Large-scale, nonlinear dynamic models frequently arise when describing the physics of important engineering and biological problems. In this research, we are developing new algorithms that exploit concurrent computing architectures to provide efficient parallel solution of large-scale parameter estimation problems, focusing on those with both temporal and spatial structure that can be exploited.

Parameter estimation for infectious diseases plays an important role in the understanding of disease dynamics and decision-making in public health policies. This research focuses on developing advanced modeling techniques and solution strategies for disease-related parameter estimation problems resulting in mixed-integer nonlinear programming problems (MINLPs).

Infectious diseases have plagued communities all over the world throughout history, and they continue to kill countless numbers of people every year. Developing dependable models for the spread of infectious diseases can help provide an understanding of such spread and allow evaluation of public health policies. The goal of this research is to use dynamic optimization for parameter estimation of spatio-temporal models of the spread of measles.
