I’ve spent most of my life on understanding the foundations of the physical world.
I’ll spend the rest on how models think and how to make them better and safer.
Starting early Sept. 2025, I’m an interpretability researcher at CHAI/BAIR with Cam Allen.
I’m also a 4th-year physics major at Berkeley.
Until late Aug. 2025, I was a particle physics researcher at the Neutrino Group at SLAC under Professor Hirohisa Tanaka. I used latent spaces to investigate the low-energy excess of electron neutrinos detected in the MiniBooNE experiment.
Before SLAC, I worked on Bayesian analysis for Mu2e under Professor Yury Kolomensky.
Before Berkeley, I wanted to experience “real life” – so I went all in and took a half a year to work as a trash man. Then I went to South America for a half a year. Things like the deadly fear I felt when running from wild dogs in the desert gave me clarity on what matters in life.
I love language and spend more than half of my time speaking languages other than English (~ 30% Chinese, 30% English, 15% Spanish, 15% Swedish/Norwegian, 10% Italian)
My values have been influenced greatly by Marcus Aurelius’s Meditations, Confucius’s Lunyu ( 论语 ), and Noah Harari’s Homo sapiens. The most transformative read of my life was when I read Joanne Baker’s 50 Physics Ideas You Really Need to Know as a kid.
I believe that fundamental physics is an attempt at approximating the universe’s source code, and that AI will probably find it.1
This is exciting, and on this website, I will explore the basics of deep learning.

Footnotes
If new ideas are clever combinations of previous ideas, it seems that artificial neural networks will be the ones coming up with most new theories and inventions by virtue of their computational speed.
Even Einstein, arguably the smartest person ever, got special relativity by combining Galilean relativity, the absence of an ether (as implied by the recently conducted Michelson-Morley experiment), and a fixed speed of light as given by the solution to Maxwell’s equations. As far as I can tell, all new “idea vectors” are constructed from previous “idea vectors” in some fixed-dimensional space.↩︎
