Welcome!

I’m a postdoctoral fellow at the Deutsches Elektronen-Synchrotron DESY (Zeuthen campus, near Berlin). I’m interested in theoretical multi-messenger astrophysics and astroparticle physics.

I joined Dr. Walter Winter’s group at DESY in October 2022. In August 2022, I obtained my PhD in Physics at Penn State University, where I was mentored by Prof. Péter Mészáros and Prof. Kohta Murase. Before that, I received my B.Sc. degree in Astronomy from Nanjing University in China.

My research focuses on the theoretical and numerical multi-messenger astrophysics, including the origins and implications of high-energy photons, cosmic rays, and neutrinos from individual cosmic sources and source populations. In particular, I model the acceleration, transport, and radiation processes of high-energy particles originating from tidal disruption events (TDEs), compact binary pairs (supermassive/stellar mass black holes), supernovae, gamma-ray bursts (GRBs), active galactic nuclei (AGNs), and galaxy/cluster mergers. I am interested in how the multi-messenger analyses enlighten our understanding of the physical nature of high-energy astrophysical phenomena.
