OSAKA GAS Co., Ltd. | Japan
Mr. Shohei Katsuya is a dedicated Researcher at the Advanced Technology Research Institute of Osaka Gas Co., Ltd., where he has been contributing to cutting-edge scientific advancements since April 2021. He holds a Master of Agriculture degree from Kyoto University, earned in March 2021, and has since developed a strong research focus on the physiological functions of beta-hydroxybutyrate (BHB). His work revolves around understanding how BHB influences metabolic regulation, ketone body pathways, and physiological responses related to obesity and visceral fat accumulation. As metabolic disorders continue to rise globally, his research addresses critical scientific questions with direct implications for human health, nutrition, and disease prevention. Shohei has played an active role in developing nutritional strategies aimed at improving metabolic outcomes, collaborating with academic institutions, and supporting multidisciplinary projects that advance metabolic health science. Between 2023 and 2025, Shohei has authored five peer-reviewed publications in reputable international journals, including Obesities, Journal of Nutritional Science and Vitaminology, Bioscience, Biotechnology, and Biochemistry, and Nutrition. These publications collectively reflect his commitment to scientific rigor and his growing influence in the fields of nutritional science and metabolic physiology. His research output has received 18 citations to date, according to Scopus metrics (as of November 2025), and his current h-index of 2 indicates early yet solid scholarly impact within a short timeframe. His contributions provide valuable insights into ketone-body-driven metabolic pathways, opening possibilities for new therapeutic and dietary approaches. Shohei’s research activities align strongly with the mission of advancing evidence-based nutrition and metabolic science, demonstrating originality, societal relevance, and a high level of research integrity. His projects emphasize translational potential—particularly in dietary interventions for visceral fat reduction—and reflect an understanding of both biochemical mechanisms and practical applications for health improvement. Through continuous collaboration with academic partners, Shohei has strengthened his ability to transform scientific concepts into meaningful innovations that address modern health challenges. His commitment to excellence, ethical research practice, and impactful scientific contribution make him a strong candidate for the Excellence in Research Award. Shohei declares that all information provided in this application is accurate and authentic to the best of his knowledge, and he remains fully committed to upholding the values and standards of the International Research Awards.
