Guest:

Dr. Peter Doherty is Laureate Professor at the University of Melbourne. He and Dr. Rolf Zinkernagel, the co-recipient of the 1996 Nobel Prize in Physiology or Medicine, discovered how T cells recognize their target antigens in combination with major histocompatibility complex proteins. Beyond this, Dr. Doherty has made significant contributions to studying viral immunity, with a strong focus on how the immune system responds to influenza and other respiratory viruses.

In this episode, he talks about beginning his career as a veterinarian studying sheep and his seminal discoveries on the mechanisms of T cell antigen recognition. He also discusses his ventures into science communication. (38:08 )
