Overview
I am a postdoctoral researcher in the department of Physics and Astronomy at the University of Exeter, England, United Kingdom, working in a project funded by the Royal Society TATA University Research fellowship. I earned Ph.D. in mechanical engineering from Indian Institute of Technology (IIT) Kanpur, India in February 2022. My research interest and expertise lie in solid mechanics and design stream of mechanical engineering. My thrust area of research is Elastic wave physics, Mechanical metamaterials, Dynamics, Vibrations, Piezoelectric-based energy harvesting, and Vibration control.

My professional qualifications have been acquired in India. I obtained a bachelor's degree in mechanical engineering from Noida Institute of Engineering and Technology, Greater Noida, affiliated with Dr. A.P.J. Abdul Kalam Technical University, Lucknow, Uttar Pradesh, India. Later, I qualified for GATE (Graduate Aptitude Test in Engineering, GATE 2015 score- 706/1000) for postgraduate study fellowships in India. I was awarded a junior research fellowship from the National Institute of Technology (NIT) Jamshedpur, Jharkhand, India, for completing my master’s degree in mechanical engineering. After that, I inclined more towards research and moved to the mechanical engineering department, Indian Institute of Technology (IIT), Kanpur for doing Ph.D.
I was a recipient of the Visvesvaraya Fellowship under the Visvesvaraya Ph.D. Scheme, Ministry of Electronics and Information Technology, Government of India, for pursuing my doctoral study (2016-2021) at IIT Kanpur. During my Ph.D. in 2018, I got the Sakura science research fellowship under the Japan-Asia Youth exchange program in science. I visited IPS Waseda University, Kitakyushu, Japan, for a project based on pipe health monitoring. I was also a SPARC research fellow (2019-2021) under the Scheme for Promotion of Academic and Research Collaboration (SPARC), Ministry of Education, Government of India. I visited Swansea University, Wales, United Kingdom, to carry out joint research and share knowledge under the SPARC project on Energy harvesting using Piezo embedded Mechanical metamaterials. In my Ph.D. thesis, I investigated the piezo-embedded mechanical metamaterials, namely negative stiffness and negative mass metamaterials, for energy harvesting and vibration control. The propagation characteristics exhibited by discrete locally resonant lattice structures based on negative stiffness and mass properties are further implemented to continuous systems like beams. Euler-Bernoulli beam-based metamaterial with periodically attached double negative local resonators is analyzed to understand the locally resonant bandgaps. Subsequently, experiments are performed to comprehend the bandgap formation and energy harvesting possibilities on the designed and manufactured metastructure based on the beam.
After completing my PhD from IIT Kanpur, I joined as postdoctoral research associate in the department of Physics and Astronomy, University of Exeter, England, United Kingdom. My postdoctoral project aims to do research on confining elastic wave energy to one dimension.
