Campbell spent his childhood on Eleuthera Island, Bahamas, in Rio de Janeiro, Brazil, and Grosse Pointe, Michigan. He received a BS in biology from Kalamazoo College (1971), an MS in biology from the University of Michigan (1973), and a Ph.D. from the Johns Hopkins School of Public Health (1984). He is married to Karen S. Lowell, a phytochemist; they have a daughter.

From 1974-1977 Campbell was the executive Director of the Bahamas National Trust,[1] the organization responsible for parks, reserves, and setting priorities for wildlife conservation in the Bahamian Archipelago. During his tenure as Director he established priorities for the protection of island-endemic species such as rock iguanas (Cyclura spp.) and hutias,[2] and started the process of the Bahamas becoming a signatory to the Convention on Trade in Endangered Species (CITES). His career in the Bahamas cumulated in the publication of The Ephemeral Islands, the first natural history of the archipelago to be published since the 1800s.
From 1978-1983 Campbell elucidated the etiology of gray crab disease, an amoebic pathogen that every spring kills ca. 30% of the blue crabs (Callinectes sapidus) in Chincoteague Bay, VA. His research showed that the disease is spread by cannibalism, mediated by ambient temperature and salinity.[3]
In 1974 Campbell was a botanical explorer at the Instituto Nacional de Pesquisas da Amazônia (INPA)[4] in Manaus, Brazil, from where he staged expeditions to study the ethnobotany of the Jamamaji and Paumari Native Americans.[5] Campbell joined the scientific staff of the New York Botanical Garden from 1984–1990, conducting floristic inventories throughout Brazilian Amazonia as part of the Projeto Flora Amazônica program;[6] destinations included O Deserto on the Rio Xingu (Pará),[7] the Rio Falsino (Amapá), Ilha de Maracá (Roraima), the Rio Moa and Serra Divisor (Acre). These expeditions resulted in several notable papers on allelopathy,[8] várzea floodplain forests[9][10] and anthropogenic lianaceous forests.[11] The Acre expeditions were chronicled in A Land of Ghosts, which won the Lannan Literary Award for Nonfiction.
In the late 1980s and 1990s, Campbell shifted his research to Africa, Asia and Antarctica: studying the impacts of elephants on west African forests,[12] the diversity of subtropical forests in southern China,[13] and conducting research on the pathologies of krill and marine isopods in the waters of Admiralty Bay, King George Island, one of the South Shetlands of the Antarctic Peninsula, joining the sixth Brazilian expedition to Antarctica (1988) and living at that nation's Comandante Ferraz Base.[14] This experience was chronicled in The Crystal Desert, which won the Burroughs Medal, the PEN Martha Albrand Award and the Houghton Mifflin Literary Fellowship Award.
Since 1991 Campbell has been a professor of biology, chair of environmental studies and Henry R. Luce Professor [15] in Nations and the Global Environment at Grinnell College.[16][17] From 1994-2007 he and his Grinnell students conducted studies on the historical ecology of the Yucatec, Mopan and Kekchi Maya of Belize, using quantitative methods to test the long-held hypothesis that the Maya Forest is anthropogenic,[18] even suggesting that its species composition was due to post-contact ranching.[19] In 2010 Campbell extrapolated this controversial hypothesis to Amazonia, presenting evidence that pre-Columbian Native Americans caused a large-scale extinction of botanical diversity before the Europeans arrived.[20]
Campbell is the author of four books of creative nonfiction. Two, The Crystal Desert and A Land of Ghosts, have been highly acclaimed.
