Biography

Thalappil Pradeep is an Institute Chair Professor at the Indian Institute of Technology Madras (IITM), Chennai, India. He is the Deepak Parekh Institute Chair Professor and is also a Professor of Chemistry. He studied at the University of Calicut, Indian Institute of Science (IISc), UC Berkeley, and Purdue. His research interests are in molecular and nanoscale materials, Ice Chemistry, Microdroplets Chemistry, Atomically precise nanoclusters. He is an author of over 615 scientific papers in journals and is an inventor of over 100 issued patents. He is involved in the development of affordable technologies for drinking water purification and some of them have been commercialized. His pesticide removal technology has reached about 10 million people. His arsenic removal technology, approved for national implementation, is delivering arsenic free water to about 1.4 million people every day at a cost of 2.5 paisa/L. Along with his associates, he has incubated seven companies and three of them have production units. He is the author of the introductory textbook, Nano: The Essentials (McGraw-Hill) and is an author of the monograph, Nanofluids (Wiley-Interscience) and an advanced textbook, A Textbook of Nanoscience and Nanotechnology (McGraw-Hill). He is on the editorial boards of journals such as ACS Nano, Chemistry of Materials, Analytical Chemistry, Chemical Communications, Nanoscale, JPC Letters, etc., and is an associate editor of ACS Sustainable Chemistry & Engineering for ten years. He is now an Associate Editor of ACS Sustainable Resource Management. He has authored popular science books in English and Malayalam and is a recipient of Kerala Sahitya Akademi Award for knowledge literature. He has received the prestigious Padma Shri, Vigyan Shri, Lifetime Achievement Research Award of IITM and Distinguished Alumnus Award of IISc. As part of philanthropy, he supports a school in his village where 500 students are on rolls.
