About Me

I am currently a third-year Ph.D. student at the INtelligent Data Engineering Lab, University of Amsterdam, supervised by Prof. Dr. Paul Groth and Dr. Klim Zaporojets. My research focuses on temporal knowledge graphs and knowledge acquisition, with particular interest in combating temporal degradation in entity linking by integrating dynamic contrastive learning, multimodal fusion, and fairness-aware modeling for low-degree entities.

Before joining UvA, I received my Master’s degree in Control Engineering from Beijing University of Technology in 2022, where I was advised by Prof. Dr. Yong Zhang. My master’s research focused on graph neural networks under power-law distribution and multi-view graph representation learning.

If you are interested in academic collaboration in the areas of temporal knowledge graphs, entity-centric learning, or multimodal information integration, feel free to reach out to me via email at p.zhang@uva.nl.
