The Artificial Intelligence and Machine Learning for Multiscale Modeling (AIM³) Lab is part of the Department of Mechanical and Aerospace Engineering at the University of Texas at Arlington (UTA) and the Institute for Predictive Performance Methodologies (IPPM) at the UTA Research Institute (UTARI). Our lab leverages cutting-edge techniques in multiscale modeling, machine learning, and computational mechanics to pioneer efficient and accurate computational methods and tools. These innovations aim to facilitate the designing, analyzing, and manufacturing of next-generation materials and structures, addressing critical challenges in aerospace, defense, and broader engineering applications.

Current Research Focuses:

  • Data-efficient machine learning for composites modeling
  • Sectionally reinforced beam/shell lattice metamaterials
  • Multiscale modeling and design of aerospace materials and structures
