I recently earned my PhD in Materials Science and Engineering from The University of Texas at Austin, where I worked in the computational materials lab of Dr. Gyeong Hwang. My research interests lie largely in using data-driven approaches to understand and predict nonequilibrium chemical processes that occur during plasma processing of semiconductor materials.

Previously, I did my undergrad at UC Berkeley, where I obtained a B.S. in Chemistry. At Berkeley, I was an undergraduate researcher in the Saykally group , where I researched the evaporation of aqueous solutions using Raman thermometry. I also developed a keen interest in data science, and was involved in multiple projects through the Berkeley Institute of Data Science . For three semesters (Sp17-Sp18), I was also on course staff for Foundations of Data Science.

In my spare time, I speedcube, boulder, and play Tetris.

You can find a copy of my (possibly) up-to-date CV here.
