Teaching & Research Interests: 

My research interests are in the following broad areas. Vibrations and Nonlinear Dynamics, Aeroelasticity and Energy Harvesting from Vibrating Structures. Recently, I have started working on human voice production from the purview of non-smooth nonlinear dynamical systems. Those interested in the above areas are encouraged to contact me for further details.
