Patrick Cheong

About

Patrick completed his Ph.D. in Physics at the Chinese University of Hong Kong in 2021 where he was supervised by Prof. Tjonnie G. F. Li. As a N3AS fellow, Patrick stations at the University of New Hampshire with Prof. Francois Foucart as the faculty host.

Patrick’s research has been focused on general-relativistic simulation codes development, and their application to investigating neutron star astrophysics problems. Within the N3AS network, Patrick will primarily work on numerical modellings of highly magnetized neutron stars, neutron star mergers and core-collapse supernovae.
