I am a molecular biologist who specialises in controlling insects that spread deadly or debilitating diseases like malaria, dengue, and zika.  After studying in Brazil, I received my training at the Liverpool School of Tropical Medicine - LSTM and in 2015 was awarded PhD in Tropical Medicine from the University of Liverpool.  After graduation, I returned to Brazil to set up and lead a research group at the Universidade Estadual da Paraíba - UEPB. Currently, my group focused on identifying genetic mutations that arise when mosquitoes develop resistance to the insecticides we use to control them. This forms part of a country-wide disease management strategy, and the results we generate are used to monitor populations for developing resistance, which directly feeds back to the ministry of health decision-makers. Recently, I re-join the Department Vector Biology at LSTM as associate researcher / Wellcome Trust fellow where now I lead a project, which addresses the impact of insecticide resistance and adaptation of Aedes aegypti mosquitoes and how this contributes to their transmission of arboviral diseases in Brazil.

Research Interest: Evolutionary Genetics of insecticide resistance, Vector-borne diseases and integrative approaches for vector control.
