Callum studied at the University of Calgary, Memorial University of Newfoundland, and Bryn Mawr College in Pennsylvania, where he obtained a graduate degree in archaeology and anthropology. His principal research during three decades of fieldwork was the history and archaeological evidence for maritime adaptations of people living in marginal environments.
During this time, he worked with museums, government, Indigenous groups, and industries undertaking environmental and archaeological inventories and assessments, and conducting his own field research.
Callum has parlayed his interest in maritime adaptations and exploration as a lecturer and Zodiac driver on over 100 expedition cruises worldwide.
Callum and his wife Jane make their home on Vancouver Island and spend as much time as possible travelling around the world to expand their knowledge of other cultures.
