Her research interests lie in the realm of natural history and behavioral ecology of marine protected species and the impacts of human activities on these animals. Dagmar has more than 20 years of experience in National Environmental Policy Act (NEPA) documentation. She also has been involved in many outreach efforts to educate the public about marine mammals.

Dagmar’s graduate research focused on the association of bottlenose dolphins with the shrimp fishery in Galveston Bay, Texas (Gulf of Mexico). She has been involved in shipboard and aerial surveys for cetaceans along the Gulf of Mexico and Atlantic coastlines, as well as photo-identification surveys and live captures of dolphins. Her post-graduate employment has focused on an array of marine protected species assessments for the western North Atlantic Ocean, Caribbean, Gulf of Mexico, eastern and western North Pacific Ocean (including the U.S. West Coast, Alaska, Hawaii, Japan/Okinawa, and Guam/CNMI), and Mediterranean. Dagmar established Ziphius EcoServices in 2007 as a source for marine protected species expertise, especially as it relates to environmental compliance needs.​
