Angela McMellen Brannigan 

Technical Advisor,
National Invasive Species Council 

Angela McMellen Brannigan serves as Technical Advisor to the National Invasive Species Council where she has a lead role on scientific and technical invasive species issues that cut across multiple federal departments.  Current projects include working with federal agencies on the development of a National Early Detection and Rapid Response Framework for non-agricultural invasive species and enhancing coordination at ports of entry for effective response to detections of aquatic invasive species.  Angela served on the US delegation to the Intergovernmental Panel on Biodiversity and Ecosystem Services Plenary in September 2023 where the first global assessment on invasive species was adopted.  With much of her career spent at the United States Department of Agriculture Animal Plant Health Inspection Service, Angela has extensive experience on regulatory methods of preventing and controlling invasive species.  Angela worked on developing regulatory policy to limit the spread of invasive species through international agricultural trade in plants and plant products engaging with a wide variety of trading partners and industry groups in that capacity.  She has also worked on regulatory solutions to containing invasive species domestically collaborating with state departments of agriculture, domestic producers, and scientists.  Angela holds a B.A. in French and Biology from Austin College, a M.S. in Zoology from Michigan State University, and a Ph.D. in Forest Resources/Wildlife Ecology from the University of Georgia.
