My research is focused towards understanding and exploiting the dynamics of physical and engineering systems with nonlinear effects. Traditional design practices neglected the influence of nonlinearity due to the non-existence of a generalized computational frame-work and the difficulty in understanding the complex dynamics. With the advancement in computational power, efficient algorithms and experiments, there is a paradigm shift in the conventional thought process and lead to a new research direction “`Exploitingthe nonlinear behavior in physical systems to improve its performance”‘. My research is in line with the above thought process and it was understood that careful inclusion of nonlinearities in physical systems can improve the performance of the systems compared to the linear counterpart. This is demonstrated through real world applications such as bistable systems for energy harvesting, negative stiffness vibration isolation mechanism and multi-functional energy harvesting models.I am part of the thrust area group “Computational Nonlinear Dynamics and Vibrations” at Amrita Vishwa Vidyapeetham.
