Bruce W. Lee

I'm a CS student at UPenn. I work on making intelligent systems smarter and, more broadly, understanding and aligning them. I see these as fundamentally connected rather than in tension. It's an ambitious research direction, which is why I emphasize building good tools. My open-source libraries are now used across several research labs.

I hope my work can help expand human possibilities and productivity for long-term prosperity. Outside of research, I row for my college varsity team and served in the Marine Corps.
