Research

I focus on the application of scientific machine learning (SciML), particularly physics-based machine learning, to nonlinear dynamics problems coming from engineering. I also have a broad range of research interests across the field of applied mathematics and computer science. I focus particularly on engineering-related applications (e.g., aeroelastic flutter) and I have a sideline in tactile robotics (joint with Nathan Lepora). Many mathematicians call me an engineer, whilst many engineers call me a mathematician — you can form your own opinions 😀. ...

Example PhD projects gives a few suggestions of topics I’m interested in. I manage a collaborative and friendly group of researchers who strive to do excellent work at the intersection of applied mathematics, engineering, and machine learning. We work within the larger Engineering Mathematics Research Group and have strong connections to other areas such as the Robotics Research Group, the Dynamics and Control Research Group, and the Computational Neuroscience Research Group. It’s a very supportive environment, with researchers going on to a wide range of opportunities including lectureships (e.g., Imperial, Exeter, Glasgow) and industrial careers (e.g., Dyson, Rolls Royce, GraphCore). ...

Collaborative work is one of the best parts of academic life and my previous collaborations have led to many different contributions and outcomes. Whether hosting visiting PhD students or Professors, or remote work on a topic of mutual interest, I’m keen to explore new collaborations. My research interests are quite varied and so there are many opportunities for collaboration. As such, if you are interested in collaborating with me, send me an email and we can discuss the possibilities. ...

Academic life can progress in many different ways. As far as I can, I aim to provide a healthy work environment for all those I interact with. As such, I follow these principles taken from https://ukrio.org/publications/code-of-practice-for-research/2-0-principles/ and I strongly encourage others to follow them. EXCELLENCE: organisations and researchers should strive for excellence when conducting research and aim to produce and disseminate work of the highest quality. This Code, its Principles and its Standards are intended to support these goals. ...
