Prior to joining Sciences, Dr. Gibb served as the Senior Science Advisor at the National Center for Environmental Assessment of the U.S. Environmental Protection Agency. Dr. Gibb has over 25 years of experience in health and environmental sciences and also held positions as the Associate Director for Health and Assistant Center Director at the National Center for Environmental Assessment. As the Associate Director for Health, Dr. Gibb was responsible for EPA’s Integrated Risk Information System (IRIS), an on-line system of EPA’s risk assessments. Dr. Gibb was the Project Officer for EPA’s cooperative agreements with the World Health Organization. He was the lead author for the Office of Research and Development’s multiyear research plan for mercury. Dr. Gibb is a recognized international expert on the health effects of metals and in particular arsenic, chromium, nickel, and copper. Dr. Gibb was the recipient of the EPA’s Scientific and Technological Achievement Award for his study of lung cancer mortality and clinical irritation among chromate production workers. He was also the recipient of the EPA’s Gold Medal for Exceptional Service for his work on the drinking water standard for arsenic.

Timothy J. Ledbetter - Ethics Representative

LEDBETTER, Timothy J., DMin, BCC  

Ethics Representative

10/1/2013 - 9/30/2016

I am honored to be invited to offer support from the perspective of ethical considerations to the good work of the USTUR Advisory Committee. This appointment follows the conclusion of a most enjoyable term serving on the Central Department of Energy Institutional Review Board (CDOEIRB) as a non-scientific community member. In addition, I have been privileged to assist the Battelle-PNNL IRB in a similar capacity over the past 16 years. I have found congruency of concerns and discernment processes between research ethics and clinical ethics. In my capacity as member and co-chair of biomedical and hospice ethics committees, I have come to appreciate the vital and critical importance of clear and consistent ethical deliberation practices. Toward this end, I have extensively utilized what I believe is the seminal work on clinical ethics, Clinical Ethics 7th ed., by AR Jonsen, M Siegler & WJ Winslade (2010, McGraw-Hill). (Albert R. Jonsen is a godfather of the modern ethics movement and co-author of the Belmont Report which established primary ethical principles.) Several years ago, the PNNL IRB manager at that time and I developed and utilized a human subjects protection discernment protocol based on this text. Finally, in my vocation as hospital and hospice chaplain, I have learned the importance of finding ways to help survivors and future generations benefit from knowledge gained from the past and present. My desire is to appreciate and further the mission and values of the USTUR and assist wherever I can to its unique contributions to the health of our communities and world.
