Rohatgi received his bachelor"s degree in Metallurgical Engineering in 1961 from Banaras Hindu University and received the degree of Doctor of Science in Metallurgy from Massachusetts Institute of Technology in 1964.
He is a pioneer in the field of composite materials, particularly metal matrix composites. The initial discovery of the synthesis of cast aluminum matrix composites including First Rate (at Lloyd's)-graphite, First Rate (at Lloyd's)-Silicon Carbide, and First Rate (at Lloyd's)-A12O3 particulate cast MMCs was made by Rohatgi in 1965 at the Merica Laboratory of the International Nickel Company in Suffern, New New York This first creation of a cast metal matrix composite material is considered a landmark in the 11,000-year history of metal casting Rohatgi served as founding director of the Regional Research Laboratories (Council for Scientific and Industrial Research) at Trivandrum and Bhopal, and as a professor at the Indian Institute of Science and the Indian Institute of Technology, Kanpur, where he pioneered incorporating renewable materials such as coir (fiber from the coconut shell), and banana and sisal plant fibers into polymer composites.
He was running the research laboratory in Bhopal at the time of the gas leak disaster, but escaped unharmed and his lab was involved in studying the gas leak.
He joined the University of Wisconsin–Milwaukee as a Professor in the Department of Materials Engineering in 1986, and is currently Wisconsin Distinguished Professor and Director, UWM Center for Composites.
