Jianhao WU-CS to Physics

I am currently a 2nd year MPhil student @CUHK Physics, under the supervision of Prof. Tsang Keung Chan. I am interested in the intersection between astrophysics and fundemental physics, especially using cosmological signals to study fundamental physics problems including early universe, dark matter and dark energy. I am now working on Milky-Way host size dark matter halo substructure simulation for a small scale enhanced primordial power spectrum (arxiv:2412.16072).

I got my Physics MSc degree also @CUHK in 2023, with CUHK MSc in Physics Excellent Performance Award. It complemented my knowledge gaps as a non-physics student, by covering Quantum Mechanics, Statistical Mechanics, Computational Physics, Cosmology, and etc.

I got my Computer Science BEng degree @WHU in 2022, where I determined the physical origin of North Polar Spur, a bright structure on radio band within Milky-Way, by synchrotron radiation calculation (Astronomy & Astrophysics 676, L3 [arxiv:2212.04306]). My supervisor and co-author was Prof. Guobin Mou.

Currently looking for 2025 Fall PhD position in cosmology:
