Department of Aerospace Biodynamics

Welcome to the Department of Aerospace Biodynamics at the Fourth Military Medical University, Xi'an. We are a community of 14 researchers, M.S. and Ph.D. graduate students actively engaged in innovative research, discovery, and training in aerospace medicine.


The mission of our Department of Aerospace Biodynamics is to fully integrate the cutting edge of engineering and physiological sciences with state of the art biology to advance our understanding of problems in aerospace medicine, and to use that science to drive the development of training and countermeasure devices.


The research in our Department covers a wide range of topics with special emphasis on the physiological and biological effects of acceleration or microgravity and studies of countermeasure technique. Our Department has 5 laboratories (including Lab of Gravitational Physiology, Lab of Space Cellular and Molecular Biology, Lab of Bed Rest Study, Lab of Biomechanics and Lab of Centrifuger).


Our Department aims to provide graduate students with an interdisciplinary view of the complex aerospace biodynamics problems facing modern medicine, and the specific knowledge and skills necessary for undertaking advanced research and development in this field.


Our research is supported by public funding agencies, and our interdisciplinary research programs are complemented by interactions with students, staff, and faculty in other departments in the School of Aerospace Medicine, Chinese Astronaut Research and Training Center, and Institute of Aviation Medicine. For our teaching activities, we offer lecture and laboratory courses for medical students and graduate students as well as research opportunities for graduate students, undergraduate students and visiting scholars.


I hope you find our site to be a useful window through which you can glimpse into the life of the Department and learn about our graduate program and research projects.
