Research

Our research program is largely experimental in nature and focuses on polymers and polymer-based composite materials, with particular emphasis on the fundamentals of transport of small molecules in polymers, which is applied in areas such as gas separation membranes, liquid separation membranes, water purification, and barrier packaging.
