Edzard Ernst (January 30, 1948 in Wiesbaden, West Germany) is an academic physician and researcher specializing in the study of complementary and alternative medicine. Ernst was appointed Professor of Complementary Medicine at the University of Exeter, the first such academic position in the world.
Ernst served as chairman of Physical Medicine and Rehabilitation (PMR) at the University of Vienna, but left this position in 1993 to set up the department of Complementary Medicine at the University of Exeter in England. He became director of complementary medicine of the Peninsula Medical School (PMS) in 2002. Ernst was the first occupant of the Laing chair in Complementary Medicine, retiring in 2011. He was born and trained in Germany, where he began his medical career at a homeopathic hospital in Munich, and since 1999 has been a British citizen.
Ernst is the editor-in-chief of two medical journals: Perfusion and Focus on Alternative and Complementary Therapies. Ernst's writing appeared in a regular column in The Guardian, where he reviewed news stories about complementary medicine from an evidence-based medicine perspective. Since his research began on alternative modalities, Ernst has been seen as "the scourge of alternative medicine" for publishing critical research that exposes methods that lack documentation of efficacy.
