Associate Professor John Pickering joined the Department of Medicine in 2007 to study how to better diagnose kidney disease in intensive care.
More recently he has been part of the Christchurch Heart Institute. Since 2014 he has been involved in translational research in the Emergency Department. In particular as Research Director for the ED research team he has tested, developed and implemented diagnostic pathways to more quickly and safely rule-out a heart attack in people presenting to the Emergency Department with chest pain.
He comes from a physics background and was once part of the team that pioneered the use of lasers to remove birthmarks.
