Steven Bakhtiar, Ph.D. Dr. Bakhtiar is an expert in radiochemistry, specializing in actinides. He received his Ph.D. in nuclear radiochemistry from University of Arkansas. Dr. Bakhtiar's experience ranges from laboratory operations, quality assurance, assessments, training, science education, actinide chemistry, radiological control, and waste management. He is a member of the National Health Physics Society, Waste Education Research Consortium (WERC), International Radiological Science Application, Academy of Certified Hazardous Material Management, Institute of Nuclear Materials Management, and U.S. Department of Energy (DOE) Analytical Managers. Dr. Bakhtiar has served in many capacities at the DOE including his current position as Director of the New Brunswick Laboratory, Argonne, Illinois.

Robert Jones, Ph.D., is the chief of the Inorganic and Radiation Analytical Toxicology branch at the Center for Disease Control and Prevention (CDC). Here, he in charge of planning, implantation, oversight, and completion of programs related to public health that involve non-radioactive and radioactive elements and their isotopes. These programs help enable the CDC to assess and monitor the exposure of populations to toxic and radioactive element exposures. Jones is also overseeing the development of a variety of radionuclide bioassay methods for emergency and terrorism preparedness and response. He is involved with many long-term local, national, or international public health studies, had 106 publications, and has presented more than 60 national or international invited talked or workshops. Jones is co-chair of multiple workgroups in the DHS Integrated Consortium of Laboratory Networks (ICLN). 

Susan Langhorst, Ph.D., CHP.
