Dr. Harris specializes in scalable, roll-to-roll (R2R) manufacture of polymer/thin-film coatings for use in flexible electronics, alternative energy devices, batteries, pharmaceuticals, food and water, and other applications.

Seeking to improve the quality and scalability of polymer thin films, Dr. Harris's research program focuses on (1) understanding the behavior of fluids as they are coated onto permeable or impermeable substrates to elucidate the mechanisms that govern process-structure-property relationships and (2) the design and implementation of innovative coating technologies to create discrete patterns and multiple layers as well as to coat with multiple fluids simultaneously. 

Her work can be applied to electrochemical devices, such as fuel cells, electrochemical capacitors, electrolysis cells, batteries, and electrodialysis process as well as flexible electronic devices and water filtration systems among others. 

The challenges when transitioning lab-scale thin-film coatings to commercial-scale include coating uniformity, controlling wide-area film formation, wetting and rheological issues, and tooling limitations. To ensure material performance does not suffer during scale-up, Dr. Harris's research program is a synergistic blend of modeling, application technology, scholarly perspective (reviews), and signature breakthroughs in technology development.
