The Derbyshire Lab uses both chemical tools and biological methods to uncover novel aspects of malaria parasite biology with the ultimate aim of identifying druggable targets. Projects range from developing assays for phenotypic and target-based screens to exploring biological pathways and identifying small molecules with potential therapeutic value. Their interdisciplinary collaborative program integrates chemical biology, molecular biology and biochemistry to globally interrogate parasite biology.
