Hanke Chen

CMU(2020) -> Midjourney(2023) -> CMU(2026) | Ugrad @CMU(CS+Art)_

I am Hanke （瀚可） Chen （陈） , an undergraduate student at Carnegie Mellon University persuing Computer Science and Art. Currently, I am working on Katzuki (Artists' Tool for 3D Creation). Also part of SIG@CMU adviced by Prof. Minchen Li. Before this, I do R&D for Midjourney and research for WiSELab@CMU advised by Prof. Anthony Rowe and Tianshu Huang.

I make music, games, and products. I'm arguably the leading authority on open-vocab Minecraft structure generation. I used to compete in Kaggle and FTC in high school. I used to own a RPG game played by 300,000+ players. Switch off my sanity on the top left to find out more.

Research

Artists sell ideas. The best artists are researchers. I do whatever it takes to get things done and NOT STUCK IN ONE FIELD. I am 80% an engineer and 20% an artist, which means MY RESEARCH IS USUALLY PRODUCT-ORIENTED.

Current Research interests: make tools for artists, which often involve NeRF / 3D Reconstruction -> Diffusion / 3D Generation
