Sabu Thomas, PhD, is a professor of polymer science and engineering at the School of Chemical Sciences and director of the Centre for Nanoscience and Nanotechnology at Mahatma Gandhi University, Kottayam, Kerala, India. He received his BSc (1980) in chemistry from the University of Kerala, Tech. (1983) in polymer science and rubber technology from the Cochin University of Science and Technology, and PhD (1987) in polymer engineering from the Indian Institute of Technology, Kharagpur. The research activities of Professor Thomas include surfaces and interfaces in multiphase polymer blend and composite systems; phase separation in polymer blends; compatibilization of immiscible polymer blends; thermoplastic elastomers; phase transitions in polymers; nanostructured polymer blends; macro-, micro- and nanocomposites; polymer rheology; recycling; reactive extrusion; processing-morphology-property relationships in multiphase polymer systems; double networking of elastomers; natural fibers and green composites; rubber vulcanization; interpenetrating polymer networks; diffusion and transport; and polymer scaffolds for tissue engineering. He has supervised 64 PhD theses, 30 MPhi. theses, and 40 masters theses. He has three patents to his credit. He also received the coveted Sukumar Maithy Award for the best polymer researcher in the country for the year 2008. Very recently Professor Thomas received the MRSI and CRSI medals for his excellent work. With over 600 publications to his credit and over 15,000 citations, with an h-index of 65, Dr. Thomas has been ranked fifth in India as one of the most productive scientists.
