Frank Trujillo joins us as a Postdoctoral Researcher under the supervision of Marcel Guardia. Frank earned his Ph.D. in Mathematics at Université Paris Cité in France in 2020, after completing his M.Sc. at IMPA in Brazil and his B.Sc. at the National University of Colombia. Before joining the CRM, Frank worked as a postdoctoral researcher at the University of Zurich. His research primarily focuses on Dynamical Systems.
Marc Calvo, also a Postdoctoral Researcher, returns to CRM under the guidance of Tim Myers. Marc completed his Ph.D. at CRM in 2019, working on non-classical heat transfer mechanisms in situations involving short length and/or time scales. After his Ph.D., Marc worked in consulting for an IT company, before moving to the UAE to start a position as an Assistant Professor in Dubai and Abu Dhabi. During the three years he spent there, he focused on climate change-related topics, concentrating mostly on heat and mass transfer. He is now starting a postdoctoral position in the Industrial Mathematics group led by Tim Myers, mainly working on the description of adsorption processes.
Fernando Gastón joins the Knowledge Transfer Unit (KTU) at CRM as a Research Technician, under the supervision of David Romero. Fernando graduated with a bachelor’s degree in data science and engineering from the Polytechnic University of Catalonia (UPC) in 2022, where he developed a keen interest in image processing and computer vision. He then pursued a master’s in mathematics at UPC (MAMME), where he developed an interest in dynamical systems and mathematical modelling in general.
Lastly, Marcel Morillas is the other new member of the KTU. Marcel graduated in Physics (BSc) at the Autonomous University of Barcelona (UAB), then studied an M.Sc. Degree in Photonics at the Polytechnic University of Catalonia (UPC), undertook an internship at the Institut für Physik at Johannes Gutenberg University in Mainz, and finally moved to the Knowledge Transfer Unit at the CRM.

Almost every automaton can be reset with a short word
Guillaume Chapuy (Université Paris Cité, CNRS) and Guillem Perarnau (UPC, CRM) have shown that a random finite automaton with n states can, with high probability, be reset by a word of length of order √n log n. The result, published in ACM Transactions on Algorithms, pins the exponent at 1/2, the lower end of a decade of numerical estimates, and addresses the random version of the synchronization problem behind a conjecture Ján Černý posed in 1964 and which still remains open.

ADA: Decoding Brain Signals Misaligned in Time
The study addresses a key limitation of current brain decoding techniques: the difficulty of interpreting internal mental processes whose temporal dynamics vary from trial to trial.Decoding what is happening in a person’s mind from their brain activity is one of the...
Rare curves, many points: Christophe Ritzenthaler and Rachel Pries on their research and the work around it
Christophe Ritzenthaler (Université de Rennes) and Rachel Pries (Colorado State University) both work on curves over finite fields: he hunts curves with as many points as possible, she hunts curves that almost never occur. In conversation with the CRM during their...

A single ball on a fixed table can compute: Eva Miranda and Isaac Ramos prove that two-dimensional billiards are Turing complete
Eva Miranda (UPC, CRM) and Isaac Ramos (ETH Zürich) show that a point particle bouncing inside a planar table with fixed walls can simulate a universal Turing machine, settling a question Cristopher Moore left open in 1990. The result grew out of a master’s project...

Mallorca’s 1820 plague did not behave like a classic bubonic outbreak, study finds
A study in PNAS by Pere Puig (UAB, CRM) and Joana Maria Pujadas-Mora (UOC, ICREA) reports what happens when the daily health records kept in Son Servera and Capdepera during the 1820 outbreak are analysed with a Bayesian epidemiological model: an unusually short...
