Wei-Shun Chang is an Assistant Professor in the Department of Chemistry and Biochemistry at UMass Dartmouth. He obtained B.S. and M.S. in Chemistry from National Taiwan University in 1996 and 1998, respective. After working in the semiconductor industry for a few years, he studied the electro-optical properties of conjugated polymer supervised by Prof. Paul Barbara in the University of Texas at Austin and received Ph. D. in Physical Chemistry in 2007. He joined Link group at Rice University in 2007 as a postdoctoral researcher and promoted to a research fellow since 2012. He joined UMass Dartmouth in 2018. His research interest is to study optical properties of plasmonic nanomaterials at single particle level for the applications of renewable energy, optical sensing, and medical treatment. He has developed steady-state and time-resolved spectroscopic techniques to investigate collective optical properties of plasmonic nanoparticles, plasmon-mediated chemistry, chiral plasmonics, and plasmon optomechanics. In the MUST program, he will develop high-sensitivity fluorescence imaging technique to probe the bacterial population in biofilm and explore novel nanomaterials to suppress the growth of biofilm.
