PhD candidate
Adobe Research Fellow
Computer Graphics Group
Columbia University


I am interested in acoustic simulation, virtual reality, and fabrication.


At Columbia, I am advised by Changxi Zheng. Over the past summer internships, I am fortunate to work with David Levin and Wojciech Matusik at Disney Research, and Timothy Langlois and Danny Kaufman at Adobe Research. During my undergraduate years at HKUST, I work with Chi-Keung Tang on image and video matting.

My research has been recognized by an Adobe Research Fellowship, a Shapeways Educational Grant, a NVIDIA PhD Fellowship Finalist, and an HKUST academic achievement medal.

As part of the perks from my research, I have used/maintained the following 3D printers. Formlab Form 1+, Makerbot Replicator 2 / Replicator Mini+, Stratasys uPrint SE Plus, Connex3 Objet350, Autodesk Ember, Eden 260VS, Ultimaker 2&3, and Othermill Pro.

I wrote some scripts to monitor our lab cluster.
I published a few 3D models online.
