Dr. James P. Ewen is a Research Associate in the Tribology Group at Imperial College London.
He studies solid-liquid interfaces using molecular simulations. Most of his research involves identifying links between the nanoscale behaviour of lubricants and their macroscale performance. His research is highly interdisciplinary in nature and is of direct relevance to industry. As such, he has collaborated with several industrial (Shell, SKF, Afton Chemical) and academic (ETH Zürich, Swinburne University of Technology, University of Modena, University of Saarland, UC Merced) partners to help solve important engineering problems.
He graduated from the University of Bath with a Masters in Chemistry degree (First Class Hons.) in 2014. The same year, he began a PhD in the Tribology Group at Imperial College London, under the supervision of Prof. Daniele Dini and Prof. Hugh Spikes. His CASE PhD studentship was co-funded by Shell and the EPSRC and he has spent 15-month placed in Shell technology centres around the world during his undergraduate and post-graduate studies. He finished his PhD in 2017 and was awarded a 12-month Engineering and Physical Sciences Research Council) EPSRC Doctoral Prize Fellowship. He was awarded a Tribology Bronze Medal in 2018 by the IMechE and the Innovation in Tribology Award by the IOP in 2019.
