About

Jinwoo Hwang received his Ph.D. from the University of Wisconsin, Madison in 2011. He has been a postdoctoral researcher at the University of California, Santa Barbara for 3 years. His research interests include advanced structural characterization of materials, S/TEM technique development, and computational materials modeling. In particular, he has developed novel S/TEM techniques and simulation methods based on electron nanodiffraction and quantitative imaging, for nanostructured materials, oxide heterostructures, and non-crystalline materials. For his contributions to the field, he has received several honors and awards, including The Albert Crewe award from the Microscopy Society of America in 2014.
