The Buchanan Medal 2022 is awarded to Professor Richard Moxon FMedSci FRS for helping pioneer the field of molecular microbiology; discovering contingency loci in bacteria that facilitate rapid evolution under selection and making key contributions to the development of meningitis vaccines.

The award

The Buchanan Medal is awarded for distinguished contributions to the biomedical sciences. The award was created from a fund to the memory of the physician George Buchanan FRS (PDF), former Chief Medical Officer of the UK, and was first awarded in 1897. The medal is of silver gilt, is awarded annually and is accompanied by a gift of £2,000.


The Buchanan medal is open to UK/Commonwealth/Republic of Ireland citizens or those who have been residents for three or more years. There are no restrictions on career stage and nominations will remain valid and shall be considered by the award selection committee throughout three nomination cycles. Teams or groups may now be nominated for this award.


Nominations for this award will open in November 2023.
