Professor Thomas completed his PhD in the genetic epidemiology of hypertension at the Chinese University of Hong Kong in the Department of Medicine and Therapeutics. He then took up an academic post in 2002 in the Department of Public Health and Epidemiology (later the School of Public Health) at the University of Hong Kong to help coordinate the initiation of the Guangzhou Biobank Cohort Study.

In the summer of 2007, he took up the post of Reader in Epidemiology, Public Health and Biostatistics, now the Institute of Applied Health Research, of the College of Medical and Dental Sciences at the University of Birmingham. In 2017, he was made Professor of Epidemiology and Research Methods.  He is the Institute’s Director of Research Knowledge and Transfer. He is the Co-Director of the MSc Health Research Methods programme.

Professor Thomas is also Regional Director of the NIHR Research Design Service West Midlands.

Professor Thomas is interested in supervising doctoral research students in the following general areas:

• Determinants of cardiovascular disease, particularly atrial fibrillation,  morbidity and mortality.
• Approaches to attenuate cardiovascular disease and associated risk factors.

• Health consequences of air pollution.

RESEARCH ACTIVITY

Professor Thomas' research is at the cutting edge of understanding cardiometabolic conditions that place a significant burden on healthcare services and society as a whole. This understanding is coupled with intervention studies that inform disease prevention and patient care.

There are two main components to his research: Firstly, epidemiological studies which are designed to investigate environmental (air pollution, temperature), lifestyle (diet, physical activity, sleep) and genetic factors contributing to cardiometabolic disease risk factors (Type 2 diabetes, obesity, hypertension and dyslipidaemia) and associated morbidity (cardiovascular disease, eg atrial fibrillation, stroke) and mortality, and; secondly in the management and prevention of these conditions, using pharmacological agents and lifestyle/behavioural modifications. His contribution to the first component has resulted in greater appreciation of the pathogenesis of these diseases and has helped in development of more effective therapeutic interventions, which can be used intensively in those identified to be at greatest risk.  In this manner, the application of this scientific research has been directly used to alleviate morbidity and mortality in patients with these conditions and thus provide direct benefit.  Work related to the second component has led to a series of interventional studies targeting physical activity and diet and specific pharmacological agents in general populations and in specific patient groups to improve health indicators and reduce morbidity and mortality.

His work has been recognised as influential in healthcare as demonstrated by the publication in distinguished general medical journals such as the Lancet, Science and BMJ, as well as top specialist journals, including Eur Heart J, Atherosclerosis, Thrombosis and Vascular Biology, Stroke, and Diabetes Care.

Significant specific studies include:

NIHR Global Health Research Group on Atrial Fibrillation management(Co-PI)

Guangzhou Biobank Cohort study (http://ije.oxfordjournals.org/content/35/4/844.long) and CVD subcohort (Co-PI, http://www.nature.com/jhh/journal/v24/n2/full/jhh200952a.html)

30,000 subjects recruited over 3 phases to study the pathogenesis of chronic diseases. The first 6 year follow-up has now been completed with 18,000 revisiting the hospital and 2,400 deaths documented. Vital status has been determined in over 99%.

Elderly Health Centres Study

A prospective cohort of over 66,000 individuals, accounting for 9% of the 65 or older population from 18 Elderly Health Centres were established to deliver health examinations and primary care services for older adults in Hong Kong. Over 10,000 deaths have been documented (https://www.ncbi.nlm.nih.gov/pubmed/27197138).

Hong Kong Cardiovascular Risk Factor Study

A prospective cohort of 3,000 Chinese subjects for which 12 year follow-up data is now available (http://eje-online.org/cgi/content/full/155/4/623)
