My name is Tim and I am a research scientist at OpenAI. I aspire to use technology to enable people to create anything they imagine. My current research investigates large-scale AI models for generating user-controlled visual content.
I recently wrapped up a PhD at Berkeley AI Research advised by Alyosha Efros. I previously worked at Google on machine learning in the Pixel smartphone camera and at NVIDIA on video generation models. I am fortunate to have collaborated closely with Tero Karras, Ming-Yu Liu, Jon Barron, and Marc Levoy.
This website contains some of my original individual and collaborative works. My photography has landed awards from National Geographic, Nature's Best Photography and National Wildlife Federation. I have performed at the Beacon Theatre on Broadway in New York City and have received an international award for a cappella beatboxing.
I am passionate about my career in computer science and artificial intelligence, and fortunate that it melds with my love for photography, film, and music. I welcome your comments and questions about my work.
