Kailong Jin

Asst Professor
Faculty, TEMPE Campus, Mailcode 6106

Kailong Jin is currently an assistant professor in chemical engineering in the School for Engineering of Matter, Transport and Energy (SEMTE) at Arizona State University, where he began in 2020.  Kailong Jin earned his Ph.D. in chemical engineering with a Distinguished Graduate Researcher Award from Northwestern University under the direction of Professor John Torkelson. Then, he worked as a postdoctoral researcher with Professors Frank Bates and Christopher Ellison in the Department of Chemical Engineering and Materials Science at the University of Minnesota. His research broadly seeks to design, synthesize, engineer, and characterize polymeric materials that can help address technological issues in energy, the environment, and sustainability.
