Peter James Green, FRS (born 28 April 1950)[1] is a British Bayesian statistician.
Until 2024, he was a Professorial Research Fellow at Bristol, and until 2022 a distinguished professor at the University of Technology, Sydney.
[2] In 2024, Green had publicly questioned the usefulness of specific evidence in relation to the case of Lucy Letby, who was convicted of the murder of a number of babies in her care, namely the staff rotas and blood samples from babies who had collapsed with low blood sugar.
[3] However lawyers for the affected families declared during the subsequent hospital inquiry into the neonatal deaths that he and others questioning the conviction "should be ashamed of themselves".
He served as president of the Royal Statistical Society from 2001 to 2003,[5] having previously been awarded its Guy Medal in both Bronze (1987) and Silver (1999).
