Marta Varela

Research Associate



I am currently working on the development of non-invasive techniques to image the neonatal brain using diffuse optical imaging (further information).

For my PhD I developed novel techniques to measure cerebral blood flow (cerebral perfusion) in neonates using Magnetic Resonance Imaging (thesis).
