My research is mainly focused on the development and application of two promising label-free imaging techniques, Matrix Assisted Laser Desorption Ionization (MALDI) and Secondary Ion Mass Spectrometry (SIMS) to image, map and detect neuropeptides, lipids and metal ions specifically zinc species in the brain. This is of interest for investigating the underlying chemical mechanisms and changes in biomolecules during the progression of neurological disorders. Furthermore, analytical tools based on proteomics and lipidomics are being developed to facilitate investigations with high chemical sensitivity, specificity and spatial resolution to carry out the studies at the subcellular level.
