Dorota is a Faraday Institution Post Doctoral Research Associate based at I14 beamline. She joined in 2020 after completing her PhD at the University of Manchester, School of Materials where she worked on the development and application of X-ray chemical imaging methods to study operando catalytic materials for methane upgrade processes. In her current role, she employs X-ray chemical imaging techniques to study Li-ion cathode materials designed within the Faraday Institution CATMAT project. She is also working on the development of in situ cells to study battery materials under operating conditions suitable for nano X-ray imaging.
Gea was a senior support scientist at I14, in a combined position between the Diamond Light Source and Johnson Matthey. She worked on in situ Transmission Electron Microscopy, as well as on the development of in situ sample environments for use on the hard X-ray nanoprobe.
Gea is originally from The Netherlands, where she obtained a BSc and MSc at in Molecular Life Sciences, a study programme focussed on multidisciplinary scientific research, at Wageningen University. She then did a PhD at the University of Cambridge, in the Department of Chemistry, working on structural colour in biological systems. She is a microscopist, working across various different techniques and scientific fields. After leaving Diamond she went to work for the Central Laser Facility, to work as an electron microscopist on cryo-CLEM.
Paul Quinn is the former Imaging and Microscopy Science Group Leader, and former Principal Beamline Scientist for I14. Paul joined Diamond in 2006 after working at the University of Warwick.
Research interests
X-ray microscopy, instrumentation and method development, studies of trace metals in biological samples.
Hard x-ray nanoprobes are currently being built around the world to provide high spatial resolution x-ray microscopy. These tools will allow us to probe structural and chemical variations in a wide range of samples with a 50 nm or smaller probe. This is an emerging field and a new tool for the science community and our aim is to deliver instrumentation, sample preparation and data analysis tools which open this tool to the broadest community and best scientific problems.
Using I18, the microfocus spectroscopy beamline, we've studied the affect of metal nanoparticule debris from metal on metal hips on tissue surrounding the hip. We identfied metal species in the tissue and they are co-located with particular cell types but we didn't have the spatial resolution to clearly resolve how individual cells take up the metal. I14 will be able to address this issue by providing a high resolution probe (50nm) capable of probing a range of materials in fine detail.
I am also interested in algorithm development for fast XRF data processing and XRF tomography.
