Financial Director: Jen Parks, Ph.D., LEL

Jen Parks is currently an Instructor and Academic Advisor in the Earth and Environmental Sciences department at the University of Waterloo. She obtained a PhD from the University of Waterloo in 2010. Her PhD research focused on using field mapping, geochronology, geochemical, and structural methods to study the tectonic evolution of an Archean greenstone belt and test different tectonic models in the Archean. Since finishing her PhD, she has focused on teaching at the undergraduate level. Jen currently teaches labs and lectures in areas of Mineralogy, Petrology, Structural Geology and Field Mapping. She served as the Vice Chairperson of the Precambrian Division of the GAC from 2011 to 2014.

Communications Director: Courtney Onstad, B.Sc. (Hons)

Courtney Onstad completed her B.Sc. (Hons.) in Geological Sciences in 2018 (USask) and completed two undergraduate honours projects. She is currently finishing her M.Sc. on the Fisher Gold Property at the University of Saskatchewan. Courtney has started her PhD in Earth Sciences at Simon Fraser University where she is examining methods in which geoscience is communicated to various audiences and includes the development of educational resources for students, teachers, Indigenous communities, resource companies and the general public. Courtney has worked on exploration programs in the Athabasca Basin and the Meliadine gold district. While completing her M.Sc. she joined RESPEC Consulting Inc. in Saskatoon where she worked on environmental-focused projects. In 2018 Courtney initiated a formal geology outreach program at the University of Saskatchewan and mobilized over 20 undergraduate and graduate volunteers. Volunteering has always been a strong passion of Courtney’s and she has sat on many executive committees including U of S SEG Chapter, Ore Gangue Student Society, U of S Graduate Geological Society, Western Inter-University Geoscience Conference, and the Alberta Women’s Science Network.

External Engagement Director: Andrew Abraham

From a kid collecting fossils in Lyme Regis, to a geological career exploring for metals in remote regions of the world, Andy has lived, breathed, and never stopped marveling at the Earth’s dynamic processes. He brings his love and enthusiasm for every aspect of earth science, the environment, and the quest to understand our sense of place in today’s world. 

After graduating from Aston University in the UK, Andy completed his M.Sc. at the University of Regina and his Ph.D. at the University of Toronto, where he was part of the ore deposits research group. He has been a geologist for almost forty years and has provided his knowledge and expertise for over twenty to North American and international exploration and mining projects.

Experience working on multi-faceted complex cultural and ethnic challenges developed his genuine passion for diversity and inclusion. He is equally enthusiastic about educating the public and building increased recognition of the historical role of earth science in society and how it will continue to positively shape its future. 

Whilst not working on geological problems, Andy spends time with his family and is becoming recognized as an artist and writer, creating geologically inspired images and poetry.
