Thomas Crellen
I'm a postgraduate researcher working in the Bacterial Resistance Analysis Group in the Mahidol-Oxford Tropical Medicine Research Unit in Bangkok, Thailand. My project focusses on determining risk factors for acquisition of drug resistant bacteria among neonates in a Cambodian hospital. The main organism in both carriage and blood stream infections was Klebsiella pneumoniae, we have sequenced over 300 isolates and aim to use the whole genome data to reconstruct transmission networks within the ward.
Prior to starting at MORU I worked as a field epidemiologist for Médecins Sans Frontières in the Central African Republic and the Democratic Republic of Congo.
My PhD was at Imperial College London and the Wellcome Trust Sanger Institute, focussing on the genomics and epidemiology of Schistosoma mansoni, a neglected tropical disease.
