Dr. Zoë Vestrum: Geophysicist on Magnetotellurics & Geothermal Energy in Canada
Take a break, we’re on Smoko. In this episode, we sit down with Dr. Zoë Vestrum, a geophysicist whose research is transforming how we understand subsurface structures and renewable energy in Canada. Specializing in Magnetotellurics (MT) and geothermal energy, Zoë shares her inspiring path into geoscience, beginning with the influence of her father, a fellow geophysicist.
Zoë breaks down the science behind MT—explaining how measuring magnetic and electric fields can reveal the resistivity structure of the Earth’s crust. Her expertise supports geothermal energy exploration, with a focus on unlocking new energy solutions for remote communities across Canada.
“I thought I wanted to be a mathematician, but geology showed me a different kind of magic.” – Dr. Zoë Vestrum
We dive into her recent fieldwork in Resolute Bay, Nunavut, where Zoë and her team are exploring the potential of geothermal power for off-grid communities. Her work in the Western Canadian Sedimentary Basin and northern territories highlights how geoscience can drive sustainable energy solutions and climate resilience.
Beyond the science, Zoë also speaks to her role on the Equity, Diversity, and Inclusion (EDI) committee at the University of Alberta’s physics department. She reflects on the value of climate surveys and how data can be used to build a more inclusive academic culture—particularly in male-dominated STEM fields.
