Professor Belov's research on immunity in marsupials and monotremes provides new understanding of mammalian immune systems and has great potential for managing wildlife diseases. She overturned the paradigm that Australian mammals have primitive immune systems and demonstrated they have immune gene complements similar to our own. She discovered that it is low diversity in the major histocompatibility complex that allows the spread of Tasmanian devil facial tumour disease, and has identified novel antimicrobial and venom peptides of potential biomedical relevance.
