Dr. Praveen Sathiyamoorthi joined the Department of Metallurgical Engineering at IIT (BHU) Varanasi as an Assistant Professor in March 2022. His research interests focus on the deformation behavior of metallic materials and the development and characterization of high-performance alloys for extreme environments. Currently, his research group is working on developing concentrated alloys using a multi-principal element design approach to achieve properties that surpass those of conventional materials. He leads a research portfolio with over ₹2.0 Crore in funded projects from organizations such as DRDO, ANRF, and Tata Steel.

Dr. Sathiyamoorthi completed his Bachelor of Engineering in Metallurgical Engineering at the Government College of Engineering, Salem, in 2009. He began his research career with an eight-week undergraduate summer internship in the Department of Mechanical Engineering at IISc Bangalore in 2008. He then pursued a dual degree (MS & PhD) in Metallurgical and Materials Engineering at IIT Madras, completing it in 2016. Afterward, he was awarded the prestigious Korea Research Fellowship (KRF, now known as the Brain Pool Fellowship) for postdoctoral research at Pohang University of Science and Technology (POSTECH) in South Korea, where he worked from 2017 to 2022. Additionally, he received the POSTECH Initiative for Fostering the Unicorn of Research and Innovation (PIURI) Fellowship from 2020 to 2022.
