Biography

I received a B.E. degree in Navigation Technology (Excellent Engineer Education) and a Ph.D. degree in Traffic Information Engineering and Control from Shanghai Maritime University in 2016 and 2021, respectively, where I was a postdoctoral fellow from November 2021 to October 2023. From September 2019 to September 2020, I was a visiting Ph.D. student with the Institute for Systems and Robotics, Instituto Superior Técnico, University of Lisbon, Lisbon, Portugal. Since March 2026, I have also been a visiting scholar with the Communication Theory Lab, Computer, Electrical and Mathematical Sciences and Engineering (CEMSE) Division, King Abdullah University of Science and Technology (KAUST), Thuwal, Saudi Arabia. Currently, I am an associate professor with the Merchant Marine College, Shanghai Maritime University. My current research interests include localization in marine, ocean, and underwater wireless sensor networks, as well as path planning for AUVs/ASVs. As a service to the community, I serve as an editorial board member of Discover Sensors and Discover Oceans, and a youth editor of the Journal of Ocean University of China, Ocean Engineering, Journal of Measurement Science and Instrumentation, Complex Engineering Systems, Oceans, Radioengineering, Electronics, and Signal Processing, and Ocean Development and Management.
