Wonsuk Cha has been working on Coherent X-ray Diffraction Imaging in Bragg geometery (BCDI). He joined the staff of the Advanced Photon Source, Argonne National Laboratory in 2016.

His primary research interest is in discovering the relationship between structure and property using and developing new coherent x-ray diffraction techniques including BCDI. He is also working on utilizing broadband coherent x-rays for fast measurements for BCDI. His another research interest is developing new instruments for in-situ catalysis or phase transition experiments.
