Andrew Griffiths


My research utilises molecular approaches to investigate contemporary and historical patterns of genetic diversity. An interest in genetics has always fuelled my work as it provides a suite of tools which are not taxon specific and so can be applied widely, allowing researchers to investigate previously intractable questions in biology and evolution. That said, fish have been my biological system of choice, due to the variety of habitats they occupy, their intimate contact with the aquatic environment and commercial & conservation significance of many species.

Andrew is a lecturer in the department of Biosciences and is based at the University's Streatham campuse-mail:
