Jae Hwan Kang

Jae Hwan Kang is a Research Fellow in the Department of Physics at the California Institute of Technology, affiliated with the Division of Physics, Mathematics, and Astronomy. His work focuses on experimental cosmology, particularly on measuring cosmic microwave background (CMB) polarization using the BICEP/Keck and BICEP Array experiments. He specializes in detector development, calibration techniques, and data analysis for large-scale CMB observatories. His research addresses questions about primordial gravitational waves, cosmic inflation, and foreground contamination in CMB signals.

Key projects include the BICEP Array's 150 GHz detector modules, polarization calibration of the BICEP3 instrument at the South Pole, and analysis of cosmic birefringence effects. Kang's contributions span instrumentation design (e.g., antireflective coatings, multiplexing systems) and theoretical interpretation of observational data. He participates in international collaborations like the CMB-S4 initiative, aiming to advance next-generation cosmological surveys.
