Research
My group's activities (The Virology Research Group) focus on understanding the epidemiology, immunology, evolution and disease burden of viral pathogens. With a long focus on the effectiveness of rotavirus vaccines, the group also studies other important viruses from genetics to public health. We aim to determine:
1. The immune responses induced by rotavirus vaccination and rotavirus natural infection;
2. The immunological basis for the reduced rotavirus vaccine effectiveness in Malawian children;
3. The host factors associated with vaccine responses;
4. The impact of rotavirus vaccine on rotavirus strains; and
5. The immunogenicity and efficacy of new rotavirus vaccines in Malawian children.
More recently, the Virology Group, in collaboration with Kamuzu University of Health Sciences (KUHeS) and MLW’s Genomic Epidemiology & Antimicrobial Resistant Microbes (GEARM) Group, established Malawi’s first in-country nucleotide sequencing capacity to help determine the origins and geneticepidemiology of SARS-CoV-2 circulating in Malawi. The Virology Group is expanding to understand other key enteric pathogens.
