Overview
I am an electron microscopist with a focus on the characterisation of nanomaterials and heterogeneous catalysts. I use aberration-corrected scanning transmission electron microscopy to determine the atomic structure of a wide range of materials systems. Characterising the structure of materials down to the atomic scale allows a much greater understanding of their properties. I am particularly interested in determining the surface structure of materials to understand catalytic properties.
I have a particular interest in the three-dimensional imaging of nanomaterials, determining the 3D structure and elemental distribution within nanoparticles. I also have interests in imaging heterogeneous catalysts during reactions in-situ, and in combining different characterisation techniques with electron microscopy to better understand material properties.

Research
My main research focus is the development and use of electron microscopy to characterise and understand catalytic materials. In my group, we primarily use aberration-corrected scanning transmission electron microscopy to determine the atomic structure of nanoparticle catalysts. Electron microscopy has seen significant advancements over the past decade and is now an underpinning technique to understand the atomic structure of many material systems. I am particularly interested in the following specific topics in electron microscopy.
3D imaging of nanomaterials
The group develops techniques for the three-dimensional imaging of nanomaterials using electron microscopy. We make use of electron tomography to quantify the size, shape and distribution of nanoparticle catalysts and have active projects to push electron tomography to atomic resolution, enabling us to reveal the location of all atoms in a nanoparticle in 3D. We have a lot of experience in spectroscopic electron tomography, in particular in the use of energy dispersive X-ray spectroscopy to map the 3D distribution of elements within nanoparticles.
We are also pursuing the use of novel techniques to understand the 3D structure of nanoparticles. Our research includes the use of single particle reconstruction, a technique mainly used for imaging proteins and viruses, and atom counting from single atomic resolution images.

Multiscale correlative tomography: an investigation of creep cavitation in 316 stainless steel - https://doi.org/10.1038/s41598-017-06976-5
Studying reactions in-situ
The group has a particular interest in the use of in-situ systems to enable imaging of heterogeneous catalysts under reaction conditions. In-situ holders for the transmission electron microscope enable imaging of reactions at atmospheric gas pressures and elevated temperatures (over 1000 °C). Use of the systems enables our group to study a variety of catalysts in-situ to understand how they change in terms of size, shape and elemental composition, all of which have a profound effect on their catalytic properties.

Advances in image processing for electron microscopy
In support of the two major strands of my research, I have a keen interest in the development of image processing methodology and its application in electron microscopy. My group have been involved in the development and application of methodology for image segmentation, noise reduction and three-dimensional imaging. I have made contributions (sometimes minor) to widely-used software packages for electron microscopy analysis such as Hyperspy, in addition to developing my own package for segmenting electron microscopy images called ParticleSpy.
