Margaret Sobkowicz-Kline

Research and teaching in the Sobkowicz-Kline Group is at the convergence of materials and engineering for environmental sustainability. We are interested in the role that polymeric materials can play in creative solutions to the critical challenges our society faces on this planet.

We have ongoing projects studying structure-property relationships and novel synthesis techniques for bio-based and biodegradable polymers. We focus on processing strategies for improving properties and expanding applications of these bioplastics.

We are also interested in electroactive polymers for new energy applications, such as organic photovoltaics and efficient thermal management. Our current research is focused on development of new green manufacturing techniques of these novel energy materials.
