Karen I. Winey serves as the Harold Pender Professor in the Department of Chemical and Biomolecular Engineering and Materials Science and Engineering at the University of Pennsylvania's School of Engineering and Applied Science. Her research group employs experimental and computational tools to investigate advanced polymers for energy applications, particularly focusing on proton and ion conductivity for fuel cells and batteries within the Laboratory for Research on the Structure of Matter (LRSM).
Dr. Winey's research encompasses:
- Designing functional polymers to improve proton, hydroxide, and ion conductivity
- Studying polymer nanocomposites and nanoparticle dynamics in electrochemical devices
- Developing polymer-to-polymer upcycling methods to convert waste polyolefins to higher value polymers
- Revolutionizing understanding of ionomer morphologies beyond traditional spherical aggregate models
Her recent publications reveal significant advances in sustainable energy materials, particularly fluorine-free alternatives to conventional polymer electrolytes. The research spans fundamental studies of ion transport mechanisms in precisely engineered polymers to practical applications in energy devices. A critical focus is understanding how nanoscale morphology affects macroscopic properties, with particular attention to structure-property relationships in ion-conducting polymers for fuel cells and batteries.
Scientific recognition includes:
- 2025 Turner J. Alfrey Visiting Professor
- Harold Pender Professorship (endowed chair)
- NSF DMR Polymers grant awarded July 2025
Dr. Winey actively mentors a diverse research group including PhD students, postdoctoral researchers, and undergraduates. Her lab recently welcomed six summer undergraduates and has celebrated numerous student achievements including qualifying exam successes and award-winning presentations. Current major projects include the Port5 collaboration and the PolyUp project focused on polymer upcycling through dehydrogenation and functionalization strategies.
The Winey Group operates within Penn's state-of-the-art Vagelos Laboratory for Energy Science and Technology (VLEST), maintaining active collaborations with institutions including the University of Konstanz in Germany, Florida State University, and Michigan State University. The group regularly hosts international visitors and participates in major conferences including the APS Global Physics Summit.
