Welcome to the Integrated Computations and Experiments for Intelligent Materials Design Laboratory (ICE-4-iMD Lab)
The process of materials design has traditionally been a slow and formidable undertaking, relying heavily on the experiences of designers and a significant amount of trial-and-error spanning decades. The complexity of this challenge amplifies when the goal is to engineer a material that exhibits a specific set of properties. Altering the chemistry or microstructure of a material in a haphazard manner to enhance one property often results in the unintended deterioration of others. Furthermore, it’s crucial to acknowledge that the chemistry and microstructure of a material are profoundly influenced by the chosen material processing route.
Our research group is dedicated to addressing these challenges by pioneering advanced computational and experimental techniques, complemented by the power of artificial intelligence. Our overarching objective is to pave a more intelligent and efficient pathway for the design of materials boasting exceptional properties. We concentrate our efforts on materials of particular significance for aerospace applications, energy-related endeavors, and those intended for deployment in extreme environments. This multifaceted approach not only accelerates materials design but also contributes to the development of innovative solutions for an array of critical applications.
