William Mair completed his BSc in Genetics and PhD in Biology at University College London, UK. He moved to San Diego to carry out his postdoctoral training at The Salk Institute for Biological Studies in La Jolla, before joining Harvard as an Assistant Professor in November 2011. The Mair lab’s research studies the basic biology of the aging process, driven by the central question: Why are we more likely to get chronic diseases when we are old than when we are young? What goes wrong in cells and tissues to increase overall disease risk, and is this decline inevitable, or can we reverse it to bring healthy years to the elderly?
