Dr. Bryan's research focuses on the roles and impacts of toxic and nutritional trace elements in food and consumer product safety; marine animal health; and mercury metrology. She began her career at NIST as a graduate student doing her master's degree thesis on "Non-lethal monitoring of trace elements in bottlenose dolphins, Tursiops truncatus" and her Ph.D. dissertation on "Influence of selenium and mercury chemistries on the progression of cardiomyopathy in pygmy sperm whales, Kogia breviceps". She has extensive experience in method development and analysis of trace elements using ICP-MS, ICP-MS/MS, ID-CV-ICP-MS, and direct combustion AAS.
Dr. Bryan is the inorganic lead for NIST Food Safety and the Inorganic Chemical Metrology Group Quality Manager. She is active in developing methods and trace element value assignments to support the NIST Standard Reference Materials program. Additionally, she has led NIST Pacific Marine Mammal Health Assessments (PMMHA) supported by collaborations with several partners that included studying Hawaiian monk seals, Northern Pacific humpback whales, and bottlenose dolphin under human care in the research areas of trace elements, organic contaminants, metabolomics, stable isotopes, fatty acids, and sex/population genetics. Colleen has also been involved in several environmental projects including examining mercury spatial and temporal trends for the Alaska Marine Mammal Tissue Archival Program (AMMTAP), the Seabird Tissue Archival and Monitoring Project (STAMP), and southeastern U.S. bottlenose dolphin.
