Junseo Lee
Update: I will be joining Harvard University in Fall 2026 as a PhD student in Quantum Science and Engineering, affiliated with the Harvard Quantum Initiative and the Theory of Computation Group.
I am a Research Fellow at the Institute of Computer Technology, Seoul National University, in a position supported by projects from NRF, IITP, and ETRI.
My research focuses on theoretical computer science questions concerning quantum systems, particularly quantum learning theory and quantum complexity theory, as well as related problems in theoretical physics and pure mathematics, including quantum gravity and quantum topology.
Previously, I completed my mandatory military service in South Korea as a Technical Research Personnel and was a Research Affiliate at the Research Institute of Mathematics, Seoul National University. Prior to that, as an undergraduate at Yonsei University, supported by the Hyundai Motor CMK Scholarship, I studied Electrical and Electronic Engineering and worked with Dr. Kabgyun Jeong as part of the Quantum Information Theory Group at the Research Institute of Mathematics, Seoul National University.
