Cathal is an applied mathematician working as a postdoctoral research associate at both the School of Engineering and the School of Biological Science of the University of Edinburgh. He obtained his BSc in Mathematical Physics from University College Dublin in 2009, for which he was awarded the Conway Medal in Mathematical Physics. A passion for real-world problems led him to the University of Limerick; fully supported by a Mathematics Applications Consortium for Science and Industry (MACSI) scholarship, he was awarded an MSc in Mathematical Modelling in 2011 and a PhD in Applied Mathematics in 2014. His novel research has won international prizes in physics/applied mathematics and he shares his passion for mathematics as an award-winning scientific/public speaker. To date, Cathal has published papers on the mathematics of Guinness, coffee brewing, microfluidics, and wave energy. At the University of Edinburgh, he is using mathematics to unravel the novel engineering principles that enable seeds to fly over large distances with relative ease.
