Andrew Harman carried out his PhD at the University of Cambridge studying how Herpes Simplex Virus enter cells and establishes epidermal infection. He moved to the Westmead Health Precinct in 2002 and is now a Professor of Virology and Immunology in the School of Medical Sciences at the University of Sydney and the Deputy Director of the Centre for Virus Research at the Westmead Institute for Medical Research. He has driven partnerships with over 30 clinicians making him globally unique in his privileged access to a wide range of human tissues freshly discarded from surgery, affected by a range of disease conditions. He holds two NHMRC Ideas Grants as CIA, which fund his two research groups that investigate sexual transmission of HIV and Inflammatory Bowel Disease. Importantly for this conference, he has identified new dendritic cell populations that inhabit the stratified squamous epithelium in addition to Langerhans’s cells.
