About myself


@LAMP 2019 conference, Hiroshima, Japan

Hello, I am Sagar Sarkar. Presently, I am an Assistant Professor in Mechanical Engineering Department, IIT Delhi. I completed my B.Tech (Honours), M.tech and PhD- all from Indian Institute of Technology, Kharagpur. I continued two more years as a Senior Scientific Officer in the same institute where I was involved in developing a system for metal additive manufacturing with facility for real-time process monitoring and its control. The system was indigenously built and is first of its kind. Together with the team, I was also actively involved in other important indigenous developments such as laser assisted cold spray, laser shock deposition etc. I am working broadly in the area of Laser Material Processing for more than 10 years . My research interests include understanding the mechanical properties of additively manufactured parts under dynamic loading conditions mainly fatigue and online process monitoring in laser based additive manufacturing processes to ensure repeatable and reproducible part properties. Also, I am actively involved in other laser material processing applications and open to collaborative research works to develop better understanding of the process.

I strongly encourage undergraduate students to explore the possibilities of taking research as their career. You will be surprised to know what a laser can do and the exciting opportunities ahead in the coming years in the area of Additive Manufacturing/3D printing!!! It is not only about the academic research, but can be a startup too. We need people to join our hands.

I follow an open door policy. You are welcome to discuss your ideas and together we can make it happen.
