The application of X-ray fluorescence microscopy and micro-XANES spectroscopy to study neuro-metallomics.

This early career research highlight provides a review of my own research program over the last decade, a time frame that encompasses my transition from postdoctoral fellowships to independent researcher. As an analytical chemist and applied spectroscopist, the central theme of my research program over this time has been protocol development at synchrotron facilities, with the main objective to investigate brain metal homeostasis during both brain health and brain disease. I will begin my review with an overview of brain metal homeostasis, before introducing analytical challenges associated with its study. I will then provide a brief summary of the two main X-ray techniques I have used to study brain metal homeostasis, X-ray fluorescence microscopy (XFM) and X-ray absorption near edge structure spectroscopy (XANES). The review then finishes with a summary of my main research contributions using these two techniques, put in the context of the results from others in the field.
