Xavier Ros Oton

Principal Investigator

Xavier is an ICREA Research Professor at the University of Barcelona since 2020. Previously, he has been Assistant Professor at Universität Zürich, as well as R. H. Bing Instructor at the University of Texas at Austin. He is a mathematician who works on Partial Differential Equations (PDEs). Specifically, he studies the regularity of solutions to elliptic and parabolic PDEs, and he is mostly known for his results on free boundary problems and integro-differential equations. He has been the PI of an ERC Starting Grant (2019-2024) and an ERC Consolidator Grant (2024-2029), and has received several awards for young mathematicians in Spain, including the ‘Premio Nacional de Investigación’ for researchers under 40 in Mathematics and Computer Science. He also received the Scientific Research Award from the Fundación Princesa de Girona, as well as the Stampacchia Gold Medal, an international prize awarded every three years in recognition of outstanding contributions to the Calculus of Variations. In 2022, he was elected member of the Spanish Royal Academy of Sciences.

Marvin Weidner

Marvin Weidner is a postdoctoral researcher in the ERC project “SSNSD” at Universitat de Barcelona, where he previously joined the ERC research team of Prof. Xavier Ros-Oton for the project “EllipticPDE”. Before coming to Barcelona in September 2022, he did his PhD at Bielefeld University (Germany). His research interests lie in partial differential equations with an emphasis on the regularity theory for nonlocal problems.
