Research Topic on our Lab.
“Reproducing Life-like Behaviors using Inanimate Materials, and Uncovering Fundamental Mechanisms of Life-like Phenomena”
We challenge to elucidate the universal mechanism by reproducing the characteristic phenomena observed in biological systems without using living materials. In our lab., we focus on “self-propelled motion”, “rhythmic phenomena”, and “pattern formation phenomena”, and try to reproduce such behaviors in non-living systems. Furthermore, we construct mathematical model reproducing such characteristic phenomena and clarify the fundamental and universal mechanism of them.

Collaboration
We are mainly collaborating with people who have complementary relationships with our lab.. For example, I am not mathematician and be hard to analyze using advanced mathematical analysis. So, when I have a mathematical model, I consult with a mathematician for joint research. In another case, if molecular analysis is needed, I consult with an expert in analytical chemistry. I have been offered joint research in search of knowledge of nonlinear systems.
In recent years, a Chinese material chemistry expert has provided results for a self-driving system for fine metal particles, but we have been consulted and conducting joint research because we cannot clarify the analysis method and mechanism. I am also interested in collaborative research with biological researchers.
If you are interested, please contact us.
