Rate My Professor Ruiz Baier

Professor Ricardo Ruiz Baier is Professor of Computational Mathematics and ARC Future Fellow in the School of Mathematics, Faculty of Science at Monash University, where he serves as Director of Postgraduate Studies. He obtained his PhD in Mathematical Engineering from Universidad de Concepción, Chile, in 2008, with a thesis titled Numerical methods and analysis for degenerate parabolic equations and reaction-diffusion systems. Before joining Monash, he held the position of Departmental Lecturer in Numerical Analysis at the Mathematical Institute, University of Oxford from 2015 to 2019, Senior Researcher at the University of Lausanne from 2013 to 2015, and Postdoctoral Fellow at the École Polytechnique Fédérale de Lausanne from 2009 to 2013.

Ruiz Baier's research centers on the design, analysis, and implementation of numerical methods for partial differential equations, including mixed finite element and finite volume methods, augmented formulations, error estimation, adaptivity, and solutions to saddle-point problems. His expertise extends to applications in multiphysics phenomena such as multiphase flow and transport in porous media, cardiac electromechanics, population dynamics, transmission in continuum mechanics, and large deformations of soft tissues. He was awarded an ARC Future Fellowship in 2023 for four years on the project Next-generation methods for transport in poroelastic media with interfaces. Key publications include Integrated heart—coupling multiscale and multiphysics models for the simulation of the cardiac function (2017, 333 citations), Locking-free finite element methods for poroelasticity (2016, 166 citations), Thermodynamically consistent orthotropic activation model capturing ventricular systolic wall thickening in cardiac electromechanics (2014, 166 citations), and recent contributions such as Virtual element methods for Biot–Kirchhoff poroelasticity (2025) and Primal-mixed finite element methods for the coupled Biot and Poisson–Nernst–Planck equations (2025). With over 4,000 citations on Google Scholar, his work has made substantial impact in numerical analysis and scientific computing. He serves on the Scientific Committee of MATRIX and co-chairs MoCaO.
