Junseo Lee
I’m a first-year PhD student in Quantum Science and Engineering at Harvard University, where I am advised by Anurag Anshu, Sitan Chen, and Jordan Cotler. My doctoral studies are also supported by the Kwanjeong PhD Fellowship.
I am part of the Harvard Quantum Initiative and the Theory of Computation Group. I am also an NSF IAIFI Junior Investigator at MIT.
I am interested in the interplay between computational complexity and quantum physics, spanning foundational theoretical questions and applications in quantum information processing.
Previously, I was a research fellow at Seoul National University through the Institute of Computer Technology and the Research Institute of Mathematics.
I completed my B.S. at Yonsei University as a Hyundai Motor CMK Scholar.
