I am currently a senior engineer in Tencent. My work spans two fields. One part is in the back-end software development of the advertising system, and the other part is focusing on recommender system for online advertising platform, especially in user interest modeling, CTR prediction. Prior to that, I worked as a software engineer at JD Inc . from July 2018 to November 2019. I designed a genetic algorithm for delivery tasks, optimizing batch allocation and routes, reducing cost and run time. Also, I developed a distributed order task system for the 11.11 festival and a custom order protocol, saving storage costs. I received a double bachelor's degree in Telecommunication Engineering / Marine Technology from Ocean University of China (OUC) in June 2018.

My research interests include data mining, recommendation system. I am also very interested in large language models(LLM) and trustworthy AI, such as the direction of RAG (Retrieval-Augmented Generation), the fairness, robustness, and interpretability of models. I truly believe that this will bring new opportunities and changes to the world and people, especially the residents in poor areas.

I am currently seeking Ph.D. opportunities in Computer Science or Data Science. If you are interested in me, I would be very glad to receive your contact.
