We build models you can trust to make decisions.

CEAD develops computational methods for materials that fracture, crush, stick and reorganize. The group studies which physical mechanisms a model must retain, and how approximation error affects the decision made from a simulation.

01 Materials That Move

Mechanics and design of field-responsive materials

How electric and magnetic fields interact with microstructure, interfaces and geometry, and how those interactions determine actuation, adhesion and degradation in soft composites.

5 papers 3 researchers Two lineages: coarse graining of field–material coupling since 2016, soft-composite design and adhesion since 2025

02 How Things Break

Fracture and failure in heterogeneous materials

How matrix cracking, interface debonding, particle fracture and contact interactions compete to control strength, toughness, localization and residual load capacity.

03 Error You Can Measure

Reliable scientific AI for mechanics, discovery and design

How residuals, error estimates and targeted high-fidelity solves can determine when a reduced or learned model is accurate enough for inference, optimization or design.
