I am a first-year Ph.D. student in Computer Science at Northwestern University, advised by Prof. Emma Alexander. Previously, I received my B.Eng. in Electronic Engineering with a minor in Astronomy at Tsinghua University magna cum laude. During my undergraduate study, I was fortunate to work with Prof. Lu Fang, Prof. Emma Alexander, and Prof. Cheng Ma. My research interest is in the field of computational imaging, which lies at the intersection of optics, signal processing, computer vision, computer graphics, and machine learning. Specifically, I enjoy solving inverse problems using domain-specific knowledge (e.g., optics and geometry) in computational photography, astronomical imaging, and biomedical imaging.

    Outside of research, I enjoy playing basketball and amateur astronomy. I spent four wonderful years at the Tsinghua Astronomy Society as a core member. I'm also a huge fan of the Golden State Warriors 🏆🏆🏆🏆 and the HARRY POTTER series.

    Here is a collection of my course projects.
