Since 2015, I have held the position of full Professor at the Complutense University of Madrid in the Department of Theoretical Physics. From 2019 to 2023, I was a faculty member of the Instituto de Ciencias Matemáticas (ICMAT). From 2020 to 2022, I served as a member of the Government Board of the Royal Spanish Mathematical Society (RSME).

My areas of expertise lie in Mathematical Physics and Applied Mathematics. Specifically, I have been significantly involved in the Theory of Integrable Systems, as well as the field of Orthogonal Polynomials and Special Functions. Recently, we have proven a spectral theorem à la Favard for bounded banded operators, extending the well known spectral Favard theorem for Jacobi matrices. Also, my research interests have expanded to encompass topics such as random walks and Markov chains beyond birth and death, as well as the application of the Riemann—Hilbert problem in characterizing non-Abelian Painlevé discrete equations. Additionally, I have utilized the Gauss—Borel factorization of semi-infinite Gram matrices to derive Christoffel and Geronimus formulas in various extended orthogonalities. I have conducted extensive studies on orthogonalities in diverse forms, including discrete, matrix, multivariate, mixed multiple, and Sobolev. Exploring the connection between new integrable systems or families of solutions and these orthogonal polynomials has also been a significant focus of my research.

I have coauthored 128 scientific publications, out of which 101 are published in JCR journals, with 56 of them in first quartil. Presently, I am leading a Spanish National Plan project, and in the past, I have led two additional Spanish National Plan projects, all within the field of Mathematics. Furthermore, I have been a member of six international research projects and ten national research projects. I have supervised three PhD theses and I am currently supervising two more. Additionally, I have organized R&D&I activities, including international scientific conferences.

Together with Luis Martínez-Alonso, we are in the final stages of completing a comprehensive book on Boundary Value Problems for Linear Partial Differential Equations. Announcement. We are thrilled to share that this book will be published by CRC Press, a renowned and respected publisher in the academic community. Our aim in writing this book is to provide a valuable resource for students, researchers, and practitioners interested in delving into the fascinating realm of linear partial differential equations and their boundary value problems.

I have supervised 8 Master's Theses, 9 Bachelor's Theses, and 2 academically directed projects. Additionally, I have been responsible for 40 teaching groups, all within the field of Mathematical Physics and Mathematics. My teaching focuses on courses related to partial differential equations in Mathematical Physics, including boundary value problems, as well as the fundamentals of complex analysis in one variable and its applications. I have also taught postgraduate courses covering topics such as group theory, Kac-Moody algebras, functional analysis, integrable systems, and orthogonal polynomials. Furthermore, I am the author of two teaching manuals on Differential Equations and another one on Complex Analysis. I have actively participated in 5 teaching innovation projects, and for four years, I served as an evaluator of educational innovation projects at the Autonomous University of Madrid. Additionally, I have contributed to pre-university orientation activities and collaborated in university entrance exams. Specifically, I have served as a member twice, deputy secretary three times, and vice president eight times at various venues.

I have organized 6 meetings on the European Higher Education Area, published 2 works on European convergence, and delivered 9 presentations on university teaching. I actively participated, representing the area of Theoretical Physics, in the work group responsible for developing the current study plan for the Physics degree at the UCM. Lastly, I have served on the executive committee of MiriadaX, a MOOC platform promoted by Universia. In terms of administration, I have held various positions, including Vice Dean, advisor to the Vice Chancellor for the Direction of the European Convergence Office, Director of the Department of Theoretical Physics II, Deputy Vice Chancellor of Innovation, and Coordinator of the Doctoral Program in Physics. I am an active member of the Faculty Board, the University Senate, and the Statutes Commission of the University Senate.
