Bio. I am a senior researcher & Team Lead (AI for Big Data) in the department of data platform, TEG, Tencent inc. I obtained my Ph.D. degree in Computer Science from Peking University in June 2022, advised by Prof. Bin Cui. And I spent one wonderful semester at ETH Zurich in 2019, working with Prof. Ce Zhang. I have published 30+ papers in the top database (SIGMOD, VLDB), data mining (KDD, WWW) and artificial intelligence (ICML, NeurIPS, AAAI) venues. Besides, I am the designer of several system projects, including OpenBox and MindWare. My research work is recognized by multiple prestigious awards, including the best student paper award at WWW 2022 and the doctoral dissertation award of ACM Beijing.
Research Interests. I have a special focus on building next-gen autonomous solutions/systems to support machine learning and help facilitate data science. My research interests include (1) AI for Big Data: generative data analysis, augmented analysis, NLQ, automatic data annotation & synthesis, synergistic optimization between big data and artificial intelligence, (2) Black-box Optimization: automatic tuning, such as config tuning in big data system, resource optimization and experiment design, (3) Citizen Data Science (AutoDS/AutoML): automatic hyperparameter optimization, adaptive model selection, pipeline search, neural architecture search, and model & data interpretability and (4) LLM-driven decision making: agentic AI methods.
