Stefan did his PhD in mathematical modelling of infectious diseases with Strathclyde University and Public Health England. Ever since, he has been fascinated by the complexities and challenges of pneumococcal vaccination. Despite the success of pneumococcal vaccines in substantially reducing the pneumococcal disease burden worldwide, serotype replacement has mitigated potentially larger impact.  He works with local and international collaborators to help better understand how to use existing pneumococcal vaccine more efficiently (i.e. reducing cost and maximising impact) and to help designing optimal future vaccine formulations. As of 2018, his research in this area is funded through a Sir Henry Dale Wellcome Trust Fellowship. He has also been following related interests, in particular for outbreak response (flu and ebola) and vaccine impact predictions (dengue and malaria). He currently serves on the WHO SAGE working groups on pneumococcal conjugate vaccines and on dengue vaccine.
