C. Graham Clark BSc PhD

vCard

Background

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)

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 Department of Infectious and Tropical Diseases.

Research

At present, 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, Trichomonas vaginalis, a common sexually transmitted disease, and Blastocystis, an organism of uncertain pathogenicity. I was involved in the recently completed E. histolytica genome project and also work on comparative Entamoeba genomics, and I run the Entamoeba Homepage. The work on Blastocystis is focussed on sequencing its mitochondrial genome in an attempt to understand the function of the organelle in this anaerobic organism.
