I received my Ph.D. in Physics in 2022 from the National Institute of Technology Sikkim, India. I am currently working as a Postdoctoral Fellow (Research Assistant) at the Lodz University of Technology, Poland. Previously, I held postdoctoral and research associate positions at the Indian Institute of Science Education and Research (IISER) Pune, India. My research interests broadly lie in the study of complex systems, with a focus on machine learning–based approaches for nonlinear dynamics and time-series analysis. I work on topics including extreme events, synchronization in networks, and data-driven modeling of dynamical systems. My research also includes applications in econophysics and interdisciplinary problems involving real-world data.
