DESCRIPTION :

Deepak Nayak has been working as a scientist at the CSIR-Institute of Minerals and Materials Technology, Bhubaneswar, since 2015. Born in 1989 in Bhubaneswar, he graduated from the NIT, Rourkela, with a B.Tech in Metallurgical and Materials Engineering before working at JSL Stainless Ltd., New Delhi, in 2010. After his 1-year career as a graduate engineer trainee there, he returned to Bhubaneswar, where he received his M.Tech from Academy of Scientific & Innovative Research (CSIR-IMMT) in 2013. He has been involved in managing projects from concept to commercialization in the areas of ferrous metallurgy, including mineral beneficiation of low-grade iron ores, microwave processing, and extraction of valuable metals.
