Dr. Bryan's research focuses on the roles and impacts of toxic and nutritional trace elements in 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 performed trace element and metalloprotein analysis using techniques such as inductively coupled plasma mass spectrometry (ICP-MS), atomic absorption spectrophotometry (AAS), liquid chromatography ICP-MS (LC-ICP-MS), and gas chromatography ICP-MS (GC-ICP-MS).
Dr. Bryan is the lead for NIST Pacific Marine Mammal Health Assessment (PMMHA) programs which are supported by collaborations with several partners. PMMHA projects include 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. In addition to PMMHA research, Colleen has been involved in several other projects including examining mercury spatial and temporal trends for the Alaska Marine Mammal Tissue Archival Program (AMMTAP) and the Seabird Tissue Archival and Monitoring Project (STAMP). She is active in developing methods and trace element value assignments to support the Standard Reference Materials program. Colleen is also the Quality Manager for the Inorganic Chemical Metrology Group in the Chemical Sciences Division.
