About The Group
Our research combines organic-materials synthesis with nanofabrication and self-assembly to explore new chemistry, techniques, and phenomena in electro-active materials. Our main philosophy is sustainability through simplicity: we are bridging the gap between physics, engineering, and chemistry by developing simple tools that allow for systematic studies of new molecules on the bench-top.
There are three main tools in our arsenal: 1) the chemistry of organic materials, 2) nanoskiving, and 3) tunneling junctions comprising self-assembled monolayers. Currently we are focusing these tools on molecular electronics, photovoltaics, and conjugated polymers.


Molecular Electronics: We are developing new ways to contact ensembles of molecules on the micro scale, and collections of single molecules on the nanometer scale using EGaIn and Nanoskiving.
Photovoltaics: We are investigating new ideas for organic materials for the next generation of excitonic solar cells.
Conjugated Polymers: We are investigating new concepts in the synthesis and processing of conjugated polymers and the role of charges in their solubility.
