Hi all, Dr. Mike is here.
I would like to let you know my Vitamin D experience.
After completing my Ph.D. and M.D. degrees, I joined the Endocrine Section at Massachusetts General Hospital (MGH) and set up a laboratory while I was finishing my fourth year of medical school. After completing medical school, I did my internship and residency at MGH, and, at the same time, established a vitamin D laboratory at MGH and initiated my award-winning research on the photobiology of vitamin D. Over the next decade I served as Associate Professor of Medicine Harvard Medical School, Associate Professor of Nutritional Biochemistry, Massachusetts Institute of Technology, Associate Director Clinical Research Center, Massachusetts Institute of Technology, Cambridge MA, Director, Vitamin D and Bone Metabolism Laboratory USDA/Human Nutrition Research Center on Aging at Tufts University, Professor of Physiology, Physiology Department, Tufts University Medical School, Professor Medicine,Tufts University Medical School, Professor of Nutrition Tufts University and I made a number of important observations in the vitamin D field. I defined the mechanism of vitamin D production in the skin. I showed the impact of latitude, time of day, season, sunscreen use and altitude on sunlight-induced, cutaneous vitamin D. For example, I reported that exposure to sunlight at latitudes above Atlanta, Georgia were ineffective in producing any significant vitamin D from the months of November through February. I also found that exposure to early morning and late afternoon sunlight even in the summer resulted in no significant production of vitamin D in the skin. The only times vitamin D was produced was from 10 AM to 3 PM.
And it's not over! I'm still working on many projects and I will keep you informed about current studies & research projects.
