Three new people joined the CRM during the month of April, both to work with research groups and with the research support team.
The Centre de Recerca Matemàtica continues to grow with the recent addition of a postdoctoral researcher, a research technician, and a data steward. María da Fonseca is joining the Neuroscience research group as a postdoctoral fellow to work with Alexandre Hyafil on the Computational model for daily fluctuations in psychological states project. The project aims to predict possibly pathological changes in a person’s mood based on the decisions that are recorded daily on their mobile phone. María has a degree in physics and a doctorate from the Instituto Balseiro, in Argentina. Before joining the CRM, she was a postdoctoral researcher at Centro Atómico Bariloche, Universitat Pompeu Fabra, and Universidad de Buenos Aires. Her most recent position was as an associate professor at the Universidad Nacional de Río Negro.
This April we have also welcomed Laura Orrit, who joins the Mathematical & Computational Biology group to work with Josep Sardanyés on the project HENOCANDYN: HEterogeneity and NOise as engines of CANcer evolution: A multiscale DYNamical systems approach. The aim of this project is to further develop our research on the role of heterogeneity in cancer, identify routes to and mechanisms of resistance to treatment, and, finally, evaluate the rational design of combinatorial therapies involving existing drugs and prescribe new therapeutic strategies to overcome the effects of heterogeneity. Laura completed her Bachelor’s in Biomedical Engineering at Universitat Pompeu Fabra in 2021. During the last year of the degree, she performed her Bachelor Thesis, where I was involved in a modeling project focused on the design and development of a computational model to study the dynamics of a heterogeneous population of cancer cells with evolving immunogenicity, in interaction with regulatory and practical T cells.
Finally, the CRM Research Support Team has hired Ariadna Gutiérrez as data steward. Ariadna studied Physics at Universitat de Barcelona, specializing in Fundamental Physics, and she continued her studies with an MSc. in Astrophysics, Particle Physics, and Cosmology at Universitat de Barcelona. She has given dissemination sessions related to Astronomy, which included the observation of celestial bodies, and other dissemination sessions related to Women in Science, aimed to encourage children and teenagers to pursue a degree in Science. Ariadna joins the CRM research support team as a Data Stewart thanks to the INVESTIGO program. As a data steward, her role will be to design and monitor data management plans for research projects, collaborate with the researchers in the collection and maintenance of data, and propose solutions to transform them into FAIR data. She will also contribute to the CRM strategy in open science and to the maintenance and updating of the institutional repository.
We want to welcome them to the CRM community and wish them a very fruitful time with us!

CAVARET 2 brings together 83 researchers on curves and abelian varieties at the Universitat de Barcelona
The second edition of CAVARET, "Curves, Abelian VArieties and RElated Topics", took place at the Faculty of Mathematics and Computer Science of the Universitat de Barcelona from 13 to 17 July 2026. Sixteen invited lectures and ten posters brought together 83...
Mathematics on board: CRM’s demand forecasting model enters service on Barcelona’s H12 corridor
The H12 has run along Gran Via for years. What TMB switched on in July is the set of upgrades designed for it inside eBRT2030, a Horizon Europe project testing electric Bus Rapid Transit in six European cities. Behind it, forecasting passenger demand at every stop...
Dídac Gil Rams defends his doctoral thesis on the splitting of separatrices in generalized standard maps
Supervised by Inmaculada Baldomá and Pau Martín, the thesis proves the existence of chaotic dynamics in a broad family of area-preserving maps and combines classical analysis with computer-assisted proof. The defence took place on 3 July 2026 at the FME (UPC).Dídac...
How to Protect Bacteriophages Without Trapping Them? Mathematics to Improve an Alternative to Antibiotics
Bacteriophages — viruses capable of infecting and destroying bacteria — are considered one of the most promising alternatives to tackle the growing problem of antibiotic resistance. However, for these treatments to work, phages must overcome several obstacles before...
The CRM hosts nine international students for the 10th Barcelona International Youth Science Challenge
Nine secondary school students from six countries spent eight days at the CRM in July, working through four minicourses on fluid dynamics, perturbation methods, iteration and chaos, and randomness from Markov chains to machine learning, plus a session on how...
The Mathematics Behind the Three CRM Lectures at ICM 2026
Three CRM-affiliated researchers, Xavier Tolsa (plenary speaker), Xavier Cabré and Joaquim Ortega-Cerdà, lectured at the ICM 2026 in Philadelphia. Cabré surveyed the regularity of stable solutions to reaction-diffusion equations, including his optimal dimension-9...
Crossing Dimensional Frontiers: a breakthrough in the shape of stable solutions to semilinear elliptic equations
More than twenty years of efforts were required to solve a central problem in the theory of partial differential equations. A body of work developed over decades —and recognized with the Frontiers of Science Award (2023)— culminates in the resolution of an open...
Anna Florio, third CRM Chair of Excellence: billiards, friction, and the value of staying
The dynamicist Anna Florio (CEREMADE, Université Paris Dauphine-PSL) spends the summer at the CRM as the centre's third María de Maeztu Chair of Excellence. She is working with Immaculada Baldomà and Tere Martínez-Seara on billiards in the analytic setting, and on 22...
Hong Wang wins the Fields Medal, a year after her Kakeya lecture at the CRM
Hong Wang (NYU Courant and IHES) has received the Fields Medal at the International Congress of Mathematicians in Philadelphia, alongside Yu Deng (University of Chicago), John Pardon (Stony Brook University) and Jacob Tsimerman (University of Toronto). In June 2025,...
A Conference on Nonlinear PDEs on the Occasion of Xavier Cabré’s Anniversary
One anniversary, eight speakers, July and PDES (People, Discussions, Emotions and Summer) in BarcelonaThe conference Nonlinear PDEs was held at the Institut d'Estudis Catalans (IEC) on 6 and 7 July 2026. While PDEs usually stand for Partial Differential Equations, the...
