We are always seeking creative and dedicated engineers and scientists!  More information here.

The Winey Lab at the University of Pennsylvania employs a variety of experimental and computational tools to probe the structural and physical properties of advanced polymers.  We are studying and designing functional polymers to improve ion and proton conductivity targeting a variety of energy applications.  In polymer nanocomposites our current interests focus on nanoparticle dynamics across a range of time and length scales.  Our newest project focuses on polymer-to-polymer upcycling to convert waste polyolefins to higher value polymers.
