Junseo Lee
Update: I will be joining Harvard University in Fall 2026 as a PhD student in Quantum Science and Engineering, where I am fortunate to be co-advised by Anurag Anshu, Sitan Chen, and Jordan Cotler. I will also be affiliated with the Harvard Quantum Initiative and the Theory of Computation Group.
I am currently a Research Fellow at the Institute of Computer Technology, Seoul National University (SNU), supported by NRF, IITP, and ETRI.
My research focuses on the mathematical and theoretical computer science aspects of quantum systems, particularly quantum learning theory and quantum complexity theory, as well as their connections to quantum many-body physics.
Previously, I completed my mandatory military service in South Korea as a Technical Research Personnel, during which I was a Research Affiliate at the Research Institute of Mathematics, SNU. I received my B.S. in Electrical and Electronic Engineering from Yonsei University, where I was supported by the Hyundai Motor CMK Science and Technology Scholarship.

Mentoring +
During my time as a Research Fellow and Research Affiliate at Seoul National University, I mentored undergraduate students in research. It was a great privilege and a deeply rewarding experience to work with such talented students, and I learned a great deal from our collaborations as well.
- Myeongjin Shin (Spring 2023–present, co-supervised with Kabgyun Jeong)
- Mingyu Lee (Spring 2024–present, co-supervised with Sathya Subramanian)
- Donghwa Ji (Spring 2025–present, co-supervised with Kabgyun Jeong)
- Kartik Anand (Summer 2025)
Miscellaneous +
I enjoy playing table tennis and piano, and I also like a wide variety of puzzle games.
I am also particularly interested in the Mathematics Genealogy Project. By tracing the academic lineages of my advisors, I came across several fascinating connections. In particular, it was striking to encounter figures such as Leonhard Euler (from Anurag Anshu), Carl Gustav Jacob Jacobi (from Sitan Chen), and Paul Dirac (from Jordan Cotler) along these lineages!
