Ruth Andrew holds a Chair in Pharmaceutical Endocrinology at the University of Edinburgh and directs the Clinical Research Facility Mass Spectrometry Core. After qualifying as a pharmacist in 1990, she studied for a PhD in the field of pharmaceutical analysis, using gas chromatography mass spectrometry as an approach to profile catecholamines in hypertension. In 1994, she joined the Endocrinology Unit in the University of Edinburgh to develop further interests in mass spectrometry and establish its use in steroid profiling in cardiovascular disease. Since then Ruth has investigated the regulation of glucocorticoid metabolism and her group has focused on the role of hepatic 5α-reductase in diabetes and in dynamic methods to quantify these metabolic pathways in vivo using stable isotope tracers. She leads a team specialising in small molecule quantitative analysis in support of translational medicine, most recently investigating the use of mass spectrometry imaging in steroid analysis. She takes an active role in teaching both Honours students (Endocrine Physiology and Pharmacology, Clinical Biochemistry) and post-graduate students. Ruth contributes to University governance though acting on the University Post-graduate appeals committee. She is the General Secretary of the Society for Endocrinology and acts on grant panels for the Chief Scientist Office, FWO (Flanders), NCN (Poland) and the Commonwealth Commission. She is a Reviews Editor for the British Journal of Pharmacology, a Specialty Chief Editor for Systems Endocrinology (Frontiers in Endocrinology) and an Associate Editor with Talanta.
