Hi, I’m Joon. I’m a 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. I spent summer 2025 as a research intern at Carnegie Mellon University’s School of Computer Science, advised by Prof. Steven Wu, and I am continuing the project remotely.

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!
