Primary research interests include fracture mechanics, probabilistic mechanics, scaling, and structural reliability. Current research efforts focus on deterministic and probabilistic modeling of fracture and fatigue of structures that are made of brittle heterogeneous (quasibrittle) materials such as concrete, fiber composites, tough ceramics, etc. The research goal is to provide a deep understanding of the behavior of quasibrittle materials, and to develop a sound scientific basis for the design of various engineering structures including buildings, infrastructure, aircraft, ships, medical implants, etc.
