Researcher biography
I obtained my M.Sc. ETH in Biomedical Engineering from the Swiss Federal Institute of Technology Zurich in 2013, where I utilized concurrent magnetic field monitoring to improve image quality and temporal stability of functional magnetic resonance imaging (fMRI). I then moved to Brisbane in 2014, to pursue a PhD at the Centre for Advanced Imaging, The University of Queensland under the supervision of Prof. Markus Barth. I investigated contrast mechanisms and signal properties of fMRI focusing on ultra-high field applications. In 2019, I joined A/Prof. Jonathan Polimeni at the Martinos Center for Biomedical Engineering, Massachusetts General Hospital, where I employed ultra-high field MRI to image the blood vessels of the human brain, and better understand their contribution to the fMRI signal. I returned to Brisbane in 2020 and I am currently a Research Fellow at the School of Information Technology and Electrical Engineering, Faculty of Engineering, Architecture and Information Technology. I am devloping new contrast mechanisms for funtional MRI and I am investigating the effect of the vasculature on the fMRI signal.
