim to clarify how current and future experiments can test physics beyond the Standard Model.
At WPI-SKCM², my research interests are expanding toward quark–gluon plasma phenomenology and hot and dense QCD matter. I am particularly interested in how the properties and possible internal structures of QCD matter can be probed through particle correlations and femtoscopy. Through these research directions, I aim to connect theoretical ideas about fundamental particles and matter under extreme conditions with experimentally accessible observables.

What I like about my science
What I like most about physics is that it gives us a way to look at the world across extremely different scales, from the microscopic world inside atomic nuclei to the early universe. In theoretical particle physics, one can ask what matter is made of, what laws govern it, and how those laws can be tested through experiments. I find it fascinating that abstract theoretical ideas can eventually be connected to measurable signals. For me, the joy of science lies in exploring what is not yet known, understanding more deeply what is already known, and testing our understanding through the dialogue between theory and experiment.
