Completed Projects:


I spend my time understanding hard computational challenges and designing simple and scalable solutions towards these challenges. I published mostly in the areas of database systems, AI, and theoretical computer science. Here is a list of my current research projects:

  • Factorised databases: FDB (data compression; query processing with low complexity); F (distributed & parallel machine learning over databases); F-IVM (incremental maintenance of machine learning models and database queries)
  • Probabilistic databases: SPROUT (probabilistic query processing, lifted inference); MayBMS (probabilistic data models, probabilistic query languages); ENFrame (probabilistic programming); Pigora (probabilistic data integration)
  • Datalog engines: With folks@LogicBlox on their database engine, their meta-engine, and a probabilistic extension of Datalog; with Oxford colleagues on RDFox.

Past projects to which I contributed as student/co-investigator/principal investigator:

  • DIQOPT: Distributed Query Optimisation
  • G-Store: A Storage Manager for Graph Data
  • SKAR-DB: Managing Square-Kilometer-Array Data
  • SPEX: Streamed and Progressive Evaluation of XPath
  • Agora: Living with XML and Relational Data

Current research support: Google; EPSRC (DBOnto, Industrial PhD CASE, VADA); ERC Consolidator Grant (FADAMS); Fondation Wiener Anspach; Microsoft Azure; Ordnance Survey.

Past research support: Amazon Cloud; Cornell; EPSRC (PROQAW, ADEPT); EU FP7 (FOX, HiperDNO); LogicBlox; Oxford (Astor Travel Fund, Lockey Fund).

PhD and postdoc positions available in my group funded by a 5-year ERC consolidator grant! Please contact me if interested.
