Javier Murillo
Phd in 2006. The research work has focused on the development of simulation tools with application to environmental flows both from a practical point of view and from the perspective of the development of new mathematical methods to improve results. Both lines have generated numerous publications in high impact journals and prestige, and the results cover different aspects to the world of engineering and the environment. A post-doctoral year stay at the University of Trento in 2007.
Mario Morales-Hernández

His scientific contributions are in computational hydraulics, including the development of new efficient numerical methods for shallow water equations, such as Large Time Step schemes  or coupled 1D/2D models, and optimization and control in fluid simulations by means of adjoint-based methods. He is also well-versed in HPC techniques, being the developer of TRITON and SERGHEI, both open-source hydraulic simulation codes for large-scale problems. Both codes have gained recognition and adoption within government initiatives, demonstrating their practical value in hydraulic modeling and flood prediction.

Adrián Navas-Montilla
Assistant professor
His research activity focuses on the generation of efficient numerical schemes with application to geophysical flows and hemodynamics. He is working on the design of very high order WENO and Discontinuous Galerkin schemes using ADER and RK integrators, based on augmented Riemann solvers. Some of these have been successfully applied to the simulation of resonant phenomena in channels with lateral cavities, in collaboration with other research institutions. He is also interested in the study of numerical shockwave anomalies in the framework of Finite Volume schemes.
Sergio Martínez-Aranda
Assistant Professor

His research interests are focused on the development of high performance mathematical and numerical models to predict geomorphological processes involving sediment transport, complex non-Newtonian behaviour and transient boundaries. He desings multi-CPU and GPU-accelerated Effcient Simulation Tools (EST) with direct application to sediment transport in rivers and coastal areas, highly-erosive floods, dam breachs, debris flows and muddy slurries, oil spills and lava flows.

Isabel Echeverribar
PhD student

Her activity is mainly focused on the development of numerical methods for the simulation of unsteady surface flows. With a background focused on High Performance Computing applied to 2D models for flood simulations, she is now researching new models for oil spills in coastal flows. Some of her work is oriented towards two-layer models to simulate both oil and water, while other research is carried out to analyze the importance of non-hydrostatic terms in representing these coastal flows.

Pablo Solán
PhD Student

His research activity focuses on the implementation of reduced-order models (ROM) based on the proper orthogonal decomposition (POD) method and with application to transport equations. An alternative ROM capable of predicting solutions beyond the training time has been developed, thus overcoming one of the major limitations of the POD method. He is also interested in  the study oh the performance of high-order schemes, such as WENO schemes, via spectral analysis in the framework of iLES methods.

Juan Mairal
PhD Student

His research activity is focused on the formulation of 1D junctions of flows as inner boundary conditions in order to simulate large networks as efficiently as possible. This is applied both to shallow free-surface flows in hydrodynamic settings and to the human vascular system, with special attention to the venous system and the sonic flow transitions that may occur in it.

Pablo Vallés
PhD student

His activity is mainly related to the design and application of an Eulerian/Lagrangian debris transport model for flash flood prediction. The development of this model aims at simulating the transport of objects from small size, such as seeds or microplastics, to large bodies, such as cars or woods. He is also working on the implementation and application of modeling techniques to reduce the computational cost of numerical simulations.

Javier Fernández-Pato

Soil and Water. EEAD-CSIC, Zaragoza. His research interests are focused on the development of implicit numerical methods for the simulation of unsteady surface and groundwater flows, coupled with hydrological processes. He also works on the implementation of efficient linear matrix solvers as well as the application of novel mathematical techniques to hydraulic/hydrologic simulation.

Research interests focused around developing and applying computational models and High-Performance Computing (HPC) for coupled surface and subsurface ecohydrology and geomorphology. His work aims to develop, improve and apply a variety of multidimensional HPC-enabled solvers for environmental, hydrological, hydraulic and geomorphological applications, both for forecasting and process understanding. His work also touches HPC aspects such as performance-portability and novel aspects of numerical methods such as adaptive grid refinement and high order numerical methods for such flows.
