Junseo Lee

I am an incoming PhD student in Quantum Science and Engineering at Harvard University, where I am fortunate to be advised by Professors Anurag Anshu, Sitan Chen, and Jordan Cotler.

At Harvard, I am affiliated with the Harvard Quantum Initiative, the Theory of Computation Group, and the Department of Physics. I am also a Junior Investigator at the NSF AI Institute for Artificial Intelligence and Fundamental Interactions (IAIFI), based at MIT.

My research lies at the intersection of theoretical computer science and mathematical physics, focusing on quantum complexity, quantum learning/sensing, and the computational foundations of quantum many-body systems.

Previously, I conducted research at Seoul National University through the Institute of Computer Technology and the Research Institute of Mathematics. I completed my undergraduate studies in electrical and electronic engineering at Yonsei University, fully supported by the Hyundai Motor CMK Science and Technology Scholarship.

Mentoring +

I mentored undergraduate students in research, which I found both deeply rewarding and intellectually enriching. I had the privilege of working with outstanding students and learned a great deal from our collaborations. The students I have worked with are listed below:

Current Mentees:
Former Mentees:
  • Kartik Anand (IIT Goa, 2025; now a master's student at Hamburg University of Technology)

I am happy to discuss potential research opportunities with undergraduate students, including summer projects. In some cases, projects may also develop into collaborations involving other researchers. Please feel free to reach out by email if you are interested!
