Announcement

Welcome

I'm an Assistant Professor in the data management group of the Computer Science department at Brown University. My research focuses on interactive data exploration and Big Data management systems. This means my research group and I work along the whole system stack from the user interface over novel machine learning and new statistical methods to the ''guts'' of database systems.

For example, with Vizdom we are exploring a new user interface to fundamentally enable layman users to explore and build complex (ML) models, whereas with IDEA and Tupleware we develop new techniques to power the new workloads created by the next generation of user interfaces like Vizdom; the main challenge here is to to ensure interactive latencies regardless of the data size and type of operation. Similarly our work on auto-tuning for machine learning algorithms, MLbase & TuPAQ, or our work on quantifying the risk factors of missing data, the unknown unknowns, aim to help users to make faster and more sustainable discoveries.

Current Research Interests

  • Systems for Interactive Data Exploration
  • Infrastructure for rack-scale analytics and machine learning
  • Transaction processing over high-speed networks
  • New consistency and concurrency control models
  • Hybrid human-machine data management systems
