Graham Hitman graduated from University College Hospital Medical School in 1976 and did his clinical training in General Medicine and Diabetes in Kings College and associated Hospitals, St Bartholomew’s Hospital and subsequently The Royal London Hospital. He did his MD research into the genetics of diabetes with Professor David Galton at Barts and was subsequently appointed as Lecturer, Senior Lecturer and Reader at the Royal London Hospital Medical College working under Professor RD Cohen. Since 1995 he has been Professor of Molecular Medicine and Diabetes at Barts and The London School of Medicine and Dentistry. Prof Hitman was director of the Blizard Institute (2013 to 2017) and Editor of Diabetic Medicine (2009-2015).

Research Interests:

Graham Hitman’s main research interests are the

  • genomics of diabetes,
  • prevention of diabetes and its complications
  • clinical decision theory.

The current focus of his work is the gene environmental interaction in pregnancy and its relation to future cardiometabolic disease in the offspring in South Asian people (previously funded by an FP7 EU grant) and the application of Bayesian models to help inform clinical decision making in gestational diabetes and COVID-19 (funded by EPSRC).

He has led several seminal clinical trials including as one of the principal investigators of the CARDS trial that has influenced the development of current lipid lowering guidelines in diabetes.

He currently has 337 peer reviewed publications listed in PubMed. Hitman Google scholar entry (March 2020) shows 50,405 citations and an h-index of 81.
