Jiajun Cui is a Ph.D. student at Tsinghua University, working on brain-computer interface (BCI) research. He received his bachelor’s degree from Tsinghua University. His research interests lie at the intersection of neuroscience, bioengineering, and brain–computer interfaces (BCIs). He is particularly interested in developing interdisciplinary approaches that bridge fundamental biological mechanisms with advanced neural interfaces and their applications in neuroscience and medicine. By integrating biological understanding with transformative brain-computer interfaces (BCIs), he hopes to contribute to a deeper understanding of the brain and brain diseases, as well as to transformative approaches for the treatment of neurological and neurodegenerative diseases.
