Mr Nelson Grisales Alzate

PhD Student

Nelson graduated as a Biologist in the Universidad de Antioquia, Colombia, in 2009. In 2010-2011 he completed a MSc in Molecular Biology of parasites and disease vectors in the Liverpool School of Tropical Medicine and is currently enrolled in a PhD in Tropical Medicine at LSTM.

Nelson is interested in the development and testing of innovative vector control methods as well as in the optimisation of the classic ones. Currently, as part of a large-scale field trial in Burkina Faso he is evaluating the effectiveness of a new combination Long lasting insecticidal net (LLIN) as a tool to prevent and control malaria and as an alternative to manage insecticide.
