 I completed my B.S. and M.S. degrees in Chemical Engineering at the University of Southern California, where I conducted undergraduate research in computational catalysis under the mentorship of Professor Shaama Sharada. During my time at USC, I served as a summer R&D intern with ExxonMobil where I developed computational tools to automate the modeling and design of heat-exchanger equipment. Prior to joining MIT, I spent a gap year working full-time as an Operations Engineer at SpaceX optimizing spacecraft production.
 
 Outside of research, I enjoy concerts, playing music, movies, baseball, and Formula 1.
