About

Ruohong Shi is pioneering the frontier of programmable soft matter, where DNA instructions drive autonomous shape-shifting materials. Her research centers on DNA polymerization motor gels—a novel class of hydrogels that respond to biochemical cues without external wires or devices. By embedding DNA duplex crosslinks into polymer backbones, Shi has created multicomponent gels capable of swelling, bending, and reconfiguring in response to specific sequence instructions. Her most cited work, "Multicomponent DNA Polymerization Motor Gels" (2020, 25 citations), established a foundational platform for biosensing, smart medicine, and soft robotics. In "Programming gel automata shapes using DNA instructions" (2024, 8 citations), she demonstrated multi-step shape changes controlled purely by molecular signals, a breakthrough for autonomous reconfigurable devices. Her studies on swelling characteristics (2023, 3 citations) and shape-shifting microgel automata (2022, 2 citations) further elucidate the mechanics of these responsive materials. Shi’s work bridges molecular information processing and materials engineering, offering a blueprint for next-generation soft robots, tissue scaffolds, and drug delivery systems that mimic biological transformation.
