Welcome to the site of Marino Arroyo's research group. I am a full professor at the Universitat Politècnica de Catalunya, Research Center in Numerical Methods in Applied Science and Engineering (LaCàN), and partially affiliated at CIMNE and IBEC. I am also part in the Institute of Mathematics of UPC-BarcelonaTech (IMTech).
We develop theoretical and computational models to quantitatively understanding the mechanobiology biological interfaces across scales, to rationally manipulate active living materials, and to engineer new bionic and bio-inspired materials.
The core of our current research revolves around mathematical and computational modeling to understand complex mechanical and mechano-chemical phenomena governing the dynamics of biological interfaces, in close collaboration with experimental groups. Our work covers biological membranes and their interactions with proteins, active matter and the cytoskeleton, cell mechanobiology, and tissue mechanobiology, with a particular interest on spontaneous pattern formation in these systems. We also study the motility of Euglena, a unique protist, and how to develop new morphing materials inspired by it. We often develop complex models for soft and active matter based on Onsager's variational formalism of irreversible thermodynamics.
Previously, we made contributions to multiscale modeling of 2D materials and developed the maximum-entropy approximation schemes used in computational mechanics. We have also been interested in various aspects of fracture mechanics, of the integration of manifold learning in computational mechanics, the connection between molecular and continuum mechanics, phase-field models, or the mechanics of thin shells.
