I qualified in the University of Edinburgh and trained in general medicine and infectious diseases in Edinburgh, Manchester and London before taking up the post of consultant in the regional infectious diseases unit based at the Western General Hospital in Edinburgh in 1989. I am Honorary Professor of Infectious Diseases at Edinburgh University (since 2009).

My research interests include the evaluation of antiviral drug resistance, the management of opportunistic infections and the evaluation of anti-infectives (antibiotics, anti-viral agents and anti-fungal agents). I am the lead clinician for clinical research in the regional infectious diseases unit in Edinburgh.

I was appointed to serve on the Expert Advisory Group on AIDS to advise the four Chief Medical Officers on matters relating to HIV and AIDS (2007-2011).
