I am a doctoral student in the Department of Astronomy & Astrophysics at University of Toronto. I have received my bachelor degree at USTC in 2018. I was born in Shanghai, a city with vitality and glamour.

My supervisor is Roberto Abraham. I use the Dragonfly Telephoto Array to study the faint diffuse universe. My research is focused on controlling the systematic in the sky background of deep wide-field images to facilitate our understanding of the low surface brightness universe. My work mainly concerns the modeling of the wide-angle Point Spread Function, the sky background modeling at low surface brightness levels, pipeline development of the Dragonfly UltraWide (UW) Survey (with the Yale group) and dealing with the 'contaminant light' from the optical Galactic cirrus (with Peter Martin at CITA).

Before working on Dragonfly, I used SITELLE, an imaging Fourier transform spectrometer (IFTS) equipped at CFHT to study emission-line galaxies in galaxy clusters at z~0.25.

My name is homophonic in Chinese to the first & last characters of the famous sentence "留取丹心照汗青" from an ancient poem, which means "To illuminate the history".
