Dr Tomas Martin
PhD(Bristol), MSci(Bristol)
Expertise
I am a materials physicist. I use microscopes to understand why materials fail at the nanoscale, and how to design smarter materials to survive longer in extreme environments like aircraft, nuclear fission and fusion reactors.
Current positions
Associate Professor in Materials Physics

Biography
After my PhD I spent two years in the renewable energy industry as a consultant engineer, advising financial investors on the technical viability of wind and solar energy installations. In 2013 I returned to academic research as a postdoctoral research fellow at the University of Oxford, where I managed the atom probe tomography lab, using this amazing characterisation technique to analyse the atomic-scale chemistry of many materials and applications, including aerospace engine alloys, the effects of irradiation on nuclear materials, biomaterials and wide band gap semiconductors. I was awarded the David Cockayne Junior Research Fellowship in Materials from Linacre College Oxford for my work.
In 2017 I returned to the University of Bristol as a fixed-term lecturer in Nuclear Materials and Fuel Cycle, designing several new lecture courses to support the new MSc in Nuclear Science and Engineering, and setting up my research group. In 2019 I successfully won a permanent lectureship in the Physics of Materials and Devices, and was promoted to Senior Lecturer in Materials Physics in 2021 and Associate Professor in Materials Physics in 2023. In 2022 I was awarded the Amazon Physical Science Fellowship, and in 2024 the EDF/Royal Academy of Engineering Senior Research Fellowship in Correlative Microscopy for Nuclear Power.
Research interests
I am Associate Professor in Materials Physics within the School of Physics at the University of Bristol. I am associated with the Interface Analysis Centre research group and the Cabot Institute as part of the Materials and Devices theme. My research uses advanced microstructural characterisation techniques to characterise the structure and chemistry of materials for nuclear power plants, semiconductor devices and aerospace. In addition I supervise final year undergraduate and PhD projects, and teach courses for the MSc in Nuclear Science and Engineering and at undergraduate level in Physics.
My research aims to take a holistic approach to materials characterisation that uses a combination of experimental techniques and computer modelling to understand the mechanisms behind materials behaviour. This includes characterisation techniques such as atom probe tomography, focused ion beam, scanning electron microscopy, transmission electron microscopy, X-ray tomography and photoemission spectroscopy, complemented by computational work using density functional theory, CALPHAD phase chemistry modelling and finite element modelling of stresses.
I link closely with colleagues in the Schools of Physics, Engineering, Chemistry and Earth Sciences, using my expertise in materials characterisation and modelling to aid research projects beyond my own. I have a number of PhD students in metallurgy and corrosion for nuclear fission, fusion, aerospace and renewable energy and work with many industrial partners including EDF Energy, NNL, Rolls Royce and UKAEA.

Teaching
I supervise undergraduate projects in the third and fourth year of the physics undergraduate course and MSc group and individual projects on the MSc in Nuclear Science and Engineering. I also supervise at the MSc by Research and PhD level, with a research group of 6-8 PhD students. Most of my projects are related to metallurgy and corrosion, but I also supervise students investigating the feasibility of future electricity grids for Net Zero. For the 2022-2023 and 2023-2024 academic years I was the Director of the MSc in Nuclear Science and Engineering.
