Dr. Sandra Barr: Geoscience Educator Reflects on 45 Years of Teaching & Research
Take a break, we’re on Smoko. This week, we’re honored to welcome Dr. Sandra Barr, a professor whose passion for teaching and geology has influenced generations of students over her 45-year career in geoscience education.
With more than 4,000 students taught, Sandra reflects on the deeply rewarding experience of guiding learners as they discover their own passion for the Earth sciences. Her teaching philosophy centers on flexibility and empathy—adapting to the diverse learning styles of her students while emphasizing the lifelong value of curiosity and exploration.
"I didn’t start university thinking I’d be a geologist, but it became destiny." – Dr. Sandra Barr
Sandra shares stories from the classroom and the field, including how her students have expanded her own understanding of geology through shared experiences and open dialogue. Her approach highlights how teaching is not just about transferring knowledge—it's about building community and encouraging discovery.
In the second half of the episode, Sandra discusses her collaborative research on the geology of the Appalachians, where she works as a generalist alongside experts across disciplines. From rock sampling to reconstructing tectonic histories, her work exemplifies the intellectual curiosity that has defined her career.
We also explore how the field of geology is evolving—from increasing gender representation to shifting paradigms in research and education. Sandra’s reflections offer valuable lessons in resilience, mentorship, and the enduring excitement of studying our planet’s history.
