He has also worked as a researcher affiliated with the National Agriculture and Food Research Organization (NARO) in various roles from 2001 to 2024. His research lies at the intersection of animal physiology, meat science, and molecular biology, with a particular focus on skeletal muscle biology, muscle fiber types, and bovine physiology. Dr. Muroya’s interdisciplinary work spans transcriptomics, metabolomics, epigenetics, and microRNA research, with recent attention on exosomes and their role in muscle physiology and meat quality. His studies contribute to a better understanding of meat production, muscle development, and functional genomics in livestock. He is a member of several professional societies, including the International Society of Extracellular Vesicles, the Japanese Society of Animal Science, the Molecular Biology Society of Japan, the Japan Society for Bioscience, Biotechnology, and Agrochemistry, and the American Society of Animal Science.
