M.S. Researcher · IBS Center for Quantum Nanoscience · Seoul
I am an M.S. researcher at IBS Center for Quantum Nanoscience, Seoul, working on lanthanide atoms on surfaces as candidates for atomic-scale spin qubits. My work sits between experiment and theory. I build multiplet and crystal-field models in Quanty and fit them to XAS/XMCD and ESR-STM data with Bayesian optimization.
Alongside this, I participated in synchrotron x-ray absorption experiments including measurements of frustrated magnets, such as Co₁/₃TaS₂ and HoAgGe, and my interests have gradually broadened from single-atom qubits toward magnetism in quantum materials.
I also care about what happens outside the lab such as science outreach, philosophy of physics.
