UC San Diego Database Lab

The Database Lab at UC San Diego is one of the leading academic research groups in the field of data management, spanning the major themes of theory, systems, languages, interfaces, and applications, as well as intersections with other data-oriented fields. Areas of particular strength include database theory, data integration, semistructured data, heterogeneous data, hardware-conscious data processing, query processing and optimization, data exploration, data analytics, and machine learning systems. Application areas of particular interest have included healthcare, Internet of Things, and social media.

We are a part of the Computer Science and Engineering department. DB Lab faculty are also affiliated with other research groups, including the Theory Group, Artificial Intelligence Group, and Center for Networked Systems, as well as with the Halicioglu Data Science Institute.

Affiliated Faculty

Kamalika Chaudhuri [Google Scholar]

Kamalika's research interests lie in the area of machine learning. Specifically, much of her work is on privacy-preserving machine learning and unsupervised learning, but she's also broadly interested in a number of topics in learning theory, such as confidence-rated prediction, online learning, and active learning.

Babak Salimi [Google Scholar]

Babak's research interests are in data management, causal inference, responsible data science and data ethics. His research seeks to unify techniques from theoretical data management, causal inference and machine learning to develop the necessary conceptual foundations for decision-making and policy evaluation from complex relational data, algorithmic fairness, explainability and accountability.

PhD Students and Postdocs

Rana Alotaibi

Rana's research interests lie in hybrid stores databases, large scale data integration and scalable self tuning database systems.

Supun Nakandala

Supun's research interest lies broadly in the intersection of Machine Learning and Systems, an emerging area which is also known as Machine Learning Systems. His current work involves implementing efficient, scalable, and reliable algorithms, systems, and abstractions for Deep Learning powered Machine Learning workloads.

Ainur Smagulova

Ainur's research interests lie at the intersection of the theory and applications of databases and big data management systems. Currently, she is focused on data processing for massively parallel systems, more specifically, parallel computation of queries over large graphs and their complexity.

Vraj Shah

Vraj's research interest lies in accelerating the advanced data analytics life cycle by simplifying data sourcing for Machine Learning (ML) and making it easier and cheaper to deploy ML powered data analytics applications, improving both efficiency and usability of ML for data science.

Marysia Tran

Marysia's research interests lie in logic and database theory.

Xiuwen Zheng

Xiuwen's research interests lie in heterogeneous data management, polystore system, query optimization and AI in DB.

Research Projects

Current Projects

Triptych

An end-to-end data system for sourcing data and features, as well as specifying, optimizing, and managing the ML model selection process.

Genisys

Deep learning-powered database perception to enable data systems to see and hear unstructured data for unified type-agnostic analytics.

Forward

A declarative, rapid development framework for data-driven Ajax reports and applications. Rich visualizations and collaborative workflows require only a few lines of SQL-based code and visualization/interaction markup.

Past Projects

  • Delphi: DELPHI is a platform that enables integrated access and analysis of all data relevant to health. This platform promotes a more rapid development of empowering, data-driven health apps and tools by a broad community of health-related software developers.
  • SQL++ and Middleware: SQL++ is a highly expressive semi-structured query language that encompasses both the SQL and the JSON data model. SQL++ is SQL backwards-compatible. The Configurable version of SQL++ includes configuration options that formally itemize the semantics variations that language designers may choose from. We use SQL++ in FORWARD's middleware query processor.
  • Other projects: Links coming soon.
