BACKGROUND

Dr. Balachandran received his B. Tech (Naval Architecture) from the Indian Institute of Technology, Madras, India, M.S. (Aerospace Engineering) from Virginia Tech, Blacksburg, VA and Ph.D. (Engineering Mechanics) from Virginia Tech. Currently, he is a Professor of Mechanical Engineering at the University of Maryland, where has been since 1993.

His research interests include nonlinear phenomena, dynamics and vibrations, system identification, and control. His recent efforts have focused on the following: i) taking advantage of nonlinear phenomena for the benefit of a system, ii) data-driven nonlinear dynamics, iii) interplay between noise and nonlinearity, iv) systems with delays, v) evolution of disease dynamics, and vi) space based solutions to address global warming. The publications that he has authored/co-authored include over hundred journal publications, a Wiley textbook entitled "Applied Nonlinear Dynamics: Analytical, Computational, and Experimental Methods" (1995, 2004), a Thomson/Cengage textbook entitled "Vibrations" (2004, 2009) and a third edition by Cambridge University Press (2019), and a co-edited Springer book entitled “Delay Differential Equations: Recent Advances and New Directions” (2009).
