Research Interests

I have worked in a large number of interesting areas. My current areas of research are summarised below. The references refer to my list of publications.

Cell signalling

I am studying the localisation of Ras proteins to different lipid bilayers and what modulates their binding. This is a difficult non-equilibrium process and spans a large range of length and time-scales

Ion channels

Ion channels are exquisitely-sensitive protein machines which selectively conduct ions at often high rates and are able to open and close their pores in response to a wide range of stimuli. Molecular simulation is a vital way of improving our understanding of these subtle proteins. I have studied the selectivity of K channels [11] and am working with Stephen Tucker and Thomas Baukrowitz on Kir1.1. [9,10,13,14,16]

Peptide transporters

hPepT1 is a member of the SLC15 family and transports di- and tri-peptides across the lining of the gut and is one of the main routes how we absorb dietary nitrogen. They also transport a wide range of drugs including some beta-lactam antibiotics, valacyclovir and L-Dope-Phe. I am working with Simon Newstead to understand how bacterial homologues transport di- and tri-peptides [17, 18] with the ultimate aim of developing a computational process that can predict chemical modifications to drug scaffolds that improve their bioavailability, by increasing their transport by hPepT1.

e-Infrastructure and grid computing

I have had a long interest in developing novel methods for accelerating calculations using grid computing [2,3,5,8]. I am also a Co-Investigator on the EPSRC SeIUCCR project whose aim is to encourage the use of e-Infrastructure within the UK academic community.

Blog

I keep a blog - please see this page.

Teaching

I lecture the first-year biochemists on non-covalent interactions and protein-folding and have run a workshop on ABC transporters for the fourth years. I give revision mathematics tutorials to the first-years when required. I am keen to try innovative ways of teaching and have used Mendeley to encourage undergraduates to read the primary literature. I am also arranging the first Software Carpentry workshop in Oxford to help researchers improve their core computational skills - please see my blog posts.
