Xavier Ros Oton, ICREA professor-researcher and professor at the University of Barcelona, ​​was distinguished by the Guido Stampacchia Gold Medal. This international prize, awarded by the Union of Italian Mathematicians, rewards experts up to the age of 35 whose research work is important in the field of variational analysis and its applications.

“The Stampacchia medal is a great international award, one of the most important in my field of research. Previous laureates are professors from ETH Zurich, Princeton, Columbia and Courant Institute of Mathematical Sciences (New York), and one of them received the Fields Medal in 2018. For me, it’s an honor to be on the list of laureates. , notes Ros Oton.

The jury defined the researcher as “world leader in the field of partial differential equations in variational theory”, a field in which he has carried out several new fundamental techniques. Ros Oton is the first researcher in Spain to receive this prestigious international prize, awarded every three years.

Partial differential equations play a central role in many fields of science and engineering, as well as in mathematical problems of geometry and probability. “PDE research has two sides, computational and applied parts, to the more theoretical part of mathematical research, on which I am working,” notes the laureate. Mathematical research on PDEs began to develop at the start of the 20th century and has grown in recent decades. “However, -says Ros-, there are still many fundamental and important questions to be answered, for example, concerning the peculiarities of the solutions in several types of PDE.”

Xavier Ros Oton joined the Faculty of Mathematics and Computer Science at UB this year, where he heads the research group on partial differential equations. He says “there are two things that helped me decide to come back to Barcelona: on the one hand, the ICREA program on recruiting international talent, and on the other hand, the fact that the Department of Mathematics and Computer Science at UB is going on a good time, with great people and energy ”.

Mathematics, a versatile diploma for the future

Over the past few years, we have seen how math and statistics have become the most up-to-date profiles in business. “Today, mathematics plays an essential role in decision-making and the optimization of sectors, and this trend is growing. In fact, my former colleagues have different jobs: from advisers or data analyzers in different sectors, to programmers for Google or Instagram, including people with a doctorate in mathematics, physics or economics. This versatility makes mathematics one of the diplomas with the most future ”.

On the other hand, mathematics is among the best degrees chosen by students with higher marks. “I would say to current students that training does not stop with the last years of the license, I would encourage them to continue their training, whether in business or at university, or as high school teachers.”

Ros Oton has received several prizes for young researchers in mathematics, including the José Luis Rubio de Francia Prize from the Royal Spanish Society of Mathematics (RSME) and the Antonio Valle Prize for Young Researcher from the Spanish Society of Applied Mathematics (SEMA). In 2019 he was awarded the Premi Fundació Princesa de Girona for Scientific Research 2019. He was a lecturer at the University of Zurich and HR Bing instructor at the University of Texas at Austin (USA). Currently, he is the Principal Investigator of a European Research Council Start-Up Grant (2019-2024).
