I'm currently a PhD student in physics at Caltech, where I'm fortunate to be co-advised by John Preskill and Fernando Brandão. I completed my bachelor's in physics and math at MIT in 2023.

I'm broadly interested in the intersection of information theory and quantum many-body physics, particularly in ways of characterizing quantum complexity.

In addition, I am committed to increasing access to opportunities in STEM, particularly for students from nontraditional backgrounds. I previously served on the MIT Physics Values Committee and worked on writing curriculum for students without prior experience in proof-based mathematics.
