Research

M.Sc. by Research and Ph.D. projects are available in the group.

I work in materials physics and lead the Surface, Interface & Thin Film Group at Warwick. The focus of my research is the growth by molecular beam epitaxy (MBE) of novel materials, applying the techniques of surface science to understand epitaxial crystal growth. These material systems include topological semimetal / semiconductor heterostructures and advanced photocathode materials for operation in both inert gas atmosphere and vacuum. As well as exploring the growth of such materials, I characterise their fundamental properties using a variety of techniques (e.g. photoemission, diffraction) and collaborate with other research groups and companies to apply them in advanced technologies (e.g. spintronic devices, sensors, quantum communications). I have an interest in applying theoretical technqiues such as density functional theory (DFT) and kinetic Monte Carlo simulation to understand the properties and growth of materials and nano-structures. I work in several multi-group and external collaborations, and use a variety of central facilities such as synchrotron radiation sources. With Dr. Yorck Ramachers, I am developing ultra-violet light detectors, combining thin-film growth and surface science with electron multiplier technology originally developed at CERN.

Teaching and other activities

I lecture Condensed Matter Physics in the final year of the MPhys and lead the first year Electronics Workshop. The latter includes remote learning activities originally developed during the COVID pandemic. I previously redeveloped and taught the core second year course on Quantum Mechanics and lectured in Geophysics. I supervise experiment-based final year undergraduate projects and contribute to skills development work, mentoring both MPhys Group Projects and second year Presentation Skills projects. On the postgraduate side, I am a former Admissions Tutor and MPAGS Academic Coordinator, and I run MPAGS modules in Nano/Surface Science and Hands-on Vacuum Science. I am the first member of staff in Physics to become a Fellow of the Warwick International Higher Education Academy and a Senior Fellow of the Higher Education Academy (Advance HE). I was a member of the University's Gender Task Force and the Department's Welfare & Communication group. I developed the interdisciplinary Science of Music module with Warwick's Institute for Advanced Teaching and Learning IATL as part of an Academic Fellowship called Science, Maths and Music. A Warwick-Monash Masterclass video is available about this course. I am a member of IATL's Management and Education Committee, and am involved in developing interdisciplinarity across the university.

I am a member of the Institute of PhysicsLink opens in a new window (IoP) and Fellow of the Royal Microscopical Society. I review research proposals for EPSRC, the Royal Society, Agence Nationale de Recherche, the National Epitaxy Facility, and Warwick schemes (e.g. IAS and URSS). I review article submissions for many journals such as Physical Review, Vacuum and Journal of Physics: Condensed Matter and was awarded a Certificate of Outstanding Contribution in Reviewing by Applied Surface Science. My full journal review record can be found on Publons. I am a former Editor of Solid State Communications.

I am involved in the organisation of numerous scientific meetings, conferences and international collaborations. For example, I co-developed the international conference series SemiconNano and co-organised symposia on Epitaxial integration of dissimilar materials: challenges and fundamentals at EMRS, Spring 2018, and Innovative and advanced epitaxy at EMRS, Fall 2022. I am a programme committee member for Euro-MBE and lead the work group on fundamental research and new materials of the EU COST action OPERA which runs until autumn 2025.
