Reseach Scientist
Asahi Kasei Corporation, Japan
My name is Kohei Yabuuchi. I received my Ph.D. in Biomaterials and Bioengineering from Tokyo Medical and Dental University. My research journey has been driven by a passion for advancing pharmaceutical science and engineering.
Currently, I serve as a research scientist at Asahi Kasei Corporation, where I am committed to pioneering new materials in the pharmaceutical field. My primary focus lies in the development of hyaluronic acid nanogel, commercially known as Sonanos™, alongside my exploration of drug delivery systems and tissue regeneration materials.
Over the past nine years, I have been deeply involved in the comprehensive development of Sonanos™ technology. This includes the essential product design to maximize its functionality, the establishment of innovative industrial-scale manufacturing processes, and the advancement of formulation technologies using Sonanos™. I have led my team through numerous breakthroughs, such as:
・Designing various product grades of Sonanos™
・Developing novel synthetic processes
・Establishing new evaluation methodologies
・Proposing and constructing in vitro release models for sustained-release formulations
・Elucidating release mechanisms
・Generating extensive PR and technical data
・Driving application development, particularly in cancer vaccines, as well as parental, oral and suspension formulations
・Filing over ten patent applications related to Sonanos™ technology
These efforts have contributed to a broad and impactful body of work. Currently, my role has evolved to include the design of clinical trial manufacturing processes, technical support for clients, and formulation development assistance.
Prior to my current role, I earned my Master’s degree in Applied Chemistry from Tokyo Institute of Technology, which laid a strong foundation for my career in innovative materials research.
I am enthusiastic about collaboration and innovation in the pharmaceutical field and look forward to contributing further to the advancement of our industry.
Thank you for this opportunity to share a glimpse of my journey with you.
