Ue-Li Pen Research Interests

This research focuses on advanced studies in cosmology and large-scale structure, specifically cosmic reionization and the dynamics of dark energy and matter, explored through techniques like gravitational lensing and baryon acoustic oscillations (BAO). Additionally, we investigate magnetohydrodynamics (MHD) in non-radiative accretion flows using MRI tools, and 21cm data from GMRT. Collaborating with top researchers, we leverage high-performance computing resources, including a new initiative that enhances computing capabilities at the University of Toronto.
