Dr Tomas Martin


My research uses advanced microstructural characterisation techniques to characterise the structure and chemistry of materials for nuclear power plants, semiconductor devices and aerospace. I use a wide variety of microscopy and spectroscopy techniques including atom probe tomography, electron microscopy, secondary ion mass spectrometry, X-ray photoemission and X-ray diffraction to investigate materials including zirconium alloys, actinides, steel, nickel superalloys, silicon, biomaterials and diamond.

I obtained an MSci in Physics with Astrophysics from the University of Bristol in 2008, and subsequently a PhD in physical chemistry, where I studied the electronic and structural properties of surface termination of diamond. My work on the lithium-oxygen termination was patented in 2012. Following my doctorate I spent two years working as a consultant engineer in the renewable energy industry, advising on the construction and operation of large-scale wind and solar power plants around the world. 

From 2013-2017 I was the lab manager of the atom probe tomography facility at the University of Oxford, where I ran the only three atom probe tomography instruments in the UK. I was responsible for training of users on the instruments and operation for external collaborations on a wide variety of projects. 

At Bristol my work revolves around studying the mechanistic behaviour of metal microstructure during corrosion and heat treatments. I am also the lead researcher in Physics for the university's High Temperature Centre, sponsored by EDF. I supervise PhD students in hot water corrosion and stress corrosion cracking in steel and zirconium, creep cavitation in steel and in nuclear forensics. I also research the isotopic signature of materials in the field of nuclear forensics at sites such as Fukushima.
