Xiuyun Liu

Brain diseases are a major challenge facing the world.

Xiuyun Liu’s research mainly focuses on applying various biomedical engineering technologies into the critical care medicine field. She has undertaken a number of scientific research projects, and in 2021, as the project leader, presided over a key project of the "Biological Information Fusion" national research, with a total project funding of 175 million and a central government funding of 40.94 million. She is committed to solving the research and application of key technologies to make a technological breakthrough in high-performance non-invasive brain-computer interface.

Liu developed a multi-window algorithm for continuous optimal cerebral perfusion pressure (CPPopt) determination, which has been applied by Johns Hopkins Hospital and conducted in a clinical trial in the Belgium, the Netherlands, and the UK. She introduced cerebral spinal fluid perfusion technology to mainland China for the first time, which has been widely applied in clinical bedside for hydrocephalus patient diagnosis in Tianjin and Beijing. The method greatly saves patients’ costs by shortening the diagnosis time from 3 days to 30 minutes. More than 300 patients have benefited from this technology so far and the number continues to grow. She also developed several parameters for cerebral vascular function and cerebral autoregulation monitoring, which have been implemented into a professional ICU software ICM+, and the software has been installed in more than 100 hospitals worldwide.

Currently, Liu is leading a team that is making technological breakthroughs in areas such as cerebral oxygen monitoring and anesthesia monitoring, and developing domestic high-end medical devices, laying the foundation to seize the technological high ground in corresponding fields.
