Dr Brett Nixon obtained his PhD in 1999 from the University of Newcastle and the Vertebrate Biocontrol CRC. He then undertook post-doctoral research in the Department of Cell Biology, Emory University, GA, USA (1999-2000) centred on the characterisation of knockout mouse models bearing targeted deletions of key proteins involved in gamete interactions. In 2001, Brett returned to the University of Newcastle and has since established a research program focusing on the molecular basis of mammalian gamete interaction. He is particularly interested in driving applied outcomes to help improve the diagnosis and treatment of male infertility and to inform the development of novel contraceptive strategies.
