Nia Gray-Wannell
Nia graduated from the University of Edinburgh in 2011 with a Masters in Chemistry with Industrial Experience, as part of her degree Nia spent one year working in the James Hutton Institute conducting work on PLFAs using GC-C-IRMS. Nia’s masters dissertation was focused on carbon nanotube research and was entitled “Functionalisation of multi-walled carbon nanotubes with ethylenediamine”.
After graduating Nia spent time in France as part of the EU funded Leonardo Da Vinci scheme and worked in scientific communications for a pharmaceutical company before returning to the UK and a job as a reserach assistant in the XRD department at the James Hutton Institute. As part of the research assistant role Nia conducted commerical analysis using XRD and ancillory techniques. In addition, Nia worked on various method development projects, the most used being the now UKAS accredited cobalt hexammine trichloride CEC method. Nia began a PhD in July 2017 funded by the MDT and in collaboration with the James Hutton Institute, Swansea Univeristy and Durham University entitled "Surface chemistry of halloysite nanotubes."
