Biography

I completed my first degree in Chemistry at the University of St. Andrews. I then moved to UMIST to undertake my PhD under the supervision of Noel McAuliffe on the development of manganese Schiff base complexes as biomimetic models for which I was awarded the inaugural Laurie Vergnano Award by the Royal Society of Chemistry (now the Dalton Young Researcher’s Award) in 1994. I then moved to the University of Santiago de Compostela, Spain funded by a Royal Society Postdoctoral Exchange Fellowship. I then returned to UMIST to work with Andy Whiting on the development of route to conformationally restricted biaryl systems and was also appointed to an honorary lectureship.

In 1998 I was appointed as Lecturer in Inorganic Chemistry at Queen Mary and Westfield College (now Queen Mary University of London) and was promoted through the ranks to Professor of Synthetic Chemistry in 2010. In 2012 I became the Deputy Dean for Research for the Faculty of Sciences and Engineering and in 2016 the Director of the QMUL Doctoral College. I moved to Keele in 2018 to become Head of School.

Research and scholarship

Our independent research has focussed on the design of ligands for functional complexes for many years and the two main areas of current interest are the design of manganese complexes for application in oxidative catalysis and the generation of small molecule fluorescent probes for the detection of mobile zinc in cellulo.

We have a long-standing interest in the application of biomimetic manganese complexes in oxidative catalysis for applications in both synthetic chemistry and in low temperature laundry. Here the main drive has been to develop systems capable of oxidising hydrocarbon substrates with good selectivity and in high yield using the environmentally benign oxidant hydrogen peroxide. Recent highlights have shown that additive ligands and Lewis acids can have a profound effect on catalyst activity, significantly modifying the reactivity and behaviour of the system under investigation.

Our man focus of activity in recent years has been on the development of small molecule fluorescent probes for the detection of ‘mobile’ zinc. This is the second most abundant d-block metal in humans and whilst much of the element is present in bound forms, there exists a pool of ‘mobile’ or ‘free’ zinc whose concentration varies enormously in cells. The element’s concentration is controlled by a complex network of 24 transporter proteins and it is known that abnormal variation in its levels is associated with a number of important disease states including type II diabetes mellitus, certain cancers, age related macular degeneration and there has even been a recent link with dietary zinc intake during pregnancy and autism. Owing to its d10 configuration and lack of spectroscopically useful nuclei, it is generally imaged using fluorescent probes. We have focussed our efforts on the development of small molecule probes that use a switch off of Photo-induced Electron Transfer (PET) as a detection mechanism. Recent highlights include the development of a number of probes able to target specific cellular space and to specifically image breast cancer cells. We have also developed, in collaboration with Steve Goldup, now based in Chemistry at the University of Southampton, (https://www.southampton.ac.uk/chemistry/about/staff/sg17g14.page) a series of rotaxane systems capable of selectively detecting zinc. We are also actively engaged with a pan-European collaborative network of scientists interested in zinc, Zinc-Net (https://zinc-net.com), that was established following support through TD1304 COST Action (https://www.cost.eu/actions/TD1304/#tabs|Name:overview).

We also have had a long-standing collaboration with Steffi Krause (https://www.sems.qmul.ac.uk/staff/s.krause) from The School of Engineering and Materials Science at Queen Mary, University of London. Here our collaborative research has focussed on two main areas: i) Biosensors and ii) Electrochemical imaging. In both cases we use synthetic chemistry to develop materials capable of delivering functional applications in real world settings. Our biosensor research has sought to develop disposable biosensors for the detection of enzyme activity based on the enzymatic degradation of thin polymer films. Film degradation in the presence of an enzyme is monitored using impedance spectroscopy and a Quartz Crystal Microbalance (QCM). Current efforts are directed to the development of polymers that are degraded specifically by different proteases, which are frequently at elevated levels in cases of inflammation and bacterial infection. Biosensors with the primary goal of monitoring inflammatory conditions such periodontal disease and multiple sclerosis have recently been successfully developed. Our research in electrochemical imaging uses ‘click’ chemistry to modify surfaces to allow image generation using Light-Addressable Potentiometric Sensors (LAPS) and Scanning Photo-induced Impedance Microscopy (SPIM). These techniques are based on photocurrent measurements at electrolyte/insulator/silicon (EIS) field-effect structures and are capable of measuring local changes in the surface potential (LAPS), which can be used to image ion concentrations, and of measuring the local impedance (SPIM). LAPS and SPIM have great potential as tools for functional electrochemical imaging of the attachment area of cells, providing information such as ion concentration, extracellular potentials and cell impedance.
