Director, Nutrition in Medicine Research Group
Associate Professor Anitra Carr's research speciality is the role of vitamin C in human health and disease. Associate Professor Carr has a background in biochemistry and biomedical research and now carries out translational ‘bench-to-bedside’ studies. She is currently running both observational and interventional studies investigating the bioavailability and health effects of vitamin C. She is particularly interested in the role of vitamin C in the prevention and treatment of acute and chronic diseases such as cancer and severe infection.
Associate Professor Carr obtained a PhD from the Department of Pathology, University of Otago, Christchurch, followed by an American Heart Association Post-doctoral Fellowship which was carried out at the Linus Pauling Institute, Oregon State University, USA. Whilst there she produced a number of high impact publications on the role of vitamin C in human health and disease; two of these supported the most recent increase of the US recommended dietary intakes for vitamin C by the US Food and Nutrition Board of the Institutes of Medicine.
Associate Professor Carr returned to the University of Otago, Christchurch, and was awarded a Sir Charles Hercus Health Research Fellowship from the Health Research Council of New Zealand to undertake research into the role of vitamin C in severe infection, particularly pneumonia and sepsis. She has also investigated the effects of intravenous vitamin C on cancer and chemotherapy-related symptoms and quality of life. Associate Professor Carr hopes to not only elucidate the underlying mechanisms of action of vitamin C, but to also improve the outcomes of patients with these conditions.
