Jingtao You is a PhD student at the School of Physics and Astronomy, Shanghai Jiao Tong University (SJTU). His research interests include inflation, primordial cosmology, and their connections to particle physics. His work focuses on using the early Universe—particularly primordial non-Gaussianity and cosmological collider signals—as a probe of physics beyond the Standard Model, including phenomena associated with the Higgs sector and the seesaw mechanism.
