Research Description

My research is focused on the understanding of intermolecular effects in ordered media. In particular we are investigating the effect different media impart upon chemical reactivity with the goal of designing organic systems with specific functional control. This broad research goal encompasses a number of different fields including semiconducting polymers for molecular electronics, biodegradable polymers for drug delivery and the synthesis of carbon nanotubes of one type through topochemical reactions.  For a more detailed description of research projects go to the group webpage at
