Biography

Alessandro Sbrizzi is an associate professor at the Computational Imaging group of the UMC Utrecht. He graduated in Mathematics at the Utrecht University and obtained his PhD in 2013 with a thesis focused on modelling and numerical optimization of MRI acquisition & reconstruction processes.

His research focuses on fast multi-parametric MRI (in particular MR-STAT), real-time motion-estimation (MR-MOTUS technique), radiofrequency pulse design and the application of machine learning in MRI. As a Principal investigator, he is a recipient of a NWO-VENI grant (2016-2021), a NWO-Demonstrator grant (2018-2020) and a NWO-HTSM grant (2020-2024).
