Hi, I’m Joon. I’m a rising fourth year student at the University of Virginia, pursuing a double major in computer science and mathematics. I’m a member of RAISE group at UVA, led by Prof. Ferdinando Fioretto. For summer 2025, I’m working as a research intern at Carnegie Mellon University’s School of Computer Science, advised by Prof. Steven Wu.

My research interests lie in algorithmic fairness, differential privacy, optimization, and uncertainty quantification. Broadly, I’m interested in the societal impact of AI, particularly in high-stakes decision-making settings. Fun fact: my Erdős number is 3.

I’m applying to Ph.D. programs in the upcoming cycle!
