Welcome to my website. :-)
I am a researcher working at the intersection of nonlinear dynamics, complex networks, and eco-evolutionary systems. My work focuses on understanding how coherent and emergent collective behaviors arise in coupled oscillators and complex networks under competitive, attractive, and repulsive, and time-varying interactions. By combining analytical techniques, numerical simulations, and network-theoretic approaches, I investigate how topology, temporal structure, and interaction asymmetry shape macroscopic dynamical outcomes.
I currently serve as a Guest Scientist at Constructor University (formerly Jacobs University), where I previously held a Research Associate (Postdoctoral Fellow) position from April 2024 to April 2026. Before that, I was a postdoctoral scholar in the Department of Environmental Science and Policy at the University of California, Davis, where my research advanced into ecological synchronization and resource-mediated dynamical systems.
I obtained my Ph.D. from the University of Calcutta (Research conducted at the Physics and Applied Mathematics Unit in the Indian Statistical Institute, Kolkata), where my research centered on collective dynamics in static and time-varying networks. More recently, my interests have broadened to eco-evolutionary dynamics and evolutionary game-theoretic models, including paradigmatic social dilemmas such as the Prisoner's Dilemma and Snowdrift games, as frameworks for understanding cooperation and resilience in ecological systems.
I will be available for new research opportunities starting May 2026. I am particularly interested in positions that advance fundamental questions in complex systems, time-varying networks, and interdisciplinary applications of nonlinear science.
