Hi, welcome to my professional webpage!
I am a tenured assistant professor and Delft Technology Fellow at the Delft Institute of Applied Mathematics (DIAM), TU Delft. My main research area is the analysis of partial differential equations arising from the applied sciences.
Before joining TU Delft in October 2022, I was a postdoc at University Lyon 1 (2019-2021) and University of Vienna (2021-2022). I obtained my PhD jointly from the University of Granada and the Basque Center for Applied Mathematics in October 2019. My PhD supervisor was José A. Cañizo.
In August 2023, I was awarded a Veni grant from the NWO (Dutch Research Council) with my project abbreviated "MetaMathBio".
I co-organise the seminar in PDE and Applications at TU Delft. Moreover, I am one of the founding members of the Special Activity Group (SAG) on Analysis of PDEs in the Netherlands and I serve in the board of the national NDNS+ cluster to represent TU Delft. I amd also a member of the Diversity & Inclusion Committee of DIAM and Delft Young Academy.
Upcoming scientific events:
Collective movement and pattern formation: Biology, modelling and analysis, 27-30 July, 2026, ICMS, Edinburgh, UK (invited talk).
Wave-Ned 2026: Conference on Analysis, Modeling and Numerics of Waves, 26-28 August 2026, TU Delft, The Netherlands (co-organiser of the minisymposium MS19: From Wave Turbulence to Kinetic Theory).
