Dr. Gamini Mendis specializes in polymer sustainability, with active research projects on life cycle analysis of plastics, plastics in food packaging, the end-of-life fate of plastics in the environment, and post-consumer recycling and upcycling. He is also investigating the implementation of smart manufacturing technologies to improve efficiency and reduce material waste.

Dr. Mendis received his Ph.D. and B.S. in Materials Science and Engineering from Purdue University. During his Ph.D., he held a fellowship through a National Science Foundation – IGERT program focused on sustainable electronics. He also held two post-doctoral research appointments, examining smart and sustainable manufacturing technologies with John Sutherland in Environmental and Ecological Engineering at Purdue University and the second studying waste to materials and energy systems with Alicyn Rhoades in Plastics Engineering Technology at Penn State Behrend.
