Dr. Fred Legrand Tsafack Tayong is a theoretical physicist specializing in nonlinear dynamics and complex systems, currently affiliated with the Fundamental Physics Laboratory, Department of Physics, Faculty of Science, University of Douala, Cameroon. He earned his PhD in Theoretical Physics from the University of Douala after completing his Master’s and Bachelor’s degrees in Physics at the same institution. His academic training is strongly grounded in mathematical modeling, analytical methods, and numerical simulations of nonlinear systems. Dr. Tsafack Tayong’s research focuses on nonlinear dynamics and chaos, van der Pol–type oscillators, stochastic dynamics, circadian rhythm modeling, and the application of nonlinear electronics concepts to biological systems. His doctoral research explored stochastic dynamics and entrainment phenomena in sleep–wake cycle models, contributing to a deeper understanding of biological oscillators under the influence of light and noise. He has published several peer-reviewed articles in reputable international journals, including Brazilian Journal of Physics, Nonlinear Dynamics, and Chaos, Solitons & Fractals, and actively collaborates with international researchers. Through his scientific contributions and conference presentations, he has gained academic recognition within the field of nonlinear physics. Dr. Tsafack Tayong continues to advance research at the interface of physics and biology, aiming to strengthen theoretical modeling approaches and foster scientific collaboration.
