About Me
I am a research scientist and manager at the Video Computer Vision org at Apple, based out of Seattle. I lead an applied research team, with a focus on neural rendering and generative AI for applications in Apple Vision Pro, iPhones, and other platforms. I did my Ph.D. at MIT and my undergrad at HKUST.
Shipped Products
I contributed to depth estimation on iPhone Pro, depth estimation on Vision Pro, face reconstruction for Persona (3D Facetime on Vision Pro), among others.
Research
I’m broadly interested in computer vision, machine learning, and computer graphics. Much of my research is about neural rendering, 3D reconstruction, and generative models.
