Ludwig "Lu" Norbert Carbyn is an internationally recognized expert on wolf biology, a research scientist emeritus at the Canadian Wildlife Service, and an adjunct professor at the University of Alberta in Edmonton, Alberta. He has studied wolf ecology and behaviour in Canada since 1970, including pioneering research into the ecological role of wolves as predators in the Canadian Rocky Mountains and great plains as well as the wolf-bison ecosystem of Wood Buffalo National Park. On a Canadian Wildlife Service assignment in Jasper National Park, he became the first human to study wild wolves from within a wolf pack using habituation, a method of gaining insights into the biology of wolves portrayed in fiction by Farley Mowat's popular book and film, Never Cry Wolf.
