Research Interests

Population biology and control of parasitic diseases

My research aims to identify the environmental and host factors that determine parasite abundance, and to use this knowledge to inform disease control programmes.  Research focuses on two groups of important human parasites: soil-transmitted helminths, particularly hookworm, and the leishmaniases.  This involves a combination of longitudinal field studies, quantitative analysis, and laboratory studies of host genetics and immunology. 

A major research area is understanding the role of host genetics in infection.  Using quantitative genetic approaches, I am exploring the importance of host genetic factors in controlling whether people are heavily infected with helminth parasites.  This work uses data from large field studies in Brazil and Papua New Guinea, with the ultimate aim to identify genes controlling infection.  For visceral leishmaniasis, gene mapping studies are being carried out with colleagues in Barcelona and Manchester.  We are using genome-wide association analysis and fine-mapping to characterise resistance loci in domestic dogs, which are the major reservoir of human infection. 

Field studies on visceral leishmaniasis in Brazil focus on understanding the epidemiology of infection in domestic dogs, and using novel insecticide treatments (long-lasting topical deltamethrin of dogs) to control infection. This work is carried out in collaboration with the University of Warwick and the Instituto Evandro Chagas, Brazil.  In Colombia, I have been investigating the role of domestic and wild mammals as reservoir hosts in the epidemiology of a recent outbreak of cutaneous leishmaniasis, with colleagues from CIDEIM, Colombia. 

Funding for research comes from the European Union Framework 7 and the Wellcome Trust.

 

Current Projects

  1. Epidemiology, immunology and genetics of parasitic infection, particularly human hookworm infection and canine visceral leishmaniasis.
  2. Immunology and genetics of human hookworm infection in Papua New Guinea.
