Bowei Zhang is a fourth-year PhD student at the University of Cambridge, working under the supervision of Professor Paul Shellard. His research focuses on the interface between theoretical developments and observational probes of primordial non-Gaussianity. In particular, He is interested in the phenomenology of non-Gaussian signals arising from cosmological collider physics and the open effective field theory of inflation, using both analytical and numerical approaches. He also aim to confront these theoretical predictions with observations of the CMB and LSS.
