Rebekah's research is conducted in the MAGIC research group's metal-free and MC-ICP-MS laboratories. She is currently investigating the Cd stable isotope compositions of plants.
Rebekah graduated from her undergraduate degree (MSci. Geoscience) from Durham University in 2013 and later that year began her PhD at Imperial College London's Department of Earth Science and Engineering (ESE) on "the biomedical potential of high precision zinc isotope analysis". She was supervised by Prof. Mark Rehkämper (ESE) and Dr. Fiona Larner of University of Oxford.
During her PhD she focused mainly on Zn stable isotope analysis using Multiple Collector Inductively Coupled Plasma Mass Spectrometry (MC-ICP-MS), and also worked with Cu and Fe stable isotope analysis and ICP-MS trace metal concentration analysis. MC-ICP-MS enables the detection of very small differences in metal stable isotope ratios. Originally developed for geochemistry research, Rebekah used the technique to analyse human metabolism/processing of essential metals, by isolating and measuring metals from various different tissues (e.g. blood, urine, sputum, hair, muscle and other tissues). As well as using the technique to gain insight into how the body processes metals, another aim of this research field is to help medical professionals understand diseases and disorders. This understanding may lead to the development of bio-markers to help identify disorders before symptoms begin and to track disease progression.
During her postgraduate study, Rebekah was a Teaching Assistant for two ESE undergraduate courses ('Solid Earth Geochemistry' and 'Climate'). She also volunteered at summer schools: tutorial and practical demonstrations for the UNIQ summer school, University of Oxford (http://www.uniq.ox.ac.uk/) and workshop for Global Summer School, Imperial College London (https://www.imperial.ac.uk/be-inspired/global-summer-school/)
Alongside her research, Rebekah also enjoys participating in and organising science outreach events, such as Pint of Science (https://pintofscience.co.uk/team-page/), the UK Space Design Competition (http://uksdc.org/), the Imperial Festival (http://www.imperial.ac.uk/festival/) and the Imperial Fringe Festival.
