About me:
My research focuses on theoretical high energy physics and cosmology, with a particular interest in supergravity, string theory, and extra-dimensional phenomenology. Currently, my work extends to exploring the intersections of theoretical models and cutting-edge particle physics, specifically through my active participation in the KATRIN and JUNO collaborations. Through these joint efforts, we aim to probe the fundamental properties of neutrinos and test new physics beyond the Standard Model—such as the implications of the Dark Dimension—by bridging high-energy theoretical frameworks with precision experimental data.
Our joint work on the Dark Dimension and KATRIN experiment with Ignatios Antoniadis and Hiroshi Isono has also gained broader public interest, featured in Popular Mechanics (available here).
