*I got my doctorate in 2000 in the area of Combinatorial Algebraic Topology. In 2004, I got
a permanent position at the University of Seville. In 2005, I published 3 coauthored JCR
papers in the context of Simplicial Topology and Homological Perturbation Theory, I designed
a method to compute Adem and Steenrod cohomological operations from an Eilenberg-Zilber
contraction. The JCR paper “On the cohomology of 3D digital images” published in 2005 was
awarded for being the most cited article in the DAM journal during the years 2005-2010. In 2008 I started a very fruitful collaboration with the Pattern Recognition and Image Processing group led by Prof W Kropastch (TUWien, Austria). That year, I was invited as a 'guest teacher' and because of the stay, we published the paper “Invariant representative cocycles of cohomology generators using irregular graph pyramids” in a JCR Q1 journal. In 2010, I founded the Andalusian group FQM 396: 'Combinatorial image analysis' for which I have been responsible since then. The research line of our group is the search for tools and methods based, among others, on the recent theory of persistent homology. Following the co-direction of the 2013 International DGCI congress in Seville, I was co-editor of a volume in JCR journals DAM and CVIU and I was selected to be co-director of the TC18 committee of Int. Assoc. of Pattern Recognition. From 2011 to 2015 we had a fruitful collaboration with researchers from CENATAV (Cuba) in topological gait recognition. I have been the PI of the national projects “Topología Algebraica Computacional Aplicada a la Visión por Ordenador” and “Topología Algebraica para el Análisis Combinatorial de Imágenes” and I am currently the principal researcher of the national project “Topología Computacional y Aplicaciones” and the autonomic project “Advances in Computational topology and its relationship with neural networks.
I have consolidated collaborations with several research groups in the United States, Austria,
China, France, Italy, and Cuba, making stays through contracts with the university of destination (NCSU in the United States, TU Wien in Austria, and CRIPAC in China) publishing in high-impact journals.
In 2022, I was promoted to Full Professor with accreditation by ANECA in both the areas of Applied Mathematics and Computer Science.
Thanks to the results recently obtained in the relationship between topology and neural networks, we were granted with funding for the national project 'Topología Computacional para el ahorro de energía yla optimización de métodos de aprendizaje profundo para alcanzar soluciones verdes de Inteligencia Artificial (TED2021-129438B-I00) 'and for the EU project ‘REliable & eXplAinableSwarm Intelligence for People with Reduced mObility (REXASI-PRO) (GRANT AGREEMENTNO.101070028)’.
I have been invited as a Plenary Speaker at EACA 2022 (https://www.fue.uji.es/eaca2022) and
to give a talk at the Applied Topology Seminar (https://www.aatrn.net/seminar) and the Topological Machine Learning Seminar (https://www.ub.edu/tml_ub/) among others. I recently joined the Scientific Committee of the Spanish Topology network (https://www.red-topologia.es/).

Sobre los datos de Financiación (proyectos de investigación, contratos, ayudas, etc.):

Solo recogemos de SICA los datos anteriores al año 2000 y no habrá más actualizaciones por el momento desde esta plataforma.
Recogemos de SISIUS los proyectos estatales, autonómicos e internacionales gestionados por la US, siempre a partir del año 2000. Ver política de inclusión en SISIUS para más información.
Proyectos externos: se está creando un procedimiento dentro de la US para recoger de forma ordenada y exhaustiva la documentación relativa a estos proyectos, que se comunicará próximamente. Esto posibilitará que se incluyan convenientemente en SISIUS y después en Prisma. Hasta entonces, no se incluyen en Prisma los proyectos externos, aunque haya alguna referencia en SISIUS.
Ayudas procedentes del Plan Propio: se va a crear un apartado específico para esta financiación. Hasta entonces, no se incluyen las ayudas del Plan Propio en Prisma.

Fecha de la última carga desde SISIUS: 19/12/2024
