I joined the Department in 1996, after obtaining a BSc (Hons) in Zoology from the University of Edinburgh, a PhD from the Rockefeller University in New York, and postdoctoral training in the U.S. National Institutes of Health in Bethesda, Maryland. (Full CV)

Affiliation

• Department of Pathogen Molecular Biology
• Faculty of Infectious and Tropical Diseases

Teaching

My main teaching responsibility is the module 'Molecular Biology and Recombinant DNA Techniques' and I lecture on gut protozoa, phylogenetics and molecular epidemiology as part of several other modules. I was for 10 years the Course Director for the MSc in Molecular Biology of Infectious Diseases and a member of the course and examination committees for the MSc in Medical Parasitology. In August 2009 I took over as Taught Course Director for the Faculty of Infectious and Tropical Diseases.

Research

My main interests are in the genetic diversity and evolution of gut protozoan parasites, especially Entamoeba histolytica, the agent responsible for amoebic dysentery and amoebic liver abscesses, other species of Entamoeba, and Blastocystis, an organism of uncertain pathogenicity. I was involved in the E. histolytica genome project and presently work on comparative Entamoeba genomics, and I run the Entamoeba Homepage. The work on Blastocystis has focussed on sequencing its mitochondrial genome in an attempt to understand the function of the organelle in this anaerobic organism. Genome sequencing of Blastocystis and its relative Proteromonas is being undertaken. Genetic diversity, both within and between species, is being explored in both Entamoeba and Blastocystis.
