Associate Professor Ronald Geskus

Head of Biostatistics Group

At OUCRU, Dr Ronald Geskus provides direct support to PhD/DPhil students and senior researchers and increases their statistical knowledge via teaching. He trains the junior staff in the biostatistics group to become independent statisticians.

An understanding of statistical methods and their underlying assumptions is essential for high-quality quantitative research and correct interpretation of the numbers that are obtained.

Ronald Geskus: Sophisticated biostatistics for complex clinical research from NDM Oxford on Vimeo.

Dr Geskus draws his inspiration from using statistical methods to understand the mechanisms that lead to the observed data. His interest is in the application of statistics in medicine and epidemiology, especially in the field of infectious diseases. He has made contributions to i) models for complex time-to-event data (competing risks, multi-state models), ii) models for complex longitudinal data, iii) prediction based on time-updated marker values, iv) causal inference, and v) principles of data visualization.
