Pete profile

Dr Peter Taylor


Dr Peter Taylor (BSc, MBChB, MSc, MRCP) is a Clinical Senior Lecturer specialising in endocrinology and epidemiology at the University Hospital of Wales and Cardiff University. He received his undergraduate and medical degrees from the St. Andrews University and the University of Manchester. He undertook his core medical training at the two teaching hospitals in Edinburgh, before commencing specialist training in diabetes and endocrinology in Bristol, Bath and Cardiff. During his clinical training he received a prestigious MRC scholarship to undertake a masters’ degree in epidemiology at the London School of Hygiene and Tropical Medicine.


He undertook his PhD in thyroid epidemiology under Professor Colin Dayan and Professor Nicholas Timpson. His research has focused on the effects of common variation in thyroid status as well as thyroid hormone prescribing. In this work, he has also published the first whole genome sequence study to identify rarer variants associated with thyroid function and published the first Mendelian Randomization in thyroidology to better clarify the relationship between thyroid hormone and body composition.  He has also studied the impact of endocrine disruptors in pregnancy on offspring IQ and has examined the potential benefits of correcting mild – moderate iodine deficiency.


He has received awards at both national and international conferences for his work and has published in leading medical and endocrine journals including Nature Reviews Endocrinology, Lancet Diabetes and Endocrinology, JAMA, JAMA Internal Medicine, Nature Communications, Thyroid and the Journal of Clinical Endocrinology and Metabolism.
