The earliest gains in life expectancy were made by understanding infectious diseases, first through epidemiology and then through microbiology.
So what processes govern the spread of infections in populations? Why do some pathogens come and go while others are very persistent?
Why are we now facing new threats from BSE, SARS and bird flu, and how worried should we be?- Gresham College
Professor Christopher Dye is based at the World Health Organization, where he evaluates epidemiological and economic trends for tuberculosis, malaria, and other infectious diseases, measures the impact of control programs, and presents the findings to governments, scientists, and the media.
Professor Dye holds a BA from the University of York and a DPhil from the University of Oxford and has taught at Cambridge University, Imperial College and the London School of Hygiene and Tropical Medicine. He was elected a fellow of the Academy of Medical Sciences in 2008.
His work in epidemiology is described in more than 200 scientific papers, and he is currently a member of the editorial board of science.
Christopher Dye discusses emerging infectious diseases that could form the "coming plagues" and describes the scientific research that tries to identify diseases that pose the biggest threat to human populations.
