Gautam Menon (IMSc): Contagion: Modelling Infectious Diseases Monday 29th June 345--500pm Chair: Krishna Maddaly Mathematical models play a crucial role in understanding how infectious diseases, such as Ebola, flu, measles, tuberculosis and AIDS, spread within a population. They also help decide the strategies that public health officials and governments must use in response to outbreaks. I will motivate the general study of models of infectious diseases from a historical perspective, describe some of these models very simply and then explain how they have been used and continue to be used in real-life situations. Studies of such models lie at the interface of applied mathematics, data science, bio-statistics and public policy, providing an interesting example of how, in some cases, improved mathematical methods can really make the difference between life and death.
