Medway Metabonomics Research Group (MMRG)


Dr Ruey Leng Loo, together with Professor Jeremy Everett and Professor Frank Pullen, have recently formed a Medway Metabonomics Research Group (MMRG).  Metabonomics is concerned with the metabolic profiling of people, animals or other organisms in order understand the impact of genetic changes, environmental changes, clinical interventions or exercise. Pharmacometabonomics is a new branch of metabonomics that is concerned with the prediction of the effects of drugs on a person or animal, based on an analysis of their pre-dose metabolic profile. It is predicted to have much future importance for personalised medicine.

Purpose of the MMRG and Facilities

The main purpose of the MMRG is to develop and strengthen metabonomics and pharmacometabonomics capabilities in this region. The analytical facilities available to this group include 4 nuclear magnetic resonance spectrometers (1 x 500MHz, 2 x 400MHz and 1 x 300 MHz) and 10 mass spectrometers (2 x LC-MS, 2 x LC-MSMS, 2 x GC-MS, 1 x LC-Qtof –MSMS, 2 x LC-ion mobility Qtof MSMS and 1 x MALDI).  In addition, we use advanced computational and statistical methodologies to help analyse the metabonomics data.


Our current projects involve the utility of metabonomics in the study of Cardiovascular disease, Diabetes and Exercise, Nutrition and Obesity.

We welcome suggestions for new projects, collaborations and consultancy.

OmniHeart Metabonomics Study

This project focuses on metabolic phenotyping using high-resolution spectroscopy of urine samples from the OmniHeart study.  The global aim of this project is to identify the impact of different dietary interventions on the urinary metabolic phenotypes and to investigate specific urinary biomarkers associated with blood pressure and other cardiovascular disease risk factors, using the metabolomics-wide-association approach.

This project is collaboration between Medway School of Pharmacy, Imperial College London and The Johns Hopkins University.  Ruey Leng is the lead of this MRC-funded project. This project is supported by a post-doc, Xin Zou, and a part-time technician, Viktorija Kuziene.

Diabetes and Exercise Metabonomics and Pharmacometabonomics Study

This project focuses on the metabolic profiling of urine and plasma samples from diabetic patients. The aim of the project is to evaluate and predict the efficacy of various combined drug and exercise regimes on the clinical outcomes for these patients.

This project is led by Jeremy Everett in collaboration Professor Stefano Balducci and Professor Silvano Zanuso at the University of Rome, Italy.



In addition to Professor Everett, Dr Loo and Professor Pullen, the members of this group also include a full-time research associate, 5 full-time PhD students and 2 part-time PhD students/part-time technicians.

Research Fellows

tracey yip
Xin Zou

Xin Zou got his PhD degree in statistical signal processing from the University of Birmingham. He worked in the same department for another two years as a research fellow. Then he changed his research interest to bioinformatics and took two postdoc positions in Ulster University and Sheffield University, respectively, before he came to Kent University. He is currently working as a bioinformatician in the Medway Metabonomics Research Group (MMRG). His main job is to analyse the NMR and MS metabolomics data collected in the group.

Research Interests

His principal research interests lie in the field of bioinformatics, omics data processing (e.g. metabolomics, proteomics and transcriptomics), statistical signal processing, machine learning, pattern recognition and computational neuroscience (neural network dynamics modelling study).

Tracey Yip

Tracey completed her BSc and MSc at the University of Glasgow, focusing on spectrometric analysis of toxins in biological samples in Forensic Toxicology. Following this, she started her PhD at the Medway School of Pharmacy in October 2011 in collaboration with our partners at the Johns Hopkins University. Her project aims to examine how different healthy diets can cause alterations in the participants’ metabolic profiles. Additionally, Tracey has an interest in drug use and detection. She was involved in analysing athletic samples for prohibited substances during London Olympics (2012).

pat wright
Patricia Wright

After graduating from the University of Birmingham with a BSc in Medical Biochemistry, Pat went on to undertake a Master’s degree in drug metabolism at Bradford University. In the subsequent years she built a career in the UK pharmaceutical industry, initially at GSK and then Pfizer, as a bioanalytical HPLC and mass spectrometry specialist. Pat has extensive experience of both qualitative and quantitative analysis of pharmaceutical molecules in biological matrices, having held the positions of team leader within the quantitative bioanalytical group and then scientific lead for metabolite identification.

Pat has always been interested in the fundamental mechanisms of ionisation and fragmentation in mass spectrometry and has a number of publications in this field. Pat started her PhD in 2012 and her project will build on her previous experience in understanding MSMS fragmentation, particularly the thermodynamics behind bond cleavages. The thermodynamics will be modelled using Density Functional Theory, a quantum mechanics based software tool which helps determine the site(s) of protonation of the molecule in the gas phase and then predicts the effect protonation will have on bond length and other molecular parameters.
