MSc and MA Natural Sciences, University of Cambridge

PhD, University of Cambridge

Research interests

My research interests are many and varied. During my PhD in Cambridge, I focused on electron tomography of crystal defects using weak-beam dark-field microscopy and annular dark-field STEM, and the application of tomographic reconstruction techniques.

Between 2010 and 2013, I primarily working with fine-structure EELS as applied to ceramic materials and the investigation of their electrical properties, as well as exploring other TEM techniques such as lithium battery cathode materials with Dr Nik Reeves-McLaren, and barium titanate with Lizz Cedillo.

In 2014 I became involved with analysing particles from carbon replicas in steels in collaboration with PhD students working with Tata Steel. I also began to investigate HIPIMS films produced by Papken Hovsepian’s group at Sheffield Hallam University with some exciting multi-technique work to characterise a new film microstructure.

In 2015 I worked with Dr Conny Rodenburg and Maurizio Dapor on a multidisciplinary project exploring the Energy Loss Function through TEM EELS spectra of polymers PMMA and P3HT to contribute to their model for secondary electron spectroscopy in the SEM (papers in publication). I also contributed to a project with Wei-Gang Yang and Nicola Morley to characterise novel nanostructured multiferroic films.

Most recently I have revisited EELS fine structure analysis to do some work on Ce compounds for nuclear materials with Professor Neil Hyatt, and assisted Le Ma with analysis of state-of-the-art biological ceramic prosthetics.

My current role, working with Rolls-Royce, requires the analysis of the microstructure and properties of blown powder material-addition (3D printing) repairs of aeroengine blisks (a structure with integrated blades and disks), in high-strength titanium alloys and nickel-based superalloys.
