From June 1971 to September 1971, Heaney worked as a collector for the Delaware Museum of Natural History. From June 1972 to June 1975 he was a curator and research associate at the University of Minnesota. From June 1973 to August 1975 he was field and research assistant at the Smithsonian Institution. In June 1975, Heaney earned his Bachelor of Science degree from the University of Minnesota. From August 1975 to May 1979 he was curatorial assistant, teaching and research assistant at the University of Kansas. In May 1978, he was awarded a Master of Arts degree from the University of Kansas and, in October 1979, his Ph.D. From September 1979 to August 1986, he was assistant professor at the department of biology and assistant curator at the department of mammals at the Museum of Zoology, University of Michigan. From 1986 to 1988 he was a research fellow and since 1988 he has been a research associate at the Smithsonian Institution. Since 1991 he has been a research assistant at the American Museum of Natural History. From 1988 he was curator and since 2002 he has been head of the mammalogical department of the Field Museum of Natural History in Chicago, Illinois.

In 2008, Heaney and his colleague Danilo S. Balete rediscovered the Blacktail Luzon Tree Rat (Pulomys melanurus) on the Pulag on Luzon, a rodent that had been considered lost for 112 years.^[1]

Mammals described by Heaney include, among others, the Tawi-Tawi forest rat (Rattus tawitawiensis), the Palawan Montane squirrel (Sundasciurus rabori), the Dinagat bushy-tailed cloud rat (Crateromys australis), the Dinagat Gymnure (Podogymnura aureospinula) and nine species of Apomys: Apomys aurorae, Apomys banahao, Apomys brownorum, Apomys iridensis, Apomys magnus, Apomys minganensis, Apomys camiguinensis, Apomys lubangensis and Apomys sierrae.

In 1996, Pedro C. Gonzales and Robert S. Kennedy named the Panay Bark Rat (Crateromys heaneyi) in his honor.^[2] In 1997, Colin Groves honored Heaney in naming the subspecies Prionailurus bengalensis heaneyi, the Bengal cat from the Philippine island of Palawan.^[3]
