Dr. Saddler is a research scientist and the Deputy Head of the Environmental Health and Ecological Sciences at IHI. He has been based at the Bagamoyo branch of the Ifakara Health Institute (IHI) for the last 2 years. His focus is on entomology and vector control interventions including evaluations of insecticides for indoor residual spraying. Dr. Saddler and his colleagues are currently working on two new projects that involve spatial repellents. One project investigates whether spatial repellents can be combined with odour baited mosquito traps to create a “push-pull” system that is more effective at reducing human-vector contact than either intervention alone. The other project will investigate the impact of spatial repellents on the dispersal rates of malaria vectors in the field. Before his time at IHI Dr Saddler obtained both his undergraduate degree in Biological Sciences and Master’s in Public Health Research at the University of Edinburgh in the UK. He earned a Doctor of Philosophy in Ecology and Evolution from Imperial College London in 2014. His thesis involved research into insecticide resistance in mosquito vectors – a subject which he maintains a keen interest.
