She graduated with her B.Sc. in Ethnobotany, minoring in Anthropology, from the University of Hawaii in 2010, and completed her M.Sc. in Biological Sciences at Brock University in 2016. Her M.Sc. research focused using photographic time series to quantify age-specific changes in morphology and survival in Rhizocarpon geographicum over a 4-yr period at Illecillewaet Glacier, BC. Theresa has since taken an avid interest in the field of herpetology. During her time in the field, Theresa enjoys familiarizing herself with the native flora including rare plants, lichen, and fungi of the Niagara region.

She first started working in wildlife conservation during her undergraduate degree, when she worked as a summer student with the Ministry of Natural Resources and Forestry. She graduated with a B.Sc. in Fish and Wildlife (minoring in Geographic Information Science), from Michigan State University (MSU). After assisting with dendrochronology research at MSU and working with the Wildlife Disease Lab with the Michigan Department of Natural Resources, Brie-Anne went on to acquire her M.Sc. in 2019 in Environmental Life Science, researching amphibian environmental DNA at Trent University. 

Wynne Reichheld, Matthew Jung



Wynne (left) and Matthew (right) are both undergraduate students at Brock University, working on their own research projects in the lab of Dr. Tattersall

Both currently work for 8Trees Inc. as student field technicians, as part of the 8Trees Inc. student mentorship program.

Matthew is an undergraduate student in the Biological Sciences and Environmental Sustainability program (2017) at Brock University, and has graduated with a diploma from Niagara College in the Environmental Field and Laboratory Technician program in 2017. For his undergraduate research project, he is investigating the repeatability of measuring the thermal selection of Northern red-bellied snakes under lab conditions. 

Wynne is currently an undergraduate student at Brock University studying biology and physics. She has several responsibilities in the Tattersall lab, including assisting other graduate students with their projects. Her undergraduate research project investigates insect physiology using respirometry and thermal imaging techniques. Wynne plans to continue research with species at risk and animal physiology throughout her educational career.
