2011-2016: PhD, Durham University. PhD student at the School of Biological and Biomedical Sciences under the supervision of Prof Nigel Robinson and Dr Ehmke Pohl. My PhD work focussed on dissecting how levels of transition metals are selectively balanced and managed by regulatory proteins within a bacterial system. I investigated factors determining selective responses of DNA-binding metal-sensors, including analysis of the formaldehyde sensor FrmR. Training in protein characterisation including UV-Visible/fluorescence spectroscopy, metalloprotein-chelator competition experiments, DNA-binding assays, and gel-filtration chromatography.

2015-2016: Research Technician, Durham University. The project aimed to assist in the analysis of metal contents of biological samples by inductively coupled plasma mass spectrometry (ICP-MS) in a collaborative project entitled: ”Unravelling and engineering the role of trace metals on recombinant therapeutic protein synthesis and heterogeneity from Chinese hamster ovary cells” in collaboration with the University of Kent and Lonza. Develop new skills in ICP-MS analysis on biological samples.

2016-present, Research Associate, Newcastle University. I am currently working in Dr Jon Marles-Wright’s group. The BBSRC project will investigate how the structure of encapsulated ferritin enzymes relates to their function within the encapsulin iron-megastores. Develop new skills in characterisation of protein structure (X-ray crystallography, EM, MS).
