Robert May

Robert May. Robert McCredie May, Baron May of Oxford, was an Australian-born scientist who made profound contributions to theoretical ecology and complex systems, fundamentally reshaping the understanding of stability in natural ecosystems. His work bridged mathematical biology and public policy, leading to influential roles as Chief Scientific Adviser to the UK Government and President of the Royal Society. He was renowned for applying rigorous mathematical models to urgent global issues like biodiversity loss and infectious disease outbreaks.

Early life and education

Born in Sydney, he displayed an early aptitude for physics and mathematics. He attended Sydney Boys High School before enrolling at the University of Sydney, where he initially studied chemical engineering. He completed a Bachelor of Science in theoretical physics in 1956, followed by a Doctor of Philosophy in theoretical physics from the same institution in 1959. His doctoral research, supervised by Harry Messel, focused on quantum many-body problems, a foundation that later informed his analytical approach to biological systems.

Academic career and research

May began his academic career in physics at the University of Sydney before moving to Harvard University as a postdoctoral researcher. A pivotal shift to biology occurred during his tenure at Princeton University, where he became a professor of zoology. His seminal work in the 1970s used nonlinear dynamics to challenge the prevailing view that complex ecosystems were inherently more stable, demonstrating instead that increased complexity could lead to instability. This research, encapsulated in his influential book *Stability and Complexity in Model Ecosystems*, introduced key concepts like May's theorem and transformed population ecology. He later held professorships at Imperial College London and the University of Oxford, where his research expanded to include the dynamics of infectious diseases like HIV/AIDS and influenza.

Public policy and scientific advice

May's expertise was highly sought by governments and international bodies. He served as Chief Scientific Adviser to the UK Government and head of the Office of Science and Technology from 1995 to 2000, advising Prime Minister Tony Blair on issues ranging from BSE to genetically modified organisms. As President of the Royal Society from 2000 to 2005, he championed evidence-based policy on climate change and biodiversity, often speaking before the United Nations. He was also a founding author of the Millennium Ecosystem Assessment and served on the Scientific Advisory Council for the Prime Minister of Japan.

Awards and honours

May received numerous prestigious accolades for his scientific and public service. He was awarded the Crafoord Prize in Biosciences in 1996 for his fundamental contributions to ecology. He was knighted in 1996, becoming Sir Robert May, and was later elevated to the peerage as Baron May of Oxford in 2001. He was appointed to the Order of Merit in 2002. The Royal Society awarded him its highest honour, the Copley Medal, in 2007. He was a fellow of multiple academies, including the Royal Society, the Australian Academy of Science, and a foreign member of the US National Academy of Sciences.

Personal life and legacy

He married Judith Feiner in 1962, and they had one daughter. Known for his direct and sometimes combative style in defending scientific consensus, he was a formidable advocate for science in society. He died in Oxford in 2020. His legacy endures in the mathematical frameworks used to study ecosystem stability, epidemiology, and conservation biology, and in the model he set for scientists engaging with the policy process on global challenges.
