About Me

Animated illustration of a wave losing amplitude as it passes through a chain of masses with local resonators — Try the interactive version: choose a frequency and watch the chain respond.

I study how elastic waves travel through engineered structures, and how to design metamaterials that stop unwanted vibration.

I am an ANRF National Postdoctoral Fellow in the Department of Aerospace Engineering at the Indian Institute of Science (IISc), Bengaluru, working with Prof. Rajesh Chaunsali on wave propagation and low-frequency vibration isolation in sandwich structures for aerospace applications.

I received my Ph.D. in Civil Engineering (Structural Engineering) from IIT Delhi under Prof. Arnab Banerjee, with a Distinction in Doctoral Research. My work combines analytical theory, numerical simulation and laboratory measurement, using multiple-scales perturbation methods, Bloch–Floquet analysis, finite-element modelling and laser Doppler vibrometry.

Research themes

Bandgap theory

Closed-form results for attenuation peaks and band boundaries in metamaterials.

Vibration isolation

Rigid-elastic metabeams, relative resonance and low-frequency isolation.

Nonlinear waves
