Research Interests

At undergraduate Paddy studied chemistry at Balliol College, University of Oxford, (MChem, 2009), where he studied metal-ammonia solutions in the lab of Prof. Peter Edwards FRS.

He then spent a year teaching and demonstrating experiments in schools around south east England, before studying for his doctorate in the department of Physics & Astronomy, University College London (PhD 2015), in the lab of Prof. Neal Skipper and Dr. Chris Howard.

Subsequently he was awarded an EPSRC Doctoral Prize Fellowship to work in the Department of Chemical Engineering, University College London with Prof. Dan Brett. He is now an RCUK EPSRC Innovation Fellow working at Queen Mary, University of London since Janruary 2020.
