About Me

My research interests focus on the roles mitochondria play in aspects of eukaryotic life, ranging from their origin, metabolism, biogenesis and role they play in cell death pathways.  These are interrogated using biochemical, molecular biology, genetic and cell biology techniques.  I incorporate these interests into classes I teach to provide an understanding of practical techniques and also the current literature in the field.  I am also a strong supporter of scientific communications and outreach to disseminate scientific developments and knowledge to a broader audience with the goal of increasing the general support of the scientific process. 



Ph.D., University of Bristol “Molecular characterisation of the mitochondrial permeability transition pore”, 2003
B.Sc., University of Leeds, Biochemistry with industrial placement, 1999
