Dr Stephen Price, Senior Scientist

Stephen joined Finden in October 2017 after spending 4 years working as a postdoc on beamline I18 (Microfocus Spectroscopy) at Diamond Light Source.  Prior to that, he obtained his PhD in the electrochemistry department at University of Southampton, followed by a postdoctoral position. Stephen has extensive experience in laboratory and synchrotron characterisation, covering a range of techniques including electron microscopy, XAS, XRD, and tomography, under in situ and operando conditions, and the development of data analysis methods to help interpret the data.  Whilst at Diamond, he developed a micro reactor to enable a combination of all of these techniques, “multimodal chemical tomography”, to be used to characterise industrial catalysts under operating conditions.   Stephen remains involved with academic collaborations, presenting lectures nationally and internationally, and has a H-index of 11 with 20+ publications. Stephen received a Faraday Institution Industrial Research Fellowship in 2021. He will be working in collaboration with the University of Sheffield on the FutureCat project to discover, develop and deploy the next generation of cathode materials to drive the transition towards electric vehicles, applying methods including XRD-CT to the new cathodes developed by the FutureCat project.  Read more at

Dr Antony Vamvakeros, Research & Development Lead Scientist

Antony is the Research and Development Lead Scientist, working on the development of new algorithms and deep learning approaches for processing and analysis of tomography, scattering and spectroscopy data. His research focuses on advancing and applying chemical imaging techniques to study solid heterogeneous catalysts, fuel cells and batteries under operating conditions. Antony graduated with a Diploma in Chemical Engineering from the University of Patras before moving to the United Kingdom where he obtained an MSc in Chemical Process Engineering and a PhD in Chemistry from University College London. He then spent two years at the ESRF working as an industrial post-doctoral scientist at beamline ID15A developing X-ray diffraction computed tomography (XRD-CT) and nDTomo, a graphical user interface (GUI) software suite for handling chemical imaging and tomography data. Antony currently holds a prestigious 4 year Royal Society Industry Fellowship working in collaboration with the Dyson School of Design Engineering at Imperial College London to develop cutting-edge deep learning approaches to accelerate chemical imaging and tomography methods.

Dr Wilm Jones, Research Scientist

Wilm received his PhD from Cardiff University under the supervision of professor Michael Bowker in 2016. His project concerned photocatalytic hydrogen production using supported gold and gold alloy Nano-particles. After this Wilm was employed by Cardiff University as a research assistant based full time in Research complex at Harwell working on CO2 hydrogenation. This was followed by a positions as a research fellow as Aberdeen University on a project concerning photocatalytic NADH regeneration and as a research associate for UCL at RCaH on a project developing photocatalytic materials for the depollution of air. Currently Wilm is working for Finden investigating novel DeNOx catalyst.

Antonia is a first-year PhD student in chemistry at University College London, where she also obtained her bachelor’s and master’s degrees (with distinction). She has focused her interests on inorganic chemistry, materials science and catalysis; her research builds on these areas of interest, working on X-ray-based characterization techniques and data analysis for heterogeneous catalysts. Her skills include a wide range of laboratory and synchrotron characterization techniques such as diffraction, tomography, fluorescence, spectroscopy, electron microscopy, but also programming and machine learning techniques for data analysis. She is currently working on the Horizon Europe-funded STORMING project, which aims to develop a methane pyrolysis catalyst that will selectively produce carbon nanotubes, alongside CO2-free H2. She will provide the characterisation and multimodal in situ/operando imaging of these catalysts, along with the development of new machine learning techniques to analyse the large volume of data obtained.
