Abstract: Recent advances in super-resolution fluorescence microscopy have led to ~10 nm spatial resolution and exciting new biology. We are developing new approaches to advance beyond the structural (shape) information offered by existing super-resolution methods, and reveal multidimensional information of intracellular functional parameters, including chemical polarity, diffusivity, and reactivity, with nanoscale resolution and single-molecule sensitivity. By adding remarkably rich functional dimensions to the already powerful super-resolution microscopy, we thus open up new ways to reveal fascinating local heterogeneities in live cells.

Short Bio: Ke Xu is an assistant professor in Chemistry and a Chan-Zuckerberg Biohub Investigator at UC-Berkeley. Dr. Xu received his B.S. from Tsinghua University, did his Ph.D. work with Prof. Jim Heath at Caltech, and his postdoc work with Prof. Xiaowei Zhuang at Harvard University. Dr. Xu joined the Department of Chemistry at UC-Berkeley in the summer of 2013. His current research develops new physicochemical tools to interrogate biological, chemical, and materials systems at the nanoscale with extraordinary resolution, sensitivity, and functionality. To this end, his lab takes a multidimensional approach that integrates advanced microscopy, spectroscopy, cell biology, and nanotechnology. Dr. Xu is a Sloan Research Fellow, a Packard Fellow for Science and Engineering, a Beckman Young Investigator, and a Pew Biomedical Scholar, and has received an NSF CAREER Award, an NIH Director's New Innovator Award, and the Talented 12 by C&EN.
