Peter Doherty was born in 1940 in Brisbane. He attended veterinary school at the University of Queensland, and went on to complete his PhD at Edinburgh University. He took up a post-doctoral position with the John Curtin School of Medicine Research, where he researched how the body’s immune cells protect against viruses. He made a breakthrough in discovering the role of T cells in the immune system, for which, he received the Nobel Prize in Medicine in 1996, and was named Australian of the Year in 1997. Doherty currently splits his time between researching at St Jude Children’s Research Hospital in Tennessee and working in the Department of Microbiology and Immunology at the University of Melbourne.
