Assistant Professor and Computational Astrophysicist

I am an assistant professor at the Chinese University of Hong Kong, working on astrophysical simulations of the Universe, stars, galaxies, and dark matter.

I was an Inaugural Margaret Burbidge Fellow at the University of Chicago, focusing on cosmological galaxy simulations and radiative transfer. I was a post-doctoral research associate at the Institute of Computation Cosmology, Durham University, working with Tom Theuns, Richard Bower, and Carlos Frenk on galaxy simulations. We have recently developed a novel radiative transfer method paper on MNRAS, which will have many potential applications in galaxy simulations. Our module is publicly available on SWIFT and we welcome any suggestions and collaborations.

I was a physics graduate student at the University of California, San Diego, working with Dusan Keres. We are part of the Feedback In Realistic Environment (FIRE) collaboration, which focuses on high-resolution cosmological simulations with comprehensive stellar feedback.

During my master degree, I worked on gravitational waves and the properties of compact objects with Professor PT Leung in the Chinese University of Hong Kong.

I specialize in numerical methods, parallel computing (C, Fortran, and MPI), and data analysis (Python).

Radiative Transfer

Simulating radiation propagation is important for stars, galaxies, and cosmology. We developed a novel radiative transfer method that treats radiation as a fluid. See the method paper in MNRAS (arXiv).

Dark Matter

Dark Matter is invisible matter but it provides strong gravity to hold galaxies. We show galaxies can also shape the dark matter distribution through outflows and contraction. (more…)

Cosmological Simulations

Cosmological simulation is to model the cosmic structure formation from the beginning of the universe. I am a member of the Virgo Consortium and FIRE collaboration, which perform state-of-the-art cosmological simulations.

Cosmic Ray feedback

Cosmic rays are highly energetic charged particles. They can regulate gas flows and star formation in galaxies. We constrain their propagation with γ ray observations. (more…)

Oscillations of Compact Stars

Compact stars, e.g. neutral stars, can oscillate at high frequencies. Some of the oscillations can generate gravitational waves. By analysing these oscillations, we can understand the structures of compact stars. (more…)

Ultra Diffuse Galaxies

Ultra diffuse galaxies are extended and dim galaxies with mysterious origins. We explain their origins with strong outflows and quenching at early times. (more…)
