Lucy T - 2016

Lucy Teece [Vice-Chair] is a PhD student at the Institute of Primary Care and Health Sciences at Keele University. Her research interests include prognostic modelling, survival analysis, and competing risks. She joined the YSS committee at the beginning of 2015.

Maria Sudell [Meetings Secretary] is a PhD student at the Department of Biostatistics, University of Liverpool. Her research interests include joint modelling of longitudinal and time-to-event data and meta-analysis. She joined the YSS committee at the beginning of 2016.


David McLernon is a Research Fellow in Medical Statistics at the Institute of Applied Health Sciences, University of Aberdeen.  His research interests include prognostic modelling and dynamic prediction with primary application to reproductive medicine.  He joined the YSS committee in 2017.


Katie Fisher is a government statistician, working at Defra on waste statistics. She has recently joined the civil service from academia, having previously completed a PhD in behavioural ecology and post-doctoral position in population ecology at the University of Leeds.

Emily Granger is a PhD student in medical statistics from the University of Manchester. Her research involves developing new diagnostics for propensity score analyses which can be used to justify that the treatment effect estimate obtained using a propensity score is unbiased. She joined the YSS committee in 2018.


Altea Lorenzo-Arribas is a socio-economic statistician at Biomathematics and Statistics Scotland (BioSS) working with the Social Economic and Geographical Sciences (SEGS) group at the James Hutton Institute and the Rowett Institute in Aberdeen.

Shikta Das, a Research Associate in Epidemiology at UCL, has expertise in statistical modelling, genetics and bioinformatics, randomised clinical trials (RCT) with specialisation in statistical consulting, research design and research project management. The main focus of her research was to develop longitudinal growth models, cohort data analysis and genetic association studies, exploring putative role of environmental prenatal, postnatal and adulthood factors associating with early growth in response to programming in utero and metabolic syndrome diseases, such as, Obesity and Cardio-Vascular Diseases. Shikta joined the YSS committee in 2018.

Maria Dunbar

Maria Dunbar is a Mathematical Modeller at Public Health England, Porton Down. She enjoys using statistical modelling in public health.
