Dan Luo | Adobe Digital Experience Platform

About Me

I am an Applied Scientist at Adobe Digital Experience Platform. I received my Ph.D. from the Department of Computer Science and Engineering at Lehigh University, advised by Prof. Brian D. Davison. Before that, I was a Senior Research Engineer at Baidu Web Search (Learning-to-Rank group). I received my M.S. in Computer Science and Technology from Huazhong University of Science and Technology and my B.E. in Computer Science and Technology from Wuhan University of Science and Technology.

Research Interests

Information Retrieval: search and ranking, learning-to-rank, unbiased learning
Recommender Systems: collaborative filtering, multi-modal recommendation
Large Language Models: integration with IR and recommender systems
