Principal Investigator

Ph.D. Western University, 2013

B.A. (Honours) McMaster University, 2007

Paul Szpak is an Associate Professor of Anthropology and Canada Research Chair in Archaeological Science at Trent University. As an undergraduate Paul worked at the Stable Isotope Biogeochemistry Laboratory at McMaster University and performed isotopic research on Pleistocene mammoths and marine fauna from British Columbia. Paul completed his doctoral studies in the Laboratory for Stable Isotope Science at Western University in 2013. His dissertation involved isotopic applications in the Andean region, specifically related to plant ecology, controlled studies examining fertilizers, and animal management practices. Paul held SSHRC, Killam and NSERC Banting postdoctoral fellowships in the Department of Anthropology at the University of British Columbia from 2013-2016 using isotopic analysis to investigate the palaeoecology of Arctic marine ecosystems. Paul has worked at Trent University since 2016 and became Director of the Trent Water Quality Centre in 2021.

Paul directs a diverse research program centered on stable isotope analysis, supported by several major grants from the Tri-Council, which includes a SSHRC Insight Grant to investigate agricultural intensification and animal management practices in the Andes (2019-2024), an NSERC Discovery Grant supporting research into long term variation in Arctic marine ecosystems (2020-2025), and a SSHRC Insight Development Grant to advance our understanding of the diet and mobility of the ancestors of the Wichita and Affiliated Tribes in the American Plains (2020-2022). These projects correspond to Paul’s broader research focus on applying chemical analyses to archaeological materials to better understand the interactions between humans, animals, plants, and their environments. He is involved in isotopic research all over the world, but presently focuses on two geographical areas: the Andean regions of northern Peru and Chile and the North American Arctic (Canada, Alaska, Greenland).

B.Sc. (Honours) Laurentian University, 2005

Matt’s academic journey began at Laurentian University, where he completed a B.Sc. (Honours) in Biology, specializing in Forensic Science. For his M.A at Western University, Matt performed uHPLC analysis of Adult Human teeth evaluating aspartic acid racemization as a means for determining age-at-death of an Individual. He also completed his doctoral studies at Western, carrying out for his dissertation on micro-CT (µCT) analysis and metric measurements of the first metatarsal to evaluate changes in bone density with increasing age of an ancient skeletal population from the Dakhleh Oasis, Egypt; this research aimed to be a straightforward method for diagnosing osteoporosis prevalence in ancient skeletal populations. Presently, Matt is starting his third year as a postdoctoral fellow at TEAL and his second year as a course instructor in forensics and anthropology at Trent. His current projects involve stable carbon and nitrogen isotope analyses on bone collagen, tooth dentine, and hair of human remains from Baja, Mexico; Fortress of Louisbourg, Nova Scotia; and a monastery in Gurat, France. He is also investigating the diet and mobility of modern sheep from Mongolia, using carbon, nitrogen, and strontium isotopes. As a senior member of the TEAL team, Matt has begun the task of bringing the younger generation up-to-speed on essential pop culture references: The Simpsons, The Office, action movies of the 1980s and 1990s, etc. In the inaugural edition of the Lab Olympics, he was awarded first place in the parafilm ball shot put and the microbalance accuracy events, proving to his competitors that he - just like a ghostbuster - has the tools and the talent. Recently, he got a Basset Hound/Beagle puppy named Winston. Winston has aspirations of joining the team as junior lab mascot.

Project: Sulfur isotopes in Arctic marine ecosystems.

Jen is currently in the second year of the Environment and Life Sciences Ph.D. program. Jen previously completed her B.Sc (Honours) in Anthropology and M.A. in Anthropology at Trent University. She is currently studying the variation in stable sulfur isotopes to determine if there are differences among species, across time, and among different types of environments in Arctic marine systems. Jen also hopes to refine the quality control criteria for stable sulfur isotope measurements of ancient bone collagen. During her undergraduate degree, Jen was involved in research that utilized stable carbon and nitrogen isotope analysis to examine the impacts of changing sea ice conditions on polar bear ecology in Lancaster Sound (Canadian High Arctic). For her MA thesis project, Jen performed stable carbon, nitrogen, and oxygen isotope analyses on ostrich eggshells to research the range, commodification, and local extinction of Asian ostriches from the Far Eastern Steppe. In her free time, Jen enjoys glamping (not camping) and consuming any form of comical media she can find. Jen is the reigning axe throwing champion, having defeated Eric Guiry in the finals of the 2019 competition.

Project: Palaeodiet of Arctic Canids

Brooke is currently in the first year of her M.A in Anthropology at Trent. She completed her undergraduate studies at Trent as well, completing a Bsc in archaeology with a minor in biology. Their research with TEAL will involve examining the paleodiet of canids from archaeological sites in the Canadian Arctic through analysis of stable carbon and nitrogen isotopes. The Arctic is a particular area of interest as Brooke's distaste for hot weather has influenced their love of the circumpolar North.  Outside of the lab, you can find Brooke running her custom embroidery business or playing for the Trent Women's Varsity Volleyball team. She has also claimed to be an excellent juggler but these claims have yet to be confirmed.

Project: Palaeoecology of Pinnipeds from Northern Labrador

Mariah grew up in Lethbridge, Alberta. While attending the University of Lethbridge, Mariah majored in Archaeology and Geography –  all while captaining the Women’s basketball team. It was during this time that she developed an interest in faunal analyses and the Canadian arctic and sub-arctic cultures. In pursuing these interests further, Mariah has joined TEAL for her master’s degree. Mariah will be conducting isotopic analyses on seal remains from a site in northern Labrador. In her spare time Mariah enjoys reading, painting, and making pottery. She also loves visiting small historical/archaeological sites and museums. Not one to stay sedentary, Mariah enjoys traveling – her favourite place to visit so far has been Israel, where she has been fortunate enough to have done archaeological work on three different occasions. As a huge fan of cats and a proponent of the theory that Revenge of the Sith is the best Star Wars movie (it’s clearly not), Mariah would normally be an outcast in the TEAL lab, but her experience during high-level university athletics will allow TEAL to defeat their nemesis in competition… the dastardly Connelly Lab. One more thing to know about Mariah is her love of dill. She uses this seasoning on chips, popcorn, nuts, soups, chicken, etc, and she loves the use of dill pickles on pizza.

Project: Exploring camelid wool trade networks through carbon and nitrogen isotopic analysis of archaeological textiles from the Atacama Desert, northern Chile

Tessa's interest in archaeological science began when she took a class in nutritional archaeology at the University of British Columbia. Her undergraduate thesis put these analytical techniques into practice when she used X-Ray Fluorescence on Coast Salish weavings to identify mordants (metallic compounds that bind dyes to fibers) which impact the blankets' preservation and optimal conditions for curation. This thesis is now moving toward publication. Tessa has completed the first year of the MA program at Trent University and all the course work that entails.  Moving into her second year, she is spending a lot of time in the lab, generating data and perusing her hopes and dreams in stable isotope analysis.  Tessa has been disappointed in the low abundance of carnivorous plants in Ontario and feels their purported prevalence may have been exaggerated.

Project: Diet-tissue discrimination factors for canids provisioned with a wide range of meats and cheeses.

Joy's past is shrouded in mystery but she joined the group from Istanbul, Turkey in 2017. She has a cauliflower ear and a friendly disposition. Her favourite piece of anthropological literature is "How Dogs Dream" by Eduardo Kohn, although she admits that she doesn't really understand it. Her primary research interests include the anthropology of sleeping and laziness, experimental archaeology focusing on the taphonomy of large mammal bones exposed to carnivore gnawing, and the behavioural ecology of squirrels, chipmunks, and rabbits. Her main contribution to the lab is the initial processing of animals bones that are used in methodological studies such as the VIP and DATA graduate class projects.
