I am a theoretical quantum physicist specializing in quantum optics, quantum information theory, and nonlinear dynamics. I earned my Ph.D. in Physics from the University of Mysore, Mysuru, in 2021.

From 2021 to 2023, I was a postdoctoral fellow at the Indian Institute of Science Education and Research (IISER), Mohali, working in the Quantum Optics and Quantum Information Group. My research there focused on foundational and applied aspects of quantum mechanics, including geometric phases, spin squeezing, and entanglement.

Between 2023 and 2025, I held a postdoctoral position at the Hebrew University of Jerusalem, Israel, in the Nonlinear Physics Group, where I studied soliton interactions and related nonlinear wave phenomena. I also spent three months as a postdoctoral fellow at the Jawaharlal Nehru Centre for Advanced Scientific Research (JNCASR), Bengaluru, in the Engineering Mechanics Unit, applying mathematical physics methods to problems in continuum mechanics.

My work combines analytical techniques and mathematical modeling to investigate complex quantum and nonlinear systems. I have contributed to understanding how geometric phase manifest in quantum systems, the generation and characterization of quantum correlations, and the dynamics of nonlinear excitations in diverse physical settings.

Broadly, my research interests include mathematical physics, quantum optics, quantum information theory, nonlinear dynamics, and continuum mechanics.
