Professor Frances Williams

Frances runs her own research group studying the genetic epidemiology of common complex traits related to rheumatic diseases. In particular, her research focuses on chronic pain syndromes including low back pain and intervertebral disc degeneration (IDD). This ties in well with her clinical role as Hon Consultant Rheumatologist at Guys and St Thomas’ NHS Foundation Trust.

Frances also runs an NHS clinic for Musicians and Performing Artists, many of whom have chronic pain conditions, which threaten their occupational wellbeing. She has led several of the world’s first GWAS studies as well as the largest to date study of back pain, demonstrating that many of the environmental risk factors (e.g. social class) share a genetic predisposition with back pain.

Fran started working with TwinsUK in 2002. She became a full time TwinsUK researcher as Rheumatology Registrar/Senior Research Fellow in May 2003.

Christel Barnetson

Christel has been a member of the Department of Twin Research since 1994 and has been involved with the Research Grants and Finance Management of the Department of Twin Research over the past 15 years.

Christel is responsible for budgeting all new research projects and managing all research funding. She is also an active member of the TwinsUK Research Executive Committee.

Ayrun Nessa

Ayrun has been an integral member of TwinsUK for 14 years initially working as a Lab Assistant. Later Ayrun joined the Clinical Research Team as Research Assistant, ultimately progressing to her current role, leading and overseeing twin visits.

Ayrun has been a key member in improving twin visits, developing, implementing and rolling out new visit structures, working with all teams within the DTR to develop and pilot new research tests, and most importantly ensuring that all ethical and legal standards are strictly maintained.

Ayrun has seen many changes over the years, from booking twins using handwritten diaries to the electronic systems we use now. Twin visits remain Ayrun’s favourite part of her job, particularly seeing the twins more than once over the years on repeat visits.

Professor Tim Spector

Tim Spector is a Professor of Genetic Epidemiology at King’s College London and Honorary Consultant Physician at Guy’s and St Thomas’ NHS Foundation Trust. Tim founded TwinsUK in 1992, which is now one of the richest collections of clinical data in the world. He is also an expert in personalised medicine and the gut microbiome. Tim is the lead researcher behind the world’s biggest citizen science health project – the Covid Symptom Study app, for which he was awarded an OBE.

Through his work he has been given many awards and prizes and is a Fellow of the Royal Society of Biology and the Academy of Medical Sciences. He has published over 900 scientific papers and is ranked by Google as being in the top 100 most cited scientists in the world. He has published four popular books, including the best-selling Diet Myth, Spoon-Fed, and more recently Food for Life – a Sunday Times bestseller. He makes regular appearances in the media.

Dr. Deborah Hart

Deborah is a genetic epidemiologist by training and has managed several large-scale population cohorts. Before working at the DTR she set up and co-ordinated the Chingford 1000 Women Study, a longitudinal cohort into the natural history and genetics of musculoskeletal disease.

Deborah has been Executive Director of TwinsUK since 2009. She set up data sharing and governance processes which has led TwinsUK to share data and samples with over 800 collaborators, resulting in around 100 publications a year. She also set up our Voluntary Advisory Panel of twin volunteers.

Deborah oversees the day to day aspects of running TwinsUK including operations, ethics and governance, cohort attrition, dissemination and engagement, budgets and staffing. She is also responsible for maintaining our core funding.

Dr Jordana Bell

Jordana Bell leads the epigenomics research group at the Department of Twin Research and Genetic Epidemiology at King’s College London. Her research explores the (epi)genomic basis of complex diseases in human populations, focusing on intermediate phenotypes including epigenomic and gut microbiome variation. The broad aim is to apply computational approaches to characterise the biological processes underlying human ageing and age-related cardio-metabolic disease risk, onset, and progression.

Jordana completed her doctoral studies on genetic interactions in human complex traits at the University of Oxford. She was subsequently a Wellcome Trust funded fellow at the Universities of Chicago and Oxford, where her work shifted towards human epigenomics.

Since joining King’s in 2012 Jordana has established a research programme in human population epigenomics and is currently leading research efforts across UK and international collaborative projects, including within DIMENSION, ESSN, GoDMC, and CHARGE consortia. Jordana’s primary research focus is to understand the processes shaping epigenetic variation in human populations, and its biomedical significance. Further projects explore computational approaches for integrative analyses of high-dimensional biomedical data (environmental exposures, DNA sequence, DNA methylation, metabolomics, microbiome, and phenotype) – for prediction of future disease, towards implementing stratified medicine.

Jordana is coordinator of the JPI ERA-HDHL funded DIMENSION consortium on dietary impacts on the epigenome and transcriptome in context of metabolic health.

Professor Kerrin Small

Kerrin is a Professor at King’s College London and Deputy Director (Scientific) of the TwinsUK Resource. Her research investigates the genetic regulation of gene expression across tissues, time and environments. She has explored the relationship between genetic variants, gene expression in fat tissue and obesity-related traits and uncovered links between gene expression and type 2 diabetes.

Kerrin obtained a PhD in Genetics from Stanford University and undertook post-doctoral training in complex trait genetics at the Wellcome Centre for Human Genetics at the University of Oxford. She joined the Department of Twin Research in 2009 and directs transcriptomic research within TwinsUK.
