Ryan Miller is an ecologist and senior analyst with United States Department of Agriculture Centers for Epidemiology and Animal Health. He received a Bachelor of Science in Forest Ecology and a minor in spatial information systems from Colorado State University. Working as a collaborating scientist with the United States Forest Service Rocky Mountain Research Center he completed a Master of Science. His graduate studies focused on landscape scale forest dynamics and related population dynamics of the northern goshawk. Following his graduate work he spent 5 years as a collaborating scientist with the National Cancer Institute where he participated in the development of landscape scale indices estimating pesticide exposure in human epidemiologic investigations of cancer. He is currently a PhD student in zoology with Dr. Colleen Webb in the Webb Lab at Colorado State University.
Ryan serves on several National committees, most notably the APHIS National Feral Swine Steering Committee but has also served on the National Bovine Tuberculosis and Brucellosis Regulatory Working Group, a National Institute for Mathematical and Biological Synthesis (NIMBioS) working group modeled cattle movement and transmission dynamics of bovine tuberculosis and several other committees. Ryan was a contributing author to two technical reports addressing the risk of introduction and spread of Mycobacterium bovis in Minnesota and in the United States. Ryan has also served on the National Avian Influenza Scientific Advisory Committee which developed sampling and surveillance strategies for first detection of highly pathogenic avian influenza in the United States. He also served on the National Highly Pathogenic Avian Influenza Risk Analysis Committee which developed models of wild bird movements and avian influenzas.
Ryan has participated in a broad range of ecological projects addressing the epidemiology of viruses, bacteria, and ectoparasites. Some of these projects include: assessing the risk of introduction and establishment of exotic tick species such as the tropical bont and cattle fever ticks; ecology and transmission dynamics of arboviruses such as Everglades virus; targeted surveillance for deer hair loss syndrome in the Pacific Northwest; and spatially targeted surveillance for scrapie.
His current research is focused on understanding direct and indirect contact rates between wildlife and livestock to better understand potential transmission and spread of bovine tuberculosis. He is a collaborating scientist with two projects at the APHIS National Wildlife Research Center, the project in Ecology of Emerging Viral and Bacterial Diseases in Wildlife and the project Controlling Wildlife Vectors of Bovine Tuberculosis. He has published in Epidemiology and Infection, PloS One, European Journal of Wildlife Research, Environmental Health Perspectives, Preventive Veterinary Medicine, Vector-Borne and Zoonotic Diseases, Journal of Parasites & Vectors, Epidemiology, Emerging Infectious Disease, and Journal of the American Veterinary Medical Association.
