Biography

My research focus lies on multi-spectral imaging of the human retina and small rodents spinal cord for data inversion contained into spectral images to yield quantified chemical maps, hyperspectral analysis for non-invasive mapping of biomarkers; such as methaemoglobin, oxy­ and deoxy-haemoglobin, by using imaging and spectroscopy techniques for non-invasive multiplexed blood analysis. Research aimed for the creation of low-cost biomedical instrumentation and imaging applications for low resource settings and emergency situations, implementing light propagation Monte-Carlo modelling in the retina and tissues combined with analytical physical models.
