Overview

Research Challenges

Bridging length scales: linking nanoscale polymers, mesoscale structures, and macroscale materials

Limits to measurement tools: capabilities of current computational and experimental characterization techniques

Developing theoretical models: applying fundamental principles instead of intuition or inspiration to inform design
