Dr. Sixuan Li is a postdoctoral research associate in the BioMEMS and Single Molecule Dynamics laboratory at Johns Hopkins University. He obtained his PhD in the same lab under advised by Dr. Jeff (Tza-Huei) Wang. His research focuses on developing and applying innovative methods in single-molecule analysis including nucleic acids, proteins, and nanoparticles to help understand the fundamental questions of drug delivery. His multidisciplinary approach draws from biophysics, chemistry, optics, and engineering to push the boundaries of scientific knowledge. He has published 10 peer reviewed research articles, and he holds one patent on the characterization of nanoparticles. Dr. Li is currently commercializing the nanoparticles analysis platform, and has been working on the CICS Analytics, a startup company that leverages single molecule fluorescence spectroscopy and cutting-edge toolkits to provide comprehensive analysis of therapeutic nanoparticles for cell and gene therapy applications.
