His work focuses on the demography of health, particularly the epidemiology of infectious diseases, and the length of life. Noymer's work looks at infectious diseases as a product of social and biological interaction, focusing on disease at the population level, but grounded in the underlying biology of the relevant pathogens. Among other topics, he has published on life expectancy, and on the epidemiology of measles, influenza, tuberculosis, Ebola, and Clostridium difficile. Prof Noymer received his PhD in sociology from UC Berkeley, his MSc in medical demography from the London School of Hygiene &amp; Tropical Medicine, and his AB in biology from Harvard.
