Biography
Background and Research Interests
My original training is in experimental particle physics, specializied in quantum calorimetry for neutrino and dark matter experiments at underground facilities. My current research includes:
-
High-precision nuclear decay measurements with cryogenic microcalorimeters, for probing physics beyond the Standard Model and advancing nuclear material analysis for nuclear safeguards and forensics applications.
-
Development of phonon-sensing quantum calorimeters for detecting neutrino and dark matter scattering.
Education
- Ph.D. in Physics, Seoul National University, 2016
- B.Ed. in Physics Education, Korea National University of Education, 2009
