About

Kei Fujiwara is a pioneering researcher in bottom-up synthetic biology, whose work focuses on constructing artificial cells that mimic the dynamic behaviors of living systems. Her key research areas include spatiotemporal patterning, reaction-diffusion (RD) waves, and the controlled assembly of synthetic cellular machinery. Fujiwara’s major contribution lies in engineering defined protein expression systems within artificial cells to regulate complex, self-organizing patterns—a fundamental step toward understanding developmental differentiation and homeostasis. Her 2019 paper on spatiotemporal patterning (42 citations) demonstrates how gene-derived elements can produce higher-order collective motions, while her 2022 work on controlling RD wave periodicity (11 citations) advances the design of nano- and micromaterials for dynamic regulation. Notably, she has also developed innovative methods for fusing giant unilamellar vesicles (GUVs) using calcium and polyethylene glycol, enabling the remote activation of transcription-translation systems. Earlier, she constructed a remote-controlled supramolecular micro-crawler, a lipid-membrane-based micro-robot propelled by magnetic fields. With her interdisciplinary approach, Fujiwara is shaping the future of synthetic cells and bioinspired microrobots.
