Yanjiao Ma is currently a second-year PhD student in the Department of Physics at The Hong Kong University of Science and Technology (HKUST), supported by the Hong Kong PhD Fellowship Scheme (HKPFS). She is conducting her research under the supervision of Professor Yi Wang. Her primary research interests lie in theoretical early universe cosmology. Specifically, her current work focuses on the calculation of cosmological correlators and the study of primordial non-Gaussianities. Prior to joining HKUST for my doctoral studies, she obtained her undergraduate degree from Shandong University.
