Rowan Eveline Muir

Rowan undertook an Master 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 in 2018, 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.

Dr Cathal Cummins

Dr Cathal Cummins

Cathal is Assistant Professor at Heriot Watt University, and former VOILAb’s Postdoctoral Research Associate. He obtained his BSc in Mathematical Physics from University College Dublin in 2009, an MSc in Mathematical Modelling in 2011 and a PhD in Applied Mathematics in 2014. He is the first author of the VOILAb’s Nature paper (2018; 562:414-418) that reveals the separated vortex ring underlying the flight of the dandelion seed. The article featured in the main press outlets of more than 30 countries, including BBC, The New York Times, and is ranked in the top 1% of all articles of a similar age in any journal for online attentions (https://edin.ac/2w8r4DN). Cummins received several prestigious awards, including the University College Dublin’s Conway Medal in Mathematical Physics. His MSc research was the front cover feature of the American Journal of Physics and was covered by BBC, MSNBC, and the Discovery Channel; whilst his PhD thesis featured as a Research Highlight by the American Institute of Physics.

Dr Nicola Speranza

Dr Nicola Speranza

Nicola undertook a Master Degree in Mechanical Engineering at the University of Rome Tor Vergata, where he completed his degree with full marks. In 2014, he joined VOILAb as a PhD student funded by International Paint AkzoNobel, the world-leading company in marine coatings. He studied the effect of coating roughness on the friction resistance of ship hulls. His work contributed to the development of the experimental and numerical methodologies currently adopted by AkzoNobel to assess the hydrodynamic performances of their products.
