Having worked for a decade as a researcher after obtaining a degree in heat transfer and fluid dynamics, Jonna Tiainen wanted to learn more about motors and generators in a commercial industrial context.

That decision — and a Business Finland-funded research project that she managed studying high-temperature heat pumps — led her to Finnish power electronics group Yaskawa Environmental Energy/The Switch, which builds permanent magnet shaft generators.

Perhaps not surprisingly for someone versed in heat and cooling dynamics, Tiainen is also a firefighter with the Rutola Volunteer Fire Brigade in Lappeenranta, south-east Finland.
