Research overview

My interest in science started back when I was at school in Rutland.  I went on to study A-levels in biology and chemistry before moving on to attend Oxford Brookes University where I studied for a BSc in Human Biology.  My first science job was working for a genetics company (OXAGEN), were I stayed for 5 years before coming to OCDEM in 2004.

When I first joined OCDEM I worked on a large EU funded project (MolPAGE) led by Professor Mark McCarthy which aimed to identify biomarkers (proteomic, metabolomic, transcriptomic) relevant to type 2 diabetes.  My primary role was establishing sample collection and storage standardisation.  I was able to build on this experience as part of a subsequent collaborative effort, the MuTHER consortia,  where one of the aims was to investigate the genetic control of gene expression across multiple tissues using various samples taken from the UKTwin BioResource.

In 2011 I joined Professor Gloyn’s group and since then have been supporting a range of research projects.  Currently I am investigating the impact of nonsynonymous variants in the glucokinase (GCK) and glucokinase regulatory protein (GCKR) genes on the function of these key regulators of insulin secretion & glucose disposal.

Outside of work I enjoy running/jogging and was pleased to have recently completed the Oxford Half Marathon 2014.   I am also a member of the PTA for my children’s school as well as the secretary for the Minster Lovell scouting groups and help to organise the kitchen for the Oxford RFC mini and juniors.
