Jackie joined LSHTM in 2007 and worked as a research assistant, subsequently converting to a PhD student under Prof Chris Drakeley in the Faculty of Infectious and Tropical Diseases.  Her work investigated the use of serological markers of malaria for evaluating transmission dynamics and involved fieldwork, laboratory work and epidemiological analysis.  Following completion of her PhD, she took a post-doctoral position at the Institute of Tropical Medicine in Antwerp, Belgium where she analysed serological data from South East Asia and South America.  She then moved to Zanzibar, Tanzania, as a post-doc for Karolinska Institutet, Sweden.  In Zanzibar, she worked both as a researcher and as a consultant for the Zanzibar Malaria Elimination Programme, working closely with the Surveillance, Monitoring and Evaluation team.  Her role included project managing all research activities, including study design, procurement, training, protocols, designing data collection tools, supervising field activities and undertaking all epidemiological analysis.  Projects included using molecular diagnostics to assess the burden of low-density malaria infections present in the islands, evaluation of mass screening and treatment using rapid diagnostic tests and investigating factors associated with being a malaria 'hotspot'.
