Research ProfessorJohn Pickering

BSc(Hons) PhD BA(Hons)


Ahorangi Rangahau (Research Professor) John Pickering joined the Department of Medicine in 2007, initially to study how to better diagnose and treat kidney failure in the intensive care.  Now, he is a kaipūtaiao (scientist) and kaitātara koiora (biostatistician) with the Rangahau Manawa o Ōtautahi (Christchurch Heart Institute) research group of University of Ōtago Christchurch, and the Emergency medicine research group of Christchurch Hospital. His interests include optimising the use of biomarkers for diagnosis, clinical pathway development and translational research in acute care. His special interest are accelerated diagnostic pathways and troponin for possible acute myocardia infarction.

He comes from a physics background and was once part of the team that pioneered the use of lasers to remove birthmarks. In his spare time he engages in citizen science and outreach in astronomy.
