Michael John Hudak is an environmental researcher and author, Sierra Club activist, radio broadcaster, and public speaker  concerned with the environmental damage (and harm to free-living animals, or wildlife) that ranching inflicts on US public land (mostly in the Western states). He is an author of Western Turf Wars: The Politics of Public Lands Ranching (which focuses on grazing issues) and its companion series of web-based videos. In 1999, he founded the nonprofit Public Lands Without Livestock.Hudak’s grassroots educational outreach on “public lands grazing” addressed thousands of Sierrans (Sierra Club members) and others. His photos and written explanations clearly picture the ecological problems of continuing livestock production on public lands.
Before he focused entirely upon environmental activism and advocacy, he was a computer industry researcher. His doctorate (1986) in Advanced Technology (Computer Science) and bachelor’s degree (Mathematics) (1975) are from Binghamton University (also known as State University of New York at Binghamton), and his master’s degree (Computer Science) is from Northwestern University (1977). His doctoral and industrial research within the field of artificial neural systems included modeling associative memory and investigating properties of Restrictive Coulomb Energy Classifiers. His PhD dissertation was titled “Life in an Associate Memory: Tales Demons Tell.”
