I joined the School of Life and Health Sciences in January 2011, after 17 years as an academic member of staff at the University of Strathclyde. I worked in several different departments there, starting in Chemistry, then moving to Immunology, Bioscience, and lastly Strathclyde Institute of Pharmacy and Biomedical Science. This reflects my broad scientific background and interests in oxidative stress ranging from molecular processes to inflammation in disease.
I have extensive collaborations in Europe: currently I am treasurer of the Society for Free Radical Research (Europe), a workgroup leader in the COST Action CM1001 on “Chemistry of non-enzymatic protein modification”, and a member of the International HNE-Club committee, having just stood down as secretary.
I have taught extensively in biological and biomedical related classes at the University of Strathclyde, where my primary focus was on biochemistry, metabolism and molecular events in cardiovascular disease. I have also been an invited lecturer for the Masters in Integrative Physiology at the University of Barcelona, and have lectured at the Spetses Free Radical Summer School run by the Society of Free Radical Research Europe.

Here at Aston University, I am currently only involved in teaching key skills tutorials for BY1KS1 and BY2KS2. However, previously at the University of Strathclyde I taught a wide range of lecture- and laboratory-based classed, mainly in the biochemistry and biomedical science areas.
All my current research is in the field of oxidative stress. I have been working on this subject since 1994, when I moved to the University of Strathclyde. Oxidative stress occurs when the level of free radicals or oxidants in a system exceeds the capacity of antioxidants to protect against them. This can lead to oxidative damage, thus harming the cell or tissue. This often happens in inflammation, which occurs in infectious diseases as well chronic diseases such as cardiovascular disease, diabetes, cancer, and neurodegenerative diseases. These diseases are a major cause of ill-health and mortality in all developed countries, and increasingly in developing countries.
Oxidants are formed in many metabolic and environmental processes. They are also be released by phagocytes during their role in early immune defence against pathogens, but in severe inflammation may result in host tissue damage and pathology. I am interested in various aspects of oxidant metabolism, from mechanisms of cell killing by oxidants and cell antioxidant defence to the role of immune cell-derived oxidants in disease and immunomodulatory effects of oxidised macromolecules. Much of the research in my group relates to cardiovascular disease (CVD) and atherosclerosis, conditions where oxidative stress is clearly implicated in the pathology of the disease, through the increased cellular uptake of oxidized low density lipoprotein (LDL). One of the major techniques used is electrospray mass spectrometry (ESMS), which can be applied to the analysis of phospholipid and protein oxidation. Together with Prof Andy Pitt, we are currently establishing a new, state-of-the-art mass spectrometry facility in Life and Health Sciences.
Specific Research Areas
1. Oxidized and Chlorinated Phospholipids
Polyunsaturated phospholipids are particularly susceptible to oxidation by free radicals and also by the phagocyte-derived oxidant hypochlorous acid (HOCl). In early work we developed liquid chromatography electrospray mass spectrometry as an informative method for detecting specific oxidized phospholipids both in LDL and cells. Improving methodology for ox-phospholipidomics is still an area of interest, but the major focus now is on the biological effects of oxidized and chlorinated phospholipids. The responses of cells to lipid oxidation products such as oxPAPC, oxysterols, chlorohydrins of phosphatidylcholine and 4-HNE are have been investigated in cultured cells and a physiological model of vascular cell adhesion. We are especially interested in the way these compounds are recognized by cells, and the balance of pro-inflammatory versus anti-inflammatory effects. We have also been working on the biophysical effects of these compounds on biological membranes.
2. Novel MS methodology for detecting protein oxidation
Protein oxidation causes cellular dysfunction and is thought to contribute to a variety of chronic diseases. We have been developing advanced mass spectrometry (MS) methodologies for detecting specific types of oxidative protein damage, for example by hypochlorous acid or peroxynitrite, using MS2 and MS3 precursor ion scanning techniques. We are currently interested in applying this to protein dysfunction in ageing and arthritis. We are also expanding the approach to look at lipid peroxidation product adducts with proteins, especially in LDL and ageing tissue. This is currently a major focus of my research.
3. Effects of oxychloro compounds on cells
Oxidants similar to those released by phagocytes are also used as preservatives in many preparations for ocular application, e.g. sodium chlorite (NaClO2). Previously, we have looked at the differential effects of oxidants and other preservatives on ocular cells and pathogens, with a focus on understanding the basis of antimicrobial action and mammalian cell toxicity. We are currently using Saccharomyces cerevisiae as a model to investigate the role of antioxidants in protection against oxychloro compounds (HOCl and NaClO2) in a collaborative project with Prof Grzegorz Bartosz in Poland.
