Louisa Messenger is an Assistant Professor at the London School of Hygiene and Tropical Medicine with more than 13 years of experience, specialising primarily in molecular entomology and parasitology of different vector-borne diseases across multiple continents. Her research interests have concentrated on two areas: the evaluation and implementation of novel, vector control interventions and the application of basic science techniques to improve disease surveillance and management strategies. She currently supports insecticide resistance monitoring activities of two randomized controlled trials (RCTs) evaluating next-generation long-lasting insecticidal nets (LLINs) for control of malaria transmitted by pyrethroid-resistant vectors in Tanzania (NCT03554616) and Benin (NCT03931473) and of a Phase III community evaluation of a novel indoor residual spraying insecticide to control malaria vector populations in Tanzania (NCT05150808). Louisa previously held an American Society for Microbiology Post-Doctoral Fellowship at the Centers for Disease Control and Prevention, Atlanta, USA (2016-2019), a L'Oreal-UNESCO Women in Science UK and Ireland Fellowship (2016) and was a project manager of a USAID-sponsored RCT in Muheza, Tanzania (NCT02533336; 2015-2016). Louisa has a PhD (2015) and MSc (2009, Distinction) from the London School of Hygiene and Tropical Medicine and a BA (2008) from the University of Cambridge.
