"Scientists study the world as it is; engineers, create the world that has never been." -- Theodore von Karman

Welcome to the Intelligent Computational Mechanics (InCOME) Group led by Dr. Qizhi He. Our group specializes in the convergence of computational mechanics, multiscale and multiphysics material modeling, and scientific machine learning, with main focuses on developing innovative mathematical and computational approaches that facilitate a profound understanding of natural and engineered systems. Our current research interests encompass a range of topics, including advanced numerical methods (FEM, meshfree methods, etc.) for materials modeling, data-driven solid mechanics, damage and fracture mechanics, reduced-order modeling, material inverse design and structural optimization, and physics-informed deep learning for geophysical inverse problems. We are interested in advancing the frontiers of integrating scientific machine learning with computational mechanics.

Our overarching goals are:

1) Advancing the fundamental understanding and predictive capacities of natural and engineered materials, e.g., porous media, composites, biological tissues, and energy storage materials

2) Providing high-performance computational methods and software tools for earth/geo-science in support of environmental health, cleaner energy, and national security

3) Improving the sustainability of civil structures and infrastructure under extreme conditions due to climate change and anthropogenic activities
