Research interests

Our research is centered on organic-materials chemistry: the design, synthesis and implementation of organic (macro)molecules that mitigate the generation and flow of electricity in thin-films and interfaces.

  • Molecular Electronics
  • Self-assembled Monolayers
  • Conjugated Polymers
  • Unconventional Nanofabrication
  • Organic Photovoltaics and Thermoelectrics
