Biography

Born in Madras in 1978, Dr. Sundararajan Natarajan (Sundar) joined the Machine Design Section, Department of Mechanical Engineering, IIT Madras on 10th Sep 2014, as an Assistant Professor. Before this Sundar was a post-doctoral research fellow in the School of Civil & Environmental Engineering, The University of New South Wales, Sydney, Australia. Sundar graduated in Computational Mechanics with a PhD from Cardiff University, UK, under the guidance of Professor Stéphane PA Bordas and Dr Pierre Kerfriden.

Sundar is an active member of legato team. Sundar’s research interests includes development and application of advanced discretization techniques for moving boundary problems within a multi physics/multiscale framework.
