On completing my PhD studies in the Kafatos/Christophides Lab at Imperial College, London, I relocated to the University of Geneva Medical School to join the Computational Evolutionary Genomics Group as a Postdoctoral researcher.
- Insect Innate Immunity
- Comparative Insect Genomics and Immunogenomics
- Evolution of Genes and Genomes
One of the major public health concerns of the new millennium centres on diseases transmitted to humans by blood-feeding insects. Sequencing of the Anopheles gambiae genome (Holt et al, 2002) drove an unprecedented acceleration in malaria research, particularly in the field of insect innate immunity, together with a growing appreciation of the importance of mosquito-parasite interactions. The second mosquito genome, Aedes aegypti (Nene et al, 2007), has enabled a comparative phylogenomic analysis of the insect immune repertoire among these two mosquitoes and the fruitfly Drosophila melanogaster. Analysis of immune signalling pathways and response modules revealed both conservative and rapidly evolving features associated with different functional gene categories and particular aspects of immune reactions (Waterhouse et al, 2007). These dynamics reflect in part the continuous readjustment between accommodation and rejection of pathogens and suggest how innate immunity may have evolved. The sequencing of these and other insect genomes enables informative comparative analyses with the integration of data sources, and the employment of a range of methodologies to build and test hypotheses, while focussing on innate immunity of disease vectors as a system of particular biomedical relevance.
