Biography
Mark has a BSc and a PhD Chemistry from The University of Aston where he studied from 1988-1994. He moved to take up a post-doctoral position at Cambridge University with Prof. Richard Perham FRS, where he moved into biological NMR, before becoming Facility Technical Officer at The University of Kent in 1997. He became NMR Facility Manager at the Medical Research Councul Centre for Protein engineering (MRC CPE) at Cambridge, under the directorship of Prof. Sir Alan Fersht FRS before taking a brief spell in industry working on the NMR method development of DNP Hypersense for metabolism applications. Mark returned to Kent as NMR Facility Manager in 2001 and was promoted to academic status in 2005 and gained a postgraduate certificate in higher education (PGCHE) from Kent. He stayed at Kent for 15 years before moving to UWA in May 2016.

Roles, responsibilities and expertise
Mark is the Academic Lead of the CMCA NMR Facility housed in the School of Chemistry and Biochemistry and UWA where he uses NMR method development to answer specific questions.

He has over 25 years of expertise in NMR spectroscopy that has included proteins, peptides, natural products and metabolomics. He has solved several structures of proteins and studied protein-ligand interactions using ligand-observe and protein observe methods using 1H, 13C, 15N, 31P and 19F NMR. Ligand-observe approaches are of special interest in the field of pharmaceutical drug discovery.

Mark also uses NMR spectroscopy to study dynamic processes in molecules in solution and has extensive experience in measuring nuclear relaxation properties and applying such data to timescales and exchange phenomena.

His is also developing applications of 19F NMR as a specific probe for both biology and chemistry. He has developed 19F NMR to monitor protein-ligand binding and physical properties using fluorinated species.

Mark is keen to use NMR spectroscopy to answer new scientific questions and promotes utility of this technique; please contact him if you think NMR can help your research project or technical questions.

Current projects
1.Enhancing ligand-observe NMR spectroscopy for pharmaceutical drug discovery and protein-ligand interactions. The main thrust is the development of quantitative NMR approaches to increase efficiency in the drug-discovery pipeline.

2.Using NMR spectroscopy as a quality control tool in pharmaceutical product analysis. Liquid and solid-state NMR spectroscopy provides excellent tools to study pharmaceutical formulations and probe the effects of preparation and storage of drugs prior to dispensing and use.

3.This research involves the development and application of NMR in metabolism and metabolomics research. Our interests cover a wide variety of projects with medical, biological, ecological and consumer applications to identify markers that flag important changes. For example, changes due to disease, nutrients, environment or batch production.

4.NMR and biophysical characterisation of thioredoxin (Trx) proteins involved as disulphide bond catalysis and protein-folding chaperones in the endoplasmic reticulum (ER). Protein folding in the ER is of great interest in fundamental biochemistry as well as the biopharmaceutical industry as it directly correlates to antibody drug production. Structure-function studies of Trx proteins using protein-ligand interactions, 19F biological NMR, dynamic NMR and other approaches in order to understand the molecular bases of ER protein operation.
