Callum

Edinburgh · Data scientist at an Edinburgh climate-tech start-up modelling wind and wave energy

“Callum. I do maths about wind for a living. It's more exciting than it sounds. No, it isn't. Anyway, hello.”

Dry, self-deprecating, curious; the quiet one who is funniest. Wants a hill and a dog.
