I trained in Medicine at the Queen's University of Belfast and continue to work clinically at St John's Institute of Dermatology, Guy's and St Thomas' Hospital. I joined the School in 2011 having completed my PhD at the University of Nottingham and  gained post-doctoral experience as a visiting scholar at the University of Pennsylvania, USA.

I am currently funded by a Wellcome Senior Clinical Fellowship in Science

I am former Chair of the European Dermatoepidemiology Network Steering committee ( I am also co-Chair and co-founder of the REporting of studies Conducted using Observational Routinely collected Data (RECORD) initiative ( I am Associate Director for Health Data Research UK London (


Department of Non-communicable Disease Epidemiology
Faculty of Epidemiology and Population Health


Centre for Global Chronic Conditions


I teach on a number of courses at the School, and I am currently the co-Course Organiser for the Certificate of Pharmacoepidemiology and Pharmacovigilance (PEPI)


My research addresses two major areas:

  1. The epidemiology of skin diseases
  2. Reporting of observational research undertaken using routinely collected data

1. The epidemiology of skin diseases

My research addresses an important research gap, the causes, consequences and treatment of skin disease. Little is known about the epidemiology of skin diseases. My work focuses in particular on using the power of routine data sources to provide answers for important research questions. 

  • Eczema research  I am leading a programme of work on eczema using a variety of data sources. This work is supported by a Wellcome Senior Clinical fellowship in Science. I will identify eczema phenotypes using longitudinal population-based data and use a comprehensive approach to investigate if there are strong associations between eczema and major adverse health and social outcomes using large longitudinal population-based data. This cutting-edge work will make substantial contributions towards understanding eczema complexity and improving patient outcomes.
  • Other eczema-related work is focused on gene-environment interactions in eczema (in collaboration with the UK Translational Research Network in Dermatology), identifying costs and validating eczema diagnosis codes in UK general practice.

2.Reporting of observational research undertaken using routinely collected data

I co-founded the REporting of studies Conducted using Observational Routinely collected Data (RECORD) initiative ( ) in 2012 in order to create reporting guidelines for studies undertaken using observational routinely-collected data.
