Dr Catherine Ludden PhD

Research Fellow


Catherine Ludden performed her PhD at the National University of Ireland Galway (2010-2104), which focused on the genetic diversity, transmission and evolution of antimicrobial resistant bacteria in nursing homes and hospitals. She was a Postdoctoral Fellow in Prof. Sharon Peacock's group at the Department of Medicine, University of Cambridge from 2014-2016. In April 2016, she joined the Clinical Research Department as a Sir Henry Wellcome Fellow.




Teaching the module for Practical Procedures in Clinical Microbiology to medical students, including laboratory supervision, practical demonstration, project design, laboratory report corrections and tutorials.


Catherine Ludden's research is based on a One Health approach to investigate the origin and transmission of antimicrobial-resistant E. coli in the UK. This will involve the use of whole-genome sequencing to determine the genetic relatedness of isolates and associated mobile genetic elements from different sources to define shared reservoirs. Mathematical modelling will be used to infer transmission, test hypotheses and to determine the likely impact of interventions to reduce transmission of antimicrobial-resistant E. coli.
