Outline Activities
Earlier in my graduate training, under the supervision of Prof. Kang Moo Huh, I learned how to develop hydrogels for drug delivery and the treatment of degenerative diseases. This experience solidified my intention to pursue a career in biomaterial design. To further this aim, I pursued a Ph.D. under the guidance of Prof. Tooru Ooya. In this program, I acquired skills in the molecular design of advanced materials, the organic synthesis of biocompatible compounds, and the characterization of biomaterials' physical properties. Additionally, I have three years of experience as a postdoctoral fellow at the University of Illinois at Chicago, working in Prof. Jae-Won Shin’s group. Since joining Dr. Shin’s group, I have been learning new skills to improve mesenchymal stromal cell (MSC)-based therapeutics through biomaterial design in the context of tissue regeneration and fibrosis. Currently, at Kyushu University, I am engaged in a study to investigate how a novel biomaterial affects stem cell behavior, particularly regarding morphology and differentiation. The study aims to explore how the intermediate water can be regulated by the biomaterial while maintaining other factors such as elastic modulus and surface topology. This research has potential applications in fields such as tissue engineering, regenerative medicine, and drug discovery.

Academic Activities
Educational Activities
I have been guiding our lab members in their research and experimental activities, teaching them how to set up experiments and present their work effectively. As many of them are undertaking these activities for the first time, I start with the fundamentals. This includes how to locate relevant papers, develop ideas, engage in brainstorming, execute experiments, and analyze data. Problem-solving is also a critical skill; when students encounter issues, I teach them strategies for finding solutions. Additionally, understanding prior research is essential, so I instruct students on how to find previous studies and papers. This approach not only helps them tackle current problems but also lays the groundwork for advancing our research.
Professional and Outreach Activities
My academic journey, spanning Korea, Japan, and the United States, has afforded me a unique perspective in fostering social contributions and international collaborations. In this essay, I'll detail how my educational and research experiences across these diverse cultures have deepened my understanding of social dynamics, broadened my global outlook, and equipped me with the skills necessary for significant contributions to social and international projects. Throughout my journey, I've built a vast network of colleagues, mentors, and collaborators in these countries, creating a wealth of opportunities for partnerships aimed at addressing societal challenges. By leveraging these connections, I am able to unite experts from various fields, institutions, and nations to tackle complex issues. The varied perspectives and expertise in my network encourage cross-cultural exchanges, share best practices, and foster the development of innovative solutions, amplifying our collective impact..
