Rowan Eveline Muir

Rowan Eveline Muir

Rowan undertook an MSc by Research within VOILAb looking at the leading edge vortex as seen in bird and insect flight. In part because it’s fascinating, but also as a potential bio-inspired design optimisation for lift generation in low Reynolds aerodynamics. Since graduated, Rowan has worked in the wind industry, first at Senvion and soon after was appointed successively as WTG Package Manager of the Moray West Wind Farm at Ocean Winds.
