Dr Rao is one of the few eminent Indian researchers, specialized in casting and solidification processing of light-weight alloys. Some of his earlier contributions include the development of technology for producing an Al-clad Mg-alloy strip through twin-roll casting, which inspired and attracted the attention of many other researchers. With his team at Brunel University, UK, he significantly contributed to the development of melt-conditioning in DC casting and successfully upscaled to SAPA aluminium (Sweden), now Norsk Hydro. As a part of this work, he worked with the University of Oxford, UK. He has authored around 70 articles in peer reviewed journals and conference proceedings with over 1350 citations and holds four patents. His research interests include solidification processing, un-diluted recycling of Aluminium; Artificial Intelligence, 3D-printing of metallic materials. Dr. Rao also serves as a reviewer for several research funding bodies of Malaysia, Czech Science Foundation, and Department of Science and Technology- India, and many reputed journals in his domain.

Dr. Prasadd earned substantial Industrial, Teaching and Research credentials during past 22 years, of which he spent a decade in overseas where he worked with:

Center for Advanced Aerospace Materials, POSTECH (www.postech.ac.kr ), Pohang, South Korea; College of North Atlantic-Qatar campus (https://www.cna-qatar.com/ ), Doha, Qatar; Brunel University (www.brunel.ac.uk ), London, UK; University of Oxford (www.ox.ac.uk) (Academic Visitor), UK; Universiti Malaysia Pahang (www.ump.edu.my)

Students who worked under the supervision of Prof. Rao in various research projects have published research articles in high quality SCI journals at their Undergraduate level and later embarked their further journeys to World's top Universities like University of Cambridge (U.K.); University Callifornia Berkeley (USA); National University of Singapore; Nanyang Technological University (Singapore) and so on...

Other Technologies Developed for Industry:

Integrated Melt-conditioned Direct-Chill casting technology of producing Al-alloys and Mg-alloys has been developed. Billets thus produced possess fine-equiaxed grain structure with minimized macro-segregation, in the absence of any grain-refiner additions; through dendrite-fragmentation. Which also enables significant scope of increase in the casting speeds.

 Worked at University of Oxford ( http://www.begbroke.ox.ac.uk/_) and successfully upscaled the above technology for industry scale.
