Portrait of Zhichen Lai

Associate Research Professor, Fuzhou University, China.

Zhichen Lai (赖志宸) is an Associate Research Professor in the College of Computer Science and Big Data, Fuzhou University, China, and a member of the Fujian Key Laboratory of Network Computing and Intelligent Information Processing. He was selected for the China's Ministry of Education Overseas Talent Program (教育部海外引才计划) in 2025. He currently leads the Data Intelligence and Interdisciplinary Information Group (DIG@FZU).

He received his Ph.D. in Computer Science from Aalborg University (AAU), Denmark, in early 2025, where he also served as a Research Fellow. At AAU, he was advised by MAE and ACM/IEEE Fellow Professor Christian S. Jensen, Dalin Zhang, Huan Li, and Hua Lu.

He was also a Junior Visiting Research Fellow at the University of New South Wales (UNSW) in 2024. He received his M.S. in Computer Science from Sichuan University (SCU) in 2021 under the supervision of Prof. Jiancheng Lv, and his B.S. in Computer Science from the University of Electronic Science and Technology of China (UESTC) in 2018.

Research Areas

My work focuses on data mining and machine learning for structured temporal and spatial data, with an emphasis on methods that remain useful in real-world settings.

01

Spatio-Temporal Data Mining

Representation learning, similarity modeling, and prediction for trajectories, events, and structured temporal data.

02

Time Series and Sensory Data Analytics

Forecasting, imputation, and robust modeling for correlated multivariate time series collected from real sensing systems.

03

Efficient AI Systems

Resource-aware learning and inference methods for models that need to be both effective and deployable.

04

GeoAI

Geospatial intelligence for understanding movement, places, and human activity through data-driven methods.

05

AI for Dental Medicine

Applied machine learning for clinical decision support and intelligent workflows in oral medicine and dentistry through interdisciplinary collaboration.

06

AI for Environmental Science

Learning-based tools for environmental observations and related scientific questions where data, space, and time interact.

Prospective Students

I welcome inquiries from prospective master's students and undergraduate research interns at Fuzhou University, especially first- and second-year undergraduates. If your interests align with the group's research, please email me.

What I Value
  • Initiative Curiosity, self-motivation, and the habit of working through problems independently.
  • Programming A solid coding background; experience with machine learning or deep learning is a plus.
  • Communication Clear communication in both Chinese and English, and a willingness to discuss ideas openly.
  • Ambition An interest in careful, high-quality work; students considering a Ph.D. are especially welcome.
You do not need to be strong in every dimension. Commitment, consistency, and growth matter more than a polished CV.
What You Can Expect
  • Focus Projects are developed jointly within the group's broader agenda, with room for new ideas and initiative.
  • Mentorship Close guidance on coding, experiments, reading, and academic writing, with the goal of helping you become independent quickly.
  • Support Research can be difficult at times. I encourage early communication and steady problem-solving rather than silent struggle.
  • Environment The group provides solid resources and a supportive environment, and I am happy to advise students considering graduate study or a longer research path.
The goal is simple: that your time in the group is demanding, productive, and ultimately worth it.
