Dr Rueyleng Loo

Senior Lecturer

Medway School of Pharmacy


Rueyleng graduated from the University of Bradford with a first class honours degree in Pharmacy.  She then completed her pre-registration training at the GlaxoWellcome (currently known as GlaxoSmithKline) and Southend General Hospital. Once qualified, she worked as a hospital pharmacist for several years before she undertook a PhD in Biological Chemistry at the Imperial College London. Upon completion of her PhD, she held a postdoctoral research position there for a year.

Subsequently, Rueyleng joined Medway School of Pharmacy as a Clinical Lecturer in Pharmacy Practice and then promoted to a Senior Lecturer.  She is currently the School’s MPharm Placement Coordinator and a Module Convener for one of the year 3 integrative therapeutic module (PHAM 1130).  She also holds an Honorary Clinical Lectureship at the Imperial College London, Section of Biomolecular Medicine (since 2009).

Rueyleng jointly leads the Medway Metabonomics Research Group (MMRG) with Professor Jeremy Everett at the School of Science. She is a member of the Clinical and Professional Practice group and Renal and Cardiovascular Physiology and Pharmacology research group.

Rueyleng's main research focuses on the discovery of metabolic biomarkers of cardiovascular diseases in human population studies.  She also investigates the effects of diets and physical activities on health in general. More recently, she has extended her research in personalised healthcare and established a track record in the development of chemometric and statistical methods for analysis of ‘omics’ data and biomarker recovery.

In collaboration with Prof. Holmes and Prof Nicholson, Imperial College London, we have developed novel methods for analysing metabonomics datasets. Details of these algorithms have been published and we have provided the encrypted matlab scripts as links in the section below.

Statistical HOmogeneous Cluster SpectroscopY (SHOCSY)

SHOCSY is a clustering approach which aims to remove interferences within metabonomic datasets. In so doing, it improves the predictive ability of the model and enhances the reliability of biomarkers.

Details of the approach have been published in Analytical Chemistry (doi:10.1021/ac500161k).

A description of the SHOCSY algorithm and a link to the downloadable package are also available here.

Automatic Spectroscopic data Catergorization by cLustering Analysis (ASCLAN)

ASCLAN is a clustering approach which aims to reliably distinguish discriminatory metabolites from non-discriminatory metabolites within metabonomic datasets that contains two biological classes.

Details of the approach have been published in Analytical Chemistry (doi:10.1021/acs.analchem.5b04020).

A description of the ASCLAN algorithm and a link to the downloadable package are also available here.
