Simulation Laboratory for Innovative Materials Engineering
Our Goal: Molecular Engineering of Sustainable High Performance Soft Materials
Welcome!
The O'Connor Lab is a research group in Carnegie Mellon University's Department of Materials Science and Engineering. We apply theoretical and computational tools to understand and control the microscopic molecular mechanisms that govern the macroscopic material behaviors of polymers and soft materials. We are interested in using these discoveries to guide the creation of more sustainable, durable, and reliable plastic materials, and to improve the efficiency of soft material manufacturing and recycling methods.
Modeling Soft Materials from Molecules to Manufacturing
Our research approach was born within the Materials Genome Initiative, and our approach to material modeling is inherently multi-scale. We apply high-performance physical modeling at molecular, mesoscopic, and continuum scales to tackle challenging fundamental problems in soft material dynamics, mechanics, design, and manufacturing.
