Welcome to the Division of Health Systems Science at Mahidol University's Ramathibodi Medical School. Our division is committed to pioneering advancements in sustainable health systems development through rigorous research and innovative educational approaches. We strive to address the complexities of healthcare delivery systems and policy-making process, leveraging the unique strengths of our multidisciplinary team to foster health equity and improve care quality, locally and globally.
At the core of our mission is integrating systems thinking and complexity sciences, enabling us to develop resilient health systems that meet contemporary and future challenges. Our faculty, including experts in preventive medicine and multidisciplinary academic areas of health policy and systems research, collaborate on interdisciplinary research that bridges the gap between theory and practice. We are dedicated to training the next generation of physicians, health systems scientists and global health leaders, equipping them with the tools to transform healthcare landscapes.
Join us as we work towards a healthier world underpinned by robust and equitable health systems that can adapt and thrive in an ever-changing global environment!
