Jianjun Wei

Biosketch: Dr. Jianjun Wei joined the University of North Carolina at Greensboro in 2013, and is an Associate Professor of Nanoscience leading a research group at the Joint school of Nanoscience and Nanoengineering (JSNN). Prior to joining JSNN, he had worked in CFD Research Corporation in Huntsville, AL, from 2006 to 2013, and led as a Principal Scientist (PI and co-PI) for a number of BAA, SBIR/STTR Phase I, II, and III US government contracts, primarily through NIH, NASA and DOD research grants. He obtained his Ph.D. in chemistry in 2004 at the University of Pittsburgh, followed with one-year postdoctoral fellowship at the same university. Dr. Wei was a lecture and researcher at Shanghai University during 1995-2000, and graduated with degrees of M.E. in 1995 and BS in 1992 in Applied Chemistry from East China University of Science and Technology, Shanghai, China. Research Interests: Dr. Wei’s research is well centered in the cutting-edge nanoscience and nanotechnology areas, with a particular emphasis on a few important fundamental aspects of nanoscale systems under electrical, optical and/or magnetic fields, as well as its applications in biosensors for diagnosis, nanomedicine, and catalysis for energy conversion and storage. More specifically, he investigates both fundamentals of structure-correlated electron/energy transfer and nanoscale plasmonics with a motivating philosophy of exploiting synergies between functionalities and nanoscale materials or structures. His research is highly interdisciplinary and employs broad methods of materials synthesis, nanofabrication, self-assembly, electrochemistry, microscopy, spectroscopy, and computational modeling and simulation. The diagram illustrates the overview of his research theme and current focuses.
