Professor Hua FENG conducts research in high energy astrophysics, mainly interested in space astronomy and understanding accretion onto black holes and neutron stars. He is dedicated in developing next-generation detection technologies for X-ray and gamma-ray astronomy, such as X-ray polarimetry and high spectral resolution MeV emission line measurement.

He has led small scale space projects like PolarLight. He tries to understand the physical processes in supercritical accretion by means of multiwavelength observations and theoretical analysis, as well as feedback into the interstellar medium and larger scales due to radiation and outflows driven by supercritical accretion.
