Dr. James P. Ewen is a Royal Academy of Engineering (RAEng) Research Fellow in the Tribology Group, Department of Mechanical Engineering, Imperial College London.
James uses supercomputers to study solid-liquid interfaces with molecular simulations. He studies complex formulations to identify links between their nanoscale behaviour and macroscale performance. His research is highly interdisciplinary in nature and is of direct relevance to industry. James has worked with many large multinational companies (Shell, SKF, Afton Chemical, Baker Hughes, Repsol, and Procter & Gamble), scientific software specialists (Scienomics, NextMol, and SCM), and other institutions (Natural History Museum and Diamond Light Source) to help to solve engineering grand challenges. He has also collaborated with researchers from academic institutions all over the world, including ETH Zürich, University of Bologna, University of Saarland, TU Delft, Russian Academy of Sciences, University of California Merced, and Pennsylvania State University. He is also a Visiting Research Fellow at Swinburne University of Technology, Australia. He is an Affiliate of the Institute of Molecular Science and Engineering (IMSE) and the Energy Futures Lab at Imperial College London as well as the Thomas Young Centre: The London Centre for Theory and Simulation of Materials. He is currently an Assistant Supervisor to five PhD students. He is a co-organiser of the Web Seminar Series on Tribology (WeSST) and the UK Fluids Network Special Interest Group in Non-Equilibrium Molecular Dynamics (NEMD-SIG).
In 2020, he was awarded a RAEng Research Fellowship for the project 'Controlling Friction through Molecular Engineering'. He was awarded the Innovation in Tribology Award by the Institute of Physics (IOP) in 2019 and the Tribology Bronze Medal in 2018 by the Institution of Mechanical Engineers (IMechE). In 2017, he received a Doctoral Prize Fellowship from the Engineering and Physical Sciences Research Council (EPSRC). In the same year, he was awarded the Margaret Fishenden Centenary Memorial Prize for the best PhD Thesis in the Department of Mechanical Engineering over the previous five-year period.
He completed his PhD in the Tribology Group at Imperial College London, under the supervision of Prof. Daniele Dini and Prof. Hugh Spikes in 2017. His iCASE PhD studentship was co-funded by Shell and the EPSRC and he spent 15-months placed in Shell technology centres around the world during his undergraduate and post-graduate studies. He graduated from the University of Bath with a Masters in Chemistry degree (First Class Hons.) in 2014.
