Earls' research involves the development and application of new computational techniques for the study of important problems involving solids and structures. Coupling the principled treatment of uncertainty with these computational approaches facilitates the solution of complex inverse problems. Such inverse problems arise naturally as part of Earls' research: through the development of novel model-based structural health monitoring strategies.
Earls is the American Editor-In-Chief for the international journal Steel and Composite Structures. He is also a member of the United States Association for Computational Mechanics (USACM) and the International Association on Computational Mechanics (IACM).
