Protozoan parasites are the causative agents of a wide range of important human and animal diseases, including malaria. Current work in Paul's laboratory is focused on furthering the understanding of the role of lipid biosynthesis and membrane trafficking in host-pathogen interactions, with a view to elucidating protozoan specific activities amenable to therapeutic intervention. Previous to his appointment in 2004 Paul worked in research posts at Imperial College London and at the Medical Research Council's National Institute for Medical Research.

1. Protozoan sphingolipid biosynthesis (with Prof Ehmke Pohl and others)

2. Antileishmanial discovery (with Prof Patrick Steel and others)

3. Antileishmanial mode of action deconvolution (with GSK and others)
