Our research can be summarized in two words: Matter and Machine. On the Matter side, Z lab studies far-from-equilibrium physics. They synergistically combine and push the boundaries of statistical and stochastic thermodynamic theories, accelerated molecular simulations, understandable AI/ML/DS methods, and neutron scattering experiments, with the goal of significantly extending our understanding of a wide range of long timescale phenomena and rare events. Particular emphasis is given to the physics and chemistry of liquids and complex fluids, especially at interfaces, driven away from equilibrium, or under extreme conditions. On the Machine side, leveraging their expertise in materials and modeling, his group advances the development of soft robots and human-compatible machines, swarm robots and collective intelligence, and robots in extreme environments, which can lead to immediate societal impact.

Prof. Garcia’s primary research interests are in the realm of granular materials and granular systems. Granular and particulate materials represent some of the most commonly manipulated materials in our society. A fundamental understanding of their behavior at the scale of individual grains or particles has wide-ranging benefits in several fields including civil engineering, geology, additive manufacturing, and planetary exploration. Prof. Garcia uses advanced numerical modeling techniques that can simulate large-strain behavior while also capturing directly the fundamental discontinuous nature of granular systems. His simulations rely on high-performance computing to simulate the interactions of millions of grains within a particle assemblage as the entire mass undergoes large-strain deformation due to phenomena such as earthquake surface fault rupture and trapdoor displacement. This approach allows us to model phenomena at the near-surface such as liquefaction or larger-scale phenomena such as tectonic deformations. The focus on individual particles elucidates the influence of depositional history and soil fabric on the deformation behavior of soils. This line of research advances understanding of how ground surface deformations can impact infrastructure and ultimately aims to improve the resiliency of infrastructure against geologic hazards.

Hugo Casquero is an Assistant Professor in the Mechanical Engineering Department at University of Michigan – Dearborn. His research is focused on developing accurate, robust, and efficient computational methods and using them to solve a myriad of open problems in fluid mechanics, solid mechanics, fluid-structure interaction, biomechanics, and multiphysics. The overarching theme of the computational methods that Dr. Casquero develops is to solve partial differential equations exploiting the new advantages that splines bring to computational mechanics. Dr. Casquero is particularly interested in developing computational frameworks for real-world applications in which experimental measurement of the quantities of interest is too costly or not currently available. Current research activities in his group include achieving a seamless integration between design and analysis of thin-walled structures, studying the dynamics of vesicles, capsules, red blood cells, and droplets under different types of flow, and developing structure-preserving spline discretizations of magnetohydrodynamics to solve problems in fusion energy.
