Background
Dr. Margaret (Peggy) Krahn is the Program Manager for the Environmental Assessment Program of the Environmental Conservation Division. Peggy started at NWFSC in 1978. She received a Department of Commerce Silver Medal Award in 1997 for developing innovative analytical chemistry methods that were used worldwide to determine the types and levels of contamination in marine species. Peggy received her bachelors in chemistry from the University of Minnesota and her Ph.D. in organic chemistry from the University of Washington
Current Research
In collaboration with other scientists in the Environmental Assessment Program, Peggy has developed methods to analyze for environmental contaminants, fatty acid and lipid class profiles and stable isotope ratios in marine samples (e.g., sediments or tissues from marine organisms). Program scientists, in collaboration with other researchers, are carrying out research linking contaminant levels to effects such as immune system dysfunction. In addition, collaborative research is being conducted on the feeding ecology (i.e., fatty acid profiles and stable isotope ratios) of marine mammals and their prey.
