陈焱凯

I am currently a postdoctoral researcher working with Prof. Philip S. Yu at University of Illinois Chicago. Previously, I was a postdoctoral associate at Cornell University and The Chinese University of Hong Kong. I received my Ph.D. degree in Computer Science and Engineering from The Chinese University of Hong Kong in 2023, supervised by Prof. Irwin King. Prior to that, I completed my M.S. degree at The University of Hong Kong in 2018, working with Prof. Reynold Cheng, and received my B.S. degree from Nanjing University in 2016, mentored by Prof. Qizhi Liu.

My research interest is Data Mining for Information Retrieval and Knowledge Fusion, including the recent following topics:

  • Graph-text fusion. e.g., graph language models, text-attributed graphs.
  • LLM problems, e.g., personalized LLM, retrieval-augmented generation.

I also work on problems including:

  • Information retrieval applications, e.g., search and recommender systems.
  • Large-scale graph data mining and learning problems, e.g., graph neural networks, knowledge graph, self-supervised graph learning.
  • Efficient information retrieval problems, e.g., low-bit quantization, learning to hash.

Feel free to contact me if you are seeking any form of collaboration.
