    Dr. Todd came to Mount Sinai as Assistant Professor in 1992. He is also an Adjunct Assistant Professor at the Johns Hopkins University, School of Hygiene and Public Health, where he is presently collaborating on three studies with Drs. B.S. Schwartz, J. Links and W.F. Stewart. He was formerly a Visiting Professor at The University of Maryland (Baltimore), Program in Toxicology, where he worked with Drs. B.A. Fowler, F.E. McNeill and E.K. Silbergeld. Dr. Todd trained at the University of Birmingham, UK, under the supervision of Dr. D.R. Chettle, who is now at McMaster University in Canada. Dr. Todd's Ph.D. thesis title was "The In Vivo measurement of Lead and Platinum in the Kidney" (1989). Principal Investigator of two R01s and co-investigator of several others, Dr. Todd is analyzing data from several hundred human bone lead measurements performed in this laboratory in connection with these studies. His current scientific work covers all aspects of in vivo bone measurements in both national and international arenas. A member of the Institute of Physics, the Institute of Physics and Engineering in Medicine and the American Association of Physicists in Medicine, Dr. Todd has also reviewed for Environmental Research, American Public Health Association, Medical Physics, Journal of the American Medical Association, Environmental Health Perspectives and is a Contributing Editor to the American Journal of Industrial Medicine.

    X-Ray Fluorescence Bone Lead Testing Facility


Bone Lead Measurements

Dr. Todd directs the Bone Lead X-Ray Fluorescence Laboratory (in the Department of Community and Preventive Medicine at The Mount Sinai Medical Center in New York City) which is one of the country's leading centers for a novel, relatively new technique for measuring long-term lead exposure. Currently, we measure people who are volunteer subjects for over a dozen federally funded research studies. We also measure many people who are referred to us by physicians and by lawyers because they have symptoms of lead toxicity or are concerned about lead exposure they may have suffered in the past. The information obtained from bone lead measurements can provide evidence of historical lead exposure, in the absence of documented exposure.

Industry Relationships

Physicians and scientists on the faculty of the Icahn School of Medicine at Mount Sinai often interact with pharmaceutical, device and biotechnology companies to improve patient care, develop new therapies and achieve scientific breakthroughs. In order to promote an ethical and transparent environment for conducting research, providing clinical care and teaching, Mount Sinai requires that salaried faculty inform the School of their relationships with such companies.

Dr. Todd did not report having any of the following types of financial relationships with industry during 2013 and/or 2014: consulting, scientific advisory board, industry-sponsored lectures, service on Board of Directors, participation on industry-sponsored committees, equity ownership valued at greater than 5% of a publicly traded company or any value in a privately held company. Please note that this information may differ from information posted on corporate sites due to timing or classification differences.

Mount Sinai's faculty policies relating to faculty collaboration with industry are posted on our website at Patients may wish to ask their physician about the activities they perform for companies.
