Biography
Daniel Walsh - Unit Leader, Montana Cooperative Wildlife Research Unit
Dr. Walsh received graduate degrees in Fisheries and Wildlife and Statistics from Michigan State University and Colorado State University. He worked as a Disease Researcher with Colorado Division of Wildlife and as a Quantitative Ecologist at the USGS National Wildlife Health Center before joining the Montana Unit in 2022. He conducts applied research that develops and applies novel quantitative approaches in conjunction with field research to improve the health of wildlife populations. His research interests are broad, and he has worked on a wide array of taxonomic groups and wildlife health issues including chronic wasting disease, bighorn sheep respiratory disease, avian influenza, white nose syndrome, New Castle disease, among others. One focus of his current research is leveraging systems modeling to inform decision-making and applying scientific principles to the implementation of management efforts to improve the likelihood of desired outcomes. Additionally, Dr. Walsh has helped develop national surveillance strategies for avian influenza and white nose syndrome and has conducted extensive work with the World Animal Health Organisation and others to build wildlife health capacity globally. Dr. Walsh will teach courses in statistical methods for population dynamics and wildlife health modeling.
