I am interested in acoustic simulation, mixed reality, and computational fabrication.

Research

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, an ACM UIST Best Paper Award, a Shapeways Educational Grant, a NVIDIA PhD Fellowship Finalist, and an HKUST academic achievement medal.



Since 2016, I have been volunteering as a superuser at Columbia Makerspace to teach and train new users on fabrication-related tools. In my research and personal projects, I have used/maintained the following digital fabrication tools, including 3D printers, laser cutters, and milling machines: Autodesk Ember, Eden 260VS, Stratasys uPrint SE Plus, Formlab Form 1+, Makerbot Replicator, Connex3 Objet350, Ultimaker 2&3, Othermill Pro, Silhouette CAMEO Cutter, VLS3.50, and Thunder Laser Nova.
