Sang-Hyun Lim received his PhD degree in Physical Chemistry at the University of Illinois at Urbana-Champaign in 2003. He then pursued a postdoctoral fellowship at the University of California, Berkeley under the supervision of Stephen R. Leone. In 2006, he joined the faculty at the University of Texas, Austin. The focus of his group is developments of new optical imaging and micro-spectroscopy techniques to study complex chemical processes in biological and material systems. Of particular interest is CARS (coherent anti-Stokes Raman scattering) microscopy, which can map out chemical compositions and transformations in samples without any labeling. His group is pushing the sensitivity and selectivity limits of CARS microscopy and applying it to study composition and distribution of lipids in cells.
