Biomedical engineer and violinist. Recently completed PhD developing music as a real-time interface for fMRI neurofeedback.

About

I recently completed my PhD at CIBIT (University of Coimbra), working at the intersection of cognitive neuroscience, neuroimaging, and music.

Learn more about me

My research focuses on using music as real-time feedback during fMRI neurofeedback experiments. As a trained violinist and orchestral musician, I bring a unique perspective to designing immersive, auditory-based brain-computer interfaces.

I have experience with real-time fMRI, sequence optimization, open science practices, data management (BIDS), and scientific software development in Python and MATLAB.
