Our research group focuses on the development of mathematical modeling involving systems of differential equations and delay differential equations. Our research covers a wide range of topics, including population dynamics, the spread of infectious diseases, and human interactions in social systems. By constructing mathematical models, we analyze the dynamics of changes within populations and subpopulations based on the mechanisms that influence these systems. Our group welcomes interdisciplinary collaborations to enrich our approaches and foster innovative research that contributes to the understanding of dynamical systems.
