My research goals and interests center on large-scale data management and analytics, including interactively querying and mining "big" data, privacy-preserving data analytics, and optimizations in databases and machine learning. I am particularly interested in algorithms which have guarantees in theory, and are effective and implementable in practice. More recently, I enjoy developing algorithms and building systems in the following areas/projects:
AQP-AutoML: I treat AQP (Approximate Query Processing) and AutoML (Automated Machine Learning) as two parallel and alike lines in query processing and machine learning, respectively, with similar or comparable motivations, technical hardness, and usability issues.
Privacy-Preserving Data Analytics: how to process analytical queries and analytics tasks with precision guarantees, while providing data owners with privacy guarantees; studying notions of privacy (e.g., differential privacy) to tune privacy-utility trade-offs; usability.
Large-scale Machine Learning Models: for recommendation systems and other real-world applications.
