INTERESTS:
I lead a multidisciplinary geomicrobiology group working at the interface between biology and geology. Our research focuses on the mechanisms of microbial metal reduction, with emphasis on the environmental impact and biotechnological applications of Fe(III)-reducing bacteria. See www.geomicrobiology.co.uk for more details
