Research interests are in 1) bacterial disease of humans and animals, such as leishmaniases, intestinal spirochaetoses, sexually transmitted diseases, sepsis, etc. 2) drug discovery for novel antimicrobials using synthetic chemistry, AI-directed library screening, 3) antimicrobial testing and AMR, 4) vaccine development, including recombinant proteins, chimera antigens, synthetic peptides, DNA/mRNA, reverse vaccinology 5) adjuvants, 6) diagnostic assay development, especially low cost rapid point-of-care lateral flow tests, 7) immunology of vaccine responses, 8) host cell-pathogen interactions, 9) in silico computational modelling of antimicrobials and vaccine antigens.
