Leslie Choi

Research Assistant

Leslie joined the school in February 2017, working with the Cochrane Infectious Diseases Group (CIDG) producing novel and updating existing systematic reviews that assess the impacts of vector-control interventions on malaria transmission. These have been used for the development of the first formal World Health Organization malaria vector control guidelines. Leslie has been involved with various evidence review groups at the WHO. He currently works in the Partnership for Increasing the Impact of Vector Control (PIIVeC) in collaboration with CIDG.

Leslie’s background in in entomology having completed a MSc in Medical Entomology for Disease Control at the London School of Hygiene and Tropical Medicine following a BSc (Hons) in Biology at the University of Nottingham.

For his MSc thesis, he worked at the PAMVERC site in Moshi, Tanzania, optimising a novel assay for simulating indoor residual spray (IRS) in a laboratory environment. He then re-joined the group leading on an IRS experimental hut trial.


Leslie’s research primarily involves the synthesis of evidence on vector control interventions. This includes making methodological advancements in the critical appraisal of studies assessing the effectiveness of vector control interventions. As part of PIIVeC, Leslie also produces various kinds of reviews and evidence scoping documents to guide country level policies and decisions. He also supports the PIIVeC research fellows, proving guidance on evidence review methods.
Leslie is working on a PhD on entomological data requirements for decision making. Many studies involving vector control tools measure only entomological outcomes. Using this data to make policy requires greater understanding as to whether and how entomological data can be an appropriate proxy for disease outcomes. This project will address this question.


 Leslie is also involved in teaching on TROP973 Systematic Reviews for Policy and Practice and DTMH.
