Kaci K. VanDalen

Kaci VanDalen is a biologist in the Ecology of Emerging Viruses and Bacterial Diseases project at the USDA APHIS Wildlife Services, National Wildlife Research Center (NWRC). She has held this position since 2004. In her work with wildlife diseases, Ms. VanDalen has assisted in pathogen surveillance studies and outbreak investigations. She has also conducted multiple laboratory studies and experimental infection investigations in BSL-3 and BSL-2 facilities. She has worked with a variety of host species from house finches to waterfowl to American alligators and a number of wildlife pathogens including Mycoplasma gallisepticum, West Nile virus, and influenza viruses.
