Back to the basics to improve our ability to model infectious diseases

Abstract

Infectious disease modeling has become one of the hottest topics in mathematical biology but as I will show many of the models are suspect as certain basic mathematical techniques are overlooked. I will focus on models for HIV dynamics and show the ways that we can improve upon our modeling of diseases. For instance, numerous models have been used to predict parameters from patient data in HIV but applying a simple technique from algebra, called model identifiability, I have been able to show that the models we have been using are not identifiable to the parameters. Hence, we have begun to explore ways of putting modeling of ID on solid ground using techniques such as identifiability, sensitivity, and selection; also techniques from statistical methods such as bootstrapping and monte carlo.

I will comment on the progress that we have been making in these areas and also comment on improvements that we have found in modeling using delay differential equations.
