Iris Bell, MD, PhDIris Bell

Iris Bell, MD, PhD, is a psychiatrist, Professor of Psychiatry and Psychology, and has been a researcher in areas related to complementary and alternative medicine for 30 years. She was chosen as one of the Best Doctors in the Pacific region of the US in 1996 and in the US in 1998.

Dr. Bell has served on the faculties at Harvard Medical School, University of California San Francisco, and the University of Arizona.  She graduated magna cum laude in biology from Harvard University and then received her PhD in Neuro- and Biobehavioral Sciences and MD from Stanford University. Her psychiatry internship and residency were at the University of California–San Francisco, and she is Board certified in Psychiatry with Added Qualification in Geriatric Psychiatry. She is licensed to practice conventional medicine in Arizona and California. She is also nationally certified in biofeedback, a fellow of the American College of Nutrition, and a licensed physician in homeopathy/alternative medicine in Arizona.

She has published scores of papers and book chapters on her clinical research in addition to a monograph on environmental illness. On a lighter note, she wrote the funny, touching, and inspirational Chew on Things – It Helps You Think: Words of Wisdom from a Worried Canine to celebrate her beloved soft-coated wheaten terrier Casey's life. Throughout his life, Casey himself benefited from both Western and alternative medical help in surviving a series of health crises, from eating poison mushrooms in the backyard that sprang up overnight during his puppy time, to curing autoimmune hemolytic anemia in his old age.

Her passion is to teach people who find themselves with a chronic illness and are at the start of their own difficult journey home to themselves and to better health, a learning experience for us all. She teaches, writes, and lives in Tucson, Arizona with her three dogs: Rosie, Harry, and Charlie.

She obtained her Bachelors degree in Physics from University of Bristol, UK, her Masters degree in Radiation Physics from University of London, UK and her PhD in Physiology from Imperial College, University of London.

Ann's research focuses on the physiological effects of mental and emotional stress, and she is currently exploring the efficacies of Reiki and of Biofeedback techniques in reducing the damaging effects of stress. She has published over 80 articles in peer-reviewed scientific journals and has been a member of several review panels for National Institutes of Health. With her Reiki training and extensive scientific background, Ann hopes to bridge the gap between energy healing and quantitative scientific enquiry.

  • Measurement of effects of Reiki on cardiac function, peripheral blood flow and skin conductance in rodents, humans and non-human primates.
  • Effects of Reiki on bioelectromagnetic fields in humans.
  • Effects of hemoglobin-based blood substitutes on microvascular integrity.

Current Projects

  • Use of Biofeedback to help Parkinson's patients perform tasks involving memory and fine motor control
