Maths in the Earth’s crust

This year the ERC reached a special round-number milestone: its 10,000th grantee. The successful applicant to reach this significant threshold was Inga Berre, an applied mathematician and leading Norwegian researcher in geothermal energy. We interviewed Berre to find out how mathematics is helping us understand more about this ancient energy source first used by the Romans in their spas, and what role geothermal energy can play in the transition to a carbon-neutral future.
