Hatred is one of the most destructive human emotions, responsible for some of the greatest atrocities that humans have committed against each other. But why did it evolve in the first place? What is the evolutionary advantage of hating someone? Why is hate the ‘evil twin’ of love? And will we ever be able to ‘treat’ hatred and open the door to a utopian world of peaceful coexistence?

This lecture was recorded by Robin May on the 4th of March 2026 at Bernard’s Inn Hall, London

Professor of Infectious Disease at the University of Birmingham, and (interim) Chief Scientist at the UK Health Security Agency, Robin May was appointed Gresham Professor of Physic in May 2022. Between July 2020 and September 2025 he served as Chief Scientific Adviser at the Food Standards Agency (FSA).

Professor May’s early training was in Plant Sciences at the University of Oxford, followed by a PhD on mammalian cell biology at University College London and the University of Birmingham. After postdoctoral research on gene silencing at the Hubrecht Laboratory, The Netherlands, he returned to the UK in 2005 to establish a research program on human infectious diseases. He was Director of the Institute of Microbiology and Infection at the University of Birmingham from 2017-2020. 

Professor May continues his work on Infectious Disease at the University of Birmingham. A Fellow of the Academy of Medical Sciences, Wolfson Royal Society Research Merit Fellow and Fellow of the American Academy of Microbiology, Professor May specialises in research into human infectious diseases, with a particular focus on how pathogens survive and replicate within host organisms.

As the FSA’s Chief Scientific Adviser, Professor May provides expert scientific advice to the UK government and plays a critical role in helping to understand how scientific developments will shape the work of the FSA, as well as the strategic implications of any possible changes.
