The Laboratory for Integrated Bioarchaeological Research in Health, Diet, Disease, and Migration (Bioarch-HDDM) is a world-leading facility, enabling innovative research on life in the past.
The Bioarch-HDDM facility enables comprehensive analysis of human remains in one location, using the most up-to-date technological equipping, and providing an essential interface between field and lab-based research. The portability of key equipment also permits access to collections around the world that would otherwise be inaccessible.
The Bioarcheology Analytical Suite:
The BIOARCHAEOLOGY ANALYTICAL SUITE is dedicated to cleaning curating skeletons brought from archaeological sites for research. The centrepiece of this facility is the Portable Digital X-ray and X-ray lead box that is used for radiographic analyses of human remains. It also serves as a workspace for graduate students and visiting scholars when analyzing our skeletal material or working with archives of our previous bioarchaeological work.
The Microscopy Suite
The Microscopy Suite houses 3 high-powered microscopes, including a Keyence Portable Digital microscope (with resolution up to x1000). The portable microscope can be used to examine and digitally record pathological lesions and trauma on skeletal samples from around the world. These images can then be brought back to McMaster University for analysis and integration in the digital image database and will be available for future research even if the original samples are no longer accessible.
The Isotope Sample Preparation Suite
The Isotope Sample Preparation Suite provides a secure sample prep facility to prepare human tissues for staple isotope analysis, focusing on diet and migration in past human populations. This facility can also be used for the preparation of modern human tissues for isotopic analysis.
The Brickley Bioarcheology Lab
The Brickley Bioarcheology Lab has the equipment and capacity to prepare a wide range of bone and tooth samples for further analysis, particularly histological work. Facilities include equipment for embedding bone and tooth samples in a variety of media, thin-sectioning equipment, and preparation of blocks for SEM analysis.
Current Research Projects:
Social-cultural Determinants of Community Health in the Western Roman Empire
This SSHRC-sponsored project is quantifying evidence of vitamin D deficiency in populations from different parts of the Roman Empire and explore reasons for differences identified. Our research has three linked objectives:
1. To examine the social and cultural factors that might contribute to vitamin D status.
2. To assess the vitamin D status of individuals of differing age, gender, and socio-economic groups, from a range of urban and rural sites from different regions and climates (England, Italy, France, Spain, and Portugal).
3. To consider the possible consequences of Vitamin D deficiency in different groups in the Roman social hierarchy across status and gender boundaries through an integration of paleopathological, funerary (e.g., grave goods) and conventional textual sources.
The Vagnari Bioarchaeological Project
Ongoing excavations of the Roman period cemetery at Vagnari (1st to 4th centuries AD) in southern Italy have uncovered over 100 burials of the people who lived and worked on this rural Imperial estate.
Research projects on the collection include:
- analyses of burial practices and distribution of grave goods
- skeletal and dental evidence for childhood stress
- diet and dental health
- breastfeeding, weaning, and childhood health
- trauma and markers of occupational stress
- geographic origins, genetic diversity, and migration
The Smith’s Knoll Project
Re-analysis of the bone fragments excavated from the Smith’s Knoll memorial site in Stoney Creek (Ontario) has contributed to on-going research on geographical origins and diet through analysis of stable isotopes, disease and trauma experienced by past groups, and development of techniques used for estimation of age at death. This 19th century sample from the War of 1812 has also been used to evaluate issues linked to disarticulated, fragmented and comingled human remains.
