Laura Horsfall PhD, Research Associate
Laura joined the PCPH department in early January 2009 as a Research Associate in Clinical Database Research. With a background in genetics and health services research, Laura is currently using THIN data to look at the epidemiology and outcomes associated with a common genetic condition. The work will form the final chapter of her PhD thesis in Human Genetics, which she has been undertaking part-time at the UCL Department of Genetics, Evolution and Environment since 2005. She is also involved with developing standard operating procedures for undertaking research using primary care databases.
Ruth Blackburn MSc, PhD Student
Ruth started a full time PhD in September 2012 and is working on the PRIMROSE programme, which is jointly led by the departments of Mental Health Sciences and Primary Care and Population Health. PRIMROSE is a 5 year National Institute for Health Research funded programme to investigate cardiovascular disease risk in people with severe mental illness; Ruth’s PhD will focus on using THIN data to explore inequalities in the provision of cardiovascular interventions to people with severe mental illness. Ruth has an MSc in Public Health and previously worked as an epidemiologist for the Health Protection Agency.
Shuk-Li Collings BSc, PhD Student
Shuk-Li is a full-time PhD student in the department. She joined in October 2010 on a MRC Industrial CASE studentship which is in collaboration with CSD MR UK. Her background is in statistics however her project is an epidemiological study which uses THIN to investigate the effects of using antiepileptic drugs in pregnancy on the mother and child. Her previous experience with THIN includes working with Dr Irene Petersen on a study of prescribing patterns of antidepressants in pregnant women.
Sonia Cotton, BSc, PhD Student
Sonia is a first year PhD student using The Health Improvement Network (THIN) data to research the risk of diabetes in pregnancy. Sonia was awarded an NIHR School for Primary Care Research studentship to undertake a PhD with the supervision of Dr Irene Petersen and Professor Irwin Nazareth.
After obtaining a BSc (Hons) in Mathematics, Statistics and
Operation research from Cardiff University, Sonia completed an MSc in
Medical Statistics at The London School of Hygiene and Tropical
Medicine. Following this Sonia was appointed as a Medical Statistician
at Imperial College London in the National Heart and Lung Institute
working on an international study investigating chronic obstructive
pulmonary disease (COPD).
Hilary Davies RD, MSc, PhD Student
Hilary started her PhD at the Primary Care and Population Health Department in October 2012. Her PhD will focus on maternal alcohol and illicit drug intake and neonatal abstinence syndrome. She will be analysing a linked cohort using THIN and HES data. Qualitative studies will also be conducted to examine primary care recordings and maternal perceptions of moderate alcohol and illicit and non-illicit drug use during pregnancy.
Hilary’s PhD is being funded by a scholarship from the NIHR School of Primary Care Research. She has a research MSc and has previously worked as registered dietitian in the NHS and lecturer at St Mary’s University College, London.
Sarah Hardoon PhD, Research Associate/ Statistician
Sarah joined the THIN research group in May 2011. Her current work is focussed on cardiovascular
diseases, particularly in relation to mental health. In particular, she is working on a research
study to develop and validate a cardiovascular disease risk prediction tool
specific to patients with severe mental illness, using the THIN database. She
is also working on a project to examine how cardiovascular risk factors may be
associated with dementia risk. Sarah has
an MSc in Medical Statistics and a PhD in Epidemiology/ Applied Medical
Statistics on analysing time trends in coronary heart disease and type 2
Rebecca Lodwick MSc, Research Associate
Rebecca joined the THIN research group in January 2013 to work on a project with the Marie Curie Palliative Care Research Unit, using THIN data to study the health of cohabitees of terminally ill patients. She was previously based in the HIV Epidemiology & Biostatistics group at UCL.
Louise Marston PhD, Senior Research Statistician
Louise joined the Department of Primary Care and Population Health in August 2008 after previously working at Brunel University and St George’s, University of London. Since then she has worked on a number of studies using THIN. She has looked at missing data in THIN data. Currently she is working on a project looking at antipsychotic use and their relationship with physical health.
Rachel McCrea PhD, Research Associate
Rachel joined the THIN research group in April 2013 after completing a PhD at the UCL Mental Health Sciences Unit. She is currently working on a project using the THIN database to look at the risks and benefits of psychotropic medication taken during pregnancy. Her PhD was in the field of psychometric epidemiology: in this she investigated whether hybrid latent variable models that combine continuous and discrete latent variables (factor mixture models) can be useful for resolving controversies surrounding the classification of psychiatric disorders, in particular the anxiety and depressive disorders. Rachel has an MSc in Social Statistics and has previously worked for the Government Statistical Service.
Aidan O'Keeffe PhD, Research Associate
Linda Wijlaars MSc, Research Associate in Statistics & PhD Student
Linda is a research associate split between PCPH and the Centre for Paediatric Epidemiology and Biostatistics at the UCL Institute for Child Health. She started as an RA in October 2013 and works on a project to determine how contact with primary care is associated with emergency use of secondary care services by children and young people. She is also writing up her PhD project in which she used THIN to study the association between early parental depression and child outcomes. Her PhD was sponsored by a scholarship from the NIHR School of Primary Care Research. She has a BSc and MSc in Biomedical Sciences (majoring in Epidemiology and Human Pathobiology) from the Radboud University Nijmegen, the Netherlands and also writes news articles for BioNews, and the occasional blog for Significance magazine.
