Biography

Dr. Treena Swanston's interest in how human health issues are connected to both biological variation and cultural processes has been at the core of her research. Her past research involved the analysis of an ancient tuberculosis strain as a way of identifying contact between First Nations and European colonists in the 19th century in northwestern British Columbia. Her dissertation ,“Past human health and migration: The analysis of microbial DNA associated with human remains recovered from a glacier in Canada,” involved the amplification and analysis of Mycobacterium tuberculosis and Helicobacter pylori DNA in tissues associated with the ancient Kwäday Dän Ts’ìnchi individual (‘Long Ago Person Found’), who was discovered in a melting glacier in British Columbia, on the traditional territory of the Champagne and Aishihik First Nations.

Currently, Dr. Swanston is part of a research team identifying biological evidence of trace element uptake in bone as a way of revealing social determinants of health. By using synchrotron light at the Canadian Light Source (CLS), the team is mapping trace elements, including lead, mercury, and strontium, in archaeological bone recovered from individuals who were interred in the Royal Naval Hospital Cemetery (1793-1822) in Antigua, West Indies. The spatial mapping of trace elements within bone is a valuable method because the high specificity of this imaging technique can identify and separate the elements that were taken in during life from the elements that are present as a result of diagenesis.

Available to supervise honours or individual study students.

Teaching and Research Interests

Dr. Swanston plans to continue with biomedical research through the analysis of microbial genetic data and trace elements. Tuberculosis (TB), a disease of great antiquity, is still a complex and biocultural health issue for many individuals, especially if the cases include coinfection complications and multidrug resistance. She also plans to focus on bone copper, zinc, and iron levels connected to immune system strategies related to TB.
