Bio

I am a third-year PhD student at UT Austin, where I am advised by Scott Aaronson and supported by an NSF Graduate Research Fellowship. My research interests are in complexity theory and quantum information. Previously, I was an undergraduate studying EECS at UC Berkeley, where I was incredibly fortunate to be advised by Avishay Tal and Prasad Raghavendra. During the summer of 2023, I was an intern at Sandia National Laboratories mentored by Ojas Parekh. For more details, you can find my CV here.

Outside of my academics, I am interested in nature, tennis, basketball, and gaming. I am also very passionate about civil rights and environmental issues. During my free time, you can find me playing basketball/tennis, gaming, and rooting for Steph Curry and the Golden State Warriors.

In Spring 2024, I will be a long-term participant at the Simons Institute program on Quantum Algorithms, Complexity, and Fault Tolerance.



Research Overview

I am broadly interested in quantum information and complexity theory. Concretely, some topics of my research include:

Teaching

I am keenly interested in teaching computer science and have served on course staff for 8 different course offerings:

UT Austin: UC Berkeley:
In 2019, I received the Oustanding GSI award from the UC Berkeley Graduate Division, for which I am incredibly grateful to my students and mentors. My full evaluations at UC Berkeley can be found here.

Service

I believe that my role as an academic involves service. As an undergraduate, I served on the EECS Undergraduate Study Committee (UGSC), interfacing with professors to address issues such as elitism and discrimination. In addition, I worked with the department to design, administer, and analyze the annual undergraduate experience survey. My work in this area helped facilitate a number of reforms, including the EE/CS community week and calls for culture change within EECS extracurricular groups.

I am a volunteer with Texas Prison Education Initiative, where I teach UT Austin's precalculus course to inmates.
