Precision Ag Sensing Systems

Welcome to Organic Electronics Laboratory!


We are an active group of graduate students, postdocs, and research fellows, investigating various aspects of organic electronics including OPVs, OLEDs and OFETs.

If you want to learn about what we have done recently or what we are working on, please visit our research and publications pages. If you are interested in joining in our group as a research assistant or a postdoctoral researcher, send me an email at
