Professor Kelleher is a clinician scientist whose work has significantly advanced our understanding of interactions between HIV and the immune system. Focused on human T-cells and their manipulation by therapeutics, he’s made seminal contributions to the field including in relation to co-evolution of HIV and immune responses and development of a novel way of virus silencing when it is embedded in the host’s genes and inaccessible to the immune system and existing therapies. His outstanding profile is evidenced by research leadership roles and many invitations to speak at leading Australian and international symposia.
