Biography

Since I started my PhD in 2001 with a project concerning the numerical simulation of turbulent flows on parallel computers, my research has always been related with these topics. Namely, during my PhD I implemented a fully conservative high-order discretization and I developed a Schur complement based parallel Poisson solver suitable for parallel systems with high latencies. This allowed to compute a set of direct numerical simulations (DNS) of buoyancy driven flows. Nowadays, these results are being used by many authors as a reference solution to test the performance of turbulence models. Moreover, in the last year of my PhD, I broaden my research interest into new but related areas: the regularization modeling of turbulence and the extension of the energy-conserving schemes to unstructured grids. Then, in 2007 I moved to the University of Groningen. After more than two years of intense research, my main contributions were twofold: (i) a new class of discrete linear filters for regularization modeling and (ii) a new fully-conservative spatial discretization on unstructured collocated grids. They opened the possibility to use regularizations as a turbulence model in complex geometries and provided a solid mathematical framework for testing subgrid stress models. In 2009 I joined the School of Mechanical and Aeronautical Engineering at the Technical University of Catalonia where I could consolidate my research lines. Moreover, on the basis of my research background, I have worked on the development of better differential operators for Large-Eddy Simulations (LES). Related with this, I derived a new approach to discretize eddy-viscosity models for LES. In 2013 I have been awarded with a Ramón y Cajal research fellowship by the Ministerio de Ciencia e Innovación. I have published 31 papers (13 as first author) in international peer-reviewed journals. My H-index (Scopus-based) is 15.
