Research Scientists

D.J. (Dave) Sauchyn, P.Geo

Dr. Dave Sauchyn is Research Professor at the Prairie Adaptation Research Collaborative (PARC) and Director of the University of Regina Tree-Ring Lab. His main research interests are the climate and hydrology of the past millennium in Canada’s western interior and how knowledge of the past can inform scenarios of future climate and water supplies. Dave recently was Co-Director of the VACEA project: Vulnerability and Adaptation to Climate Extremes in the Americas (Argentina, Chile, Brazil, Colombia and the Canadian plains). He was senior editor of The New Normal: The Canadian Plains in a Changing Climate. Dave has given more than 350 invited talks on climate change and has been an invited expert witness in the Canadian Senate and House of Commons, and at forums hosted by provincial premiers and environment ministers.

Jeannine-Marie St. Jacques
Dr. Jeannine-Marie St. Jacques is a research associate at PARC. . Her research interests are the climatology and hydrology of the Canadian western interior, spanning deglaciation to contemporaneous and future responses to anthropogenic global warming, concentrating on the North American Great Plains drought record for the recent Holocene; the paleo-record of fire in the boreal forest; and the verification and improvement of statistical methods used in paleoclimate reconstructions.

Education: B.Sc. in Mathematics (California Institute of Technology), M.A. in Mathematics (Berkeley), B.Sc. in Biology (Toronto), M.Sc. in Botany (Toronto), Ph. D. in Biology (Queen's)

Current Students and Research Assistants

Iuliia (Yuliya) Andreichuk

Yuliya graduated from Ivano-Frankivsk National Technical University of Oil and Gas, Ukraine with a bachelor degree in Environmental Engineering and is currently a Master student in the Department of Engineering and Applied Science at the University of Regina. She has been a research assistant at PARC since February of 2015. In her research Yuliya uses regional climate models data to project changes in the streamflow for various watersheds in Alberta and Saskatchewan.

Sheena Hatcher

Sheena will graduate from the University of Regina, with a B.Sc. (hons) Psychology in 2018.  Her current research in psychology focuses on the effect of exercise on risk factors for anxiety disorders. She has a scientific background focused in biochemistery and psychology research, which can be applied to research in our lab. Sheena started working at the tree-ring lab as a student research assistant in the summer of 2017.

Samantha Kerr

Samantha graduated from the University of Regina, with a M.Sc. in Geography in 2013.  Her research focused on the effect of climate change on water resources, and  specifically the changes in occurrence of drought and flooding, in southern Saskatchewan, using dendroclimatic (tree-ring), climate model, and historical hydrometric data.  Samantha is currently a Ph.D. Student at the University of Regina in the Department of Geography and Environmental Studies. She is also a Research Assistant in the Dendro Lab.

Eva Lopez

Eva graduated from Towson University with a B.Sc. in Environmental Biology and a minor in Chemistry. She is now a M.Sc. candidate supervised by Dr. Mark Vanderwel and Dr. Dave Sauchyn. She is currently investigating the connections trees have with the climate; particularly focusing on how climate change will influence growth rates through dendrochronology and forestry. Her sites range through the cypress hills in Saskatchewan and Alberta.  Eva is attempting to understand how increased atmospheric carbon dioxide concentration and increased aridity has and will impact tree physiological processes.
