What's Up

I'm an EECS Masters student at MIT, where I'm grateful to be advised by Max Tegmark. I'm primarily interested in AI Safety from two angles: mechanistic interpretability, where I attempt to decode the underlying algorithms neural networks use, and alignment, where I explore how to control and align AI systems with human values. Recently, I was accepted to do an EECS PhD at U.C. Berkeley

I received my undergraduate degree from MIT with a double major in Physics and Computer Science and a 5.0 GPA. During this time I won the Fulbright Scholarship, was accepted to MIT's Physics honor society in the top 10% of physics majors, advised MIT President Sally Kornbluth through the Presidential Advisory Cabinet, and taught STEM workshops to high school students in South Korea, South Africa, Botswana, and Bahrain. I love reading, meditating, traveling, and playing basketball (go Heat).
