About

December 2024 – September 2025 — I started a company called Lucid with my friend, backed by Y Combinator (W25 Batch), Makers Fund, Samsung Next, and Amplify Partners. We built the fastest Minecraft world model at the time: 25 FPS on a 4090 using super-compression VAEs with only 15 tokens per frame. It was cited as one of two benchmarks in the DreamerV4 paper. I also worked on personalization with LoRA Diffusion.

August 2021 – December 2024 — I was a Computer Science undergraduate at UC Berkeley. Advised by Amir Bar and Trevor Darrell, we wrote a paper analyzing the in-context learning abilities of vision transformers: arXiv, GitHub, ECCV 2024, and ICML 2024 MI Workshop poster.
