Sir Michael Gideon Marmot (born 26 February 1945) is Professor of Epidemiology and Public Health at University College London.

[4] Marmot has led research groups on health inequalities for over thirty years, working for various international and governmental bodies.

[8][9] He earned an MPH degree in 1972[8] and a PhD in 1975 from the University of California, Berkeley for research into acculturation and coronary heart disease in Japanese Americans.

He leads the English Longitudinal Study of Ageing (ELSA), and is engaged in several international research efforts on the social determinants of health.

His department includes the MRC National Survey of Health & Development, a longitudinal study directed by Professor Michael Wadsworth of people born in Britain in 1946 and followed up since.

He served on the Scientific Advisory Group of the Independent Inquiry into Inequalities in Health chaired by Sir Donald Acheson, the former UK chief medical officer.

[30] Published in the same year, Build Back Fairer: The COVID-19 Marmot Review explored connections between inequality in socioeconomic conditions and COVID-19 death tolls, recommending investing in public health.

[33] In 2022, Marmot warned of the risk of "a humanitarian crisis" the next winter caused by "fuel poverty", which could have long-term consequences mostly for the young and least well-off.
