I am a 5th-year Ph.D. student at the Computer Science department of the University of Southern California, where I am fortunate to be advised by Prof. Shaddin Dughmi and Prof. David Kempe.

My research focuses on online and combinatorial optimization under uncertainty and computational social choice, exploring how algorithms can make fair and smarter decisions in unpredictable and strategic environments.
