About the Research

Research Theme

Synthesis of high performance hydrogels and soft matter. Especially focused on tough gels, self-evolving gels, low friction gels, adhesive gels, biocompatible gels.


Polymer gel, Biomaterials, Regenerative medicine

Research Outline

The ultimate goal of our research is the development of strong and highly functional gels that outperform soft tissues of the body, such as muscle, cartilage, and tendons. In addition, we try to find applications for these materials in a variety of scientific fields, including in the medical field. Together with ICReDD, we want to design these materials on a molecular level to create metabolizing, self-growing, and thus adaptive tissues.

Drawing inspiration from biological systems, we make assumptions on the reason behind their function and try to create artificial structures with comparable or superior characteristics. We then verify the assumptions experimentally and explore the artificial system’s physical properties. The results of this inform the next round of assumptions and artificial systems.

The Researcher’s Perspective

Being a scientist is a unique job. It requires creativity and devotion, much like an artist, and allows following one’s interest freely. Discovering or inventing something in this process is very rewarding. I was inspired to become a scientist by reading, as a child, biographies of researchers, especially of Marie Curie. As a girl, I was encouraged by the fact that she could achieve so highly in times that difficult for women. But even today, I hope the number of female Ph.D. students and scientists in chemistry will increase more and more.
