Calistus Ngonghala, Ph.D.
General Research Interests
Mathematical epidemiology and ecology, mathematical modeling, applied mathematics, differential equations, nonlinear dynamics, and dynamical systems
• Mathematical modeling of epidemiological/biological processes (applying deterministic, stochastic, network, and agent-based modeling techniques to investigate the epidemiology, population dynamics, immunology, and control of infectious diseases. Model calibration, sensitivity analysis and applying optimal control theory to evaluate optimal disease control and surveillance measures).
• Mathematical modeling of feedbacks between infectious diseases, economic growth and land-use change (applying mathematical, statistical and computational techniques to model the interplay among infectious diseases, economic development and land-use change and to determine optimal economic growth and health intervention measures).
• Dynamical systems (applying the theory of dynamical systems, applied nonlinear analysis, and numerical methods to study extreme multistability involving the co-existence of an infinite number of attractors in coupled biological, chemical and physical systems).
Dr. Ngonghala is currently working with Dr. Matthew Bonds, an economist in the Department of Global Health and Social Medicine, on a project to develop mathematical models of effects of health care on cycles of poverty and disease.
