Dr Irina Chis Ster is a Senior Lecturer in Biostatistics.
Her current research programme focuses on hospital-acquired bacterial infections, antimicrobial therapy and the risk of emerging resistance, particularly in intensive care units.
Her scientific interests and experiences span a variety of observational epidemiological and clinical data of different complexities, including those featuring spatio-temporal components or hierarchical structure. The latter may arise from patients’ longitudinal observations, individuals within a spatial, administrative or household unit, multiple hospital episodes or clustered survey design. Her past work involved developing computationally intensive methodologies for statistical inference and missing data in both Bayesian and classical frequentist context.
Dr Irina Chis Ster joined St George’s in June 2013 as tenure track after holding research positions in biostatistics with Imperial College London and University College London.
She holds a PhD in Mathematics and an MSc in Medical Statistics (London School of Hygiene and Tropical Medicine).
She provides statistical consultancy for studies conducted by scientists and clinicians across St George's, University of London and St George's Hospital.
