NAME: Rosamund E. Chapman
POSITION TITLE: Research Officer
INSTITUTION AND LOCATION: University of Cape Town, Cape Town, South Africa
DEGREE: BSc Micriobiology & Biochemistry (1988); Bsc Honours Microbiology (1989); PhD Microbiology (1996)
A. Personal statement
In 2005 I joined Prof. Anna-Lise Williamson’s research team, funded by SAAVI, working on the development of HIV-1 vaccines. I was employed as a Research Officer in the Institute of Infectious Disease and Molecular Medicine (IIDMM) at the University of Cape Town (UCT), South Africa. My expertise is in bacteriology and molecular biology. I have been involved in various different projects involving the construction of vaccines. These include the use of recombinant mycobacteria (BCG), modified vaccinia Ankara (MVA), DNA and plant expression vectors. At present I am co-supervising projects on developing vaccines against Bovine Leukemia virus and East Coast Fever. The following numbers of students have graduated under my supervision: Honours (5 graduated), MSc (3 graduated, 2 currently supervising) and PhD (4 graduated, 2 currently supervising).
B. Positions and Employment
2005 to date: Research officer, Institute of Infectious Diseases and Molecular Medicine, division of Medical Virology, University of Cape Town. The development of candidate HIV-1 subtype C vaccines, East Coast Fever vaccines and Bovine Leukemia virus vaccines.
Post-doctoral scientist in the Department of Medical Microbiology, University of Cape Town. Molecular biology research into the responses of Mycobacterium tuberculosis to stress.
Post-doctoral scientist in the Department of Molecular Biology, University of Cape Town. Molecular biology research on Thiobacillus ferroxidans.
