Gregory C. Rutledge is the Lammot du Pont Professor of Chemical Engineering at the Massachusetts Institute of Technology (MIT) and the Lead PI for MIT in AFFOA, a Manufacturing Innovation Institute focused on functional fabrics. He served as Director of the Program in Polymer Science and Technology and as Executive Officer in the Department of Chemical Engineering at MIT. He is a Fellow of the American Institute of Chemical Engineers, the American Physical Society, and the Polymer Materials Science and Engineering (PMSE) Division of the American Chemical Society, and he is a recipient of The Founders Award of the Fiber Society. He was the H.A. Morton Distinguished Visiting Professor in Polymer Science at the University of Akron, and a Thinker in Residence at Deakin University in Geelong, Australia. Prof. Rutledge’s research on molecular engineering of soft matter examines relationships between processing, structure and properties of engineered polymers, using statistical mechanics and knowledge of their molecular structure. His expertise includes both computations and experiments. His group has been instrumental in the development of molecular level modeling of polymer crystals, crystallization kinetics, and the structure and properties of semicrystalline materials. Since 2001 he and his coworkers have published extensively on the fabrication, properties and applications of ultrafine polymer fibers formed by electrospinning. Prof. Rutledge is an editor for the Journal of Materials Science and serves on several editorial boards.
