About

Brian R. Donovan is a leading researcher in the emerging field of soft matter engineering, where he explores how materials can be designed to behave like machines. His work sits at the intersection of materials science, chemistry, and robotics, with a core focus on liquid crystalline elastomers (LCEs)—stimuli-responsive materials that undergo dramatic shape changes when triggered by heat or light. Donovan’s most cited paper, “Materials as Machines” (2020, 319 citations), lays the conceptual groundwork for a new paradigm: treating materials not as passive structures, but as integrated systems that harness input power to perform mechanical work. In his highly influential work on LCEs, he has pioneered molecular engineering techniques to sharpen thermotropic actuation (87 citations) and developed microstructured photopolymerization methods for fabricating LCEs in oxygen-rich environments (37 citations). These contributions have enabled stretch-based deformations capable of nearly 20 J kg⁻¹ of output work, advancing applications in soft robotics, health sciences, and adaptive optics. Donovan’s research is defining how we build the next generation of autonomous, shape-shifting materials.
