About Me: Dr. Suman Saha is an Assistant Professor of the Mechanical Engineering department of Indian Institute of Technology (Indian School of Mines) Dhanbad. Back in December 2022, he defended his PhD thesis working in the broad area of sustainable minimum quantity lubrication in high-speed micro-milling at IIT Kharagpur. His PhD research works got published in eight core manufacturing and tribological journals including JMPT, IJMS, JMP, and Wear. Soon after completion of PhD, he joined IIT Bombay to pursue post-doctoral research on micro-machining of magnesium alloy. He was there for a few months before joining IIT (ISM) Dhanbad as a faculty in October 2023. Here he is working on the broad area of subtractive manufacturing, surface integrity control, stress management, ferrofluidic tribology, and industrial sustainability. Parallelly, he is teaching courses at both the undergraduate and postgraduate levels, advising students and scholars, participating in the intellectual activities of the Department and Institute, and providing services to the Institute. He loves to travel and explore new places and engage in intellectual pursuits.

Research Interest: Machining; Deburring; Cutting fluid; Residual stress management; Ferrofluidic tribology; Industrial sustainability
