Senior Statistician (Methodologist)
- NIHR Oxford BRC Research Fellow
My current post is split between the Nuffield Department of Primary Care Health Sciences (NDPCHS) and the Center for Statistics in Medicine (CSM).
At the NDPCHS my research focuses mainly on implementing statistical methodology widely used in other areas to medical research. For instance, I am currently investigating the use of quality control charts for the management of bipolar disorder patients. I am also looking at the different methods available to construct reference intervals (e.g. quantile regression, fractional polynomials, LMS method). At CSM, I am part of the methodological group investigating the impact of measurement error on the development and performance of prognostic models.
I have collaborated in a variety of medical research projects both randomised trials and observational studies (e.g. drug development, mental health, kidney transplants, intraocular pressure, diabetes, echocardiography, children neuroblastoma), and non-medical projects (e.g. archaeology, education, finance). I have been part of the NDPCHS statistics teaching group for pre-clinical courses, the Centre for Research on Eating Disorders at Oxford (CREDO), and the Social Psychiatry Group, Department of Psychiatry, University of Oxford. I am currently the Trial Statistician for the Oxford Renal (OxRen) study.
Among the statistical methodology featuring in my work are regression modelling (simple, multivariate, multilevel, quantile, polynomial), sampling theory, latent class analysis, missing data analysis, validity and reliability analysis, non-parametric inference, causal inference using propensity scores, use of electronic health records (CPRD), quality control charts.
I hold a "Candidato a Investigador Nacional" award for the period 2013-2016 from the Mexican National System of Investigators (SNI) and became a NIHR Oxford Biomedical Research Centre (BRC) Research Fellow in 2013.
