Professor Biological & Biomedical Sciences
Steve is a public health entomologist with a passion for studying some of the world's most important vector-borne diseases, including malaria, lymphatic filariasis, dengue and trachoma. He has considerable experience in medical entomology, parasitology, ecology and clinical epidemiology and solves pure and applied problems in the laboratory and field using a wide range of techniques from DNA finger-printing and mathematical modelling, to methods used by social scientists, epidemiologists and biologists. His particular interest is in the design of simple tools for malaria control and he has carried out field studies in The Gambia, Burkina Faso, China, Ethiopia, Kenya, Laos PDR, Tanzania, Thailand and Uganda over the last 30 years. He has published over 170 peer-reviewed papers, many in major international journals. He was in one of the leading group of researchers in the 1980s that demonstrated that insecticide-treated bednets protected children against malaria. Since then he has helped develop and carry out field trials of topical repellents, larval source management, combinations of long-lasting insecticidal nets and indoor residual spraying, new resistance-busting mosquito nets and house screening. He is an advocate for integrated vector management and the improvement of housing as a protection against vector-borne diseases.
