About Me: Dr. Ranjit Kumar Upadhyay is a Professor (HAG) in the Department of Mathematics & Computing, Indian Institute of Technology (Indian School of Mines), Dhanbad, India. He is an acknowledged researcher and has contributed in various areas of Applied Mathematics, Mathematical modeling and Nonlinear Dynamics. His research areas are interdisciplinary in nature like dynamical systems theory; chaotic dynamics of real-world situations; population dynamics; spatial dynamics and pattern formations in biological populations, e-epidemic and neural models; and reaction-diffusion modeling. He has published 220 research papers in different International Journals of repute and a number of these publications are with international collaborators. He has supervised 15 students for their Ph.D. Currently, 6 students are working under his guidance for their Ph.D. degree. He has handled a number of sponsored R&D projects. He is the co-author of the text Book titled “Introduction to Mathematical Modeling and Chaotic Dynamics” & “Spatial dynamics and Pattern formations in biological populations” published by Taylor & Francis group (CRC Press, USA). He is an Editor-in Chief of the Journal of Innovation Science & Sustainable Technologies and subject editor of for National Academy Science Letters and on the Editorial Board for many reputed Journals. He is an Associate Editor of the Elsevier Journal “Food Webs” and Springer Journal “Advances in Difference Equations” and “Differential Equations and Dynamical Systems”. He is a Guest Editor of a Special Issue entitled “Nonlinear Models in Biosignaling, Biosensor and Neural Systems – Modeling, Simulations, and Applications” being brought out by the Springer Journals “Differential Equations and Dynamical Systems”. He was a visiting research fellow under the Indo-Hungarian Educational exchange program in Eötvös University, Budapest, Hungary. He was a visiting scientist and delivered invited lectures in many renowned institutions like University of Cambridge; University of Leicester, UK; University of Le Havre Normandie, France. He is a member of the International Society of Computational Ecology, Hong Kong.
Research Interest: Nonlinear Differential Equations (ODE, PDE, Delay, Cross-diffusive), Chaos Modeling, Mathematical Ecology, Nonlinear dynamics, Dynamical system Theory, Disease dynamics, Population dynamics, Reaction-Diffusion Modeling, Spatiotemporal pattern formations, Virus dynamics, Brain dynamics and Neural modeling.
