Expertise
"Decoding the brain enigma" is what currently drives me during my PhD in neurosciences. Studying the marriage between artificial intelligence and medical sciences, I am trying to create predictive models on MRI and clinical parameters for disease progression in Multiple Sclerosis; The creation of a guiding compass for the future.
