Robert Griffiths was Fellow and Tutor in Mathematics at Lady Margaret Hall from 1998 to 2011. He was elected as Fellow of the Royal Society in May 2010.
Prof Griffiths was appointed to an Emeritus Fellowship in 2011.

Research interests:
Mathematical Population Genetics, particularly in modelling stochastic evolutionary processes and developing computational algorithms for ancestral inference from samples of genes, such as the time to the ancestor of the genes.
