Jessie Mosso

Jessie Mosso graduated from an engineering school in France and obtained a master’s degree in Physics (ESPCI Paris) and in Neuroscience (Sorbonne UniversitĂ©, Paris) in 2019. During her graduate studies, she conducted research projects on the topic of dissolution dynamic nuclear polarization (d-DNP) at UC San Francisco and École Normale SupĂ©rieure, Paris.

Jessie joined EPFL in September 2019 to start a PhD in the CIBM and LIFMET under the supervision of Dr. Cristina Cudalbu and Prof. Rolf Gruetter. Her thesis research consists in the implementation of diffusion weighted spectroscopy (DWS) and imaging (DWI) at 14.1T to probe brain microstructure alterations in a preclinical model of hepatic encephalopathy (HE). Subprojects of her thesis involve FDG-PET imaging to study energy metabolism in chronic hepatic encephalopathy and validations of PCA denoising techniques for MRS data.

She defended her PhD thesis in 2023, and continued to pursue her research interests as a CIBM research staff till mid-2024. In 2024 Jessie became a Postdoctoral Research Fellow at New York University Grossman School of Medicine.
