Work

  • 2025.05 - Present

    Cambidge, UK

    Technical Expert
    Huawei Labs
    I will join Huawei Labs to lead the ondevice team.
  • 2019.01 - 2025.01

    Cambidge, UK

    Senior Researcher
    Samsung AI Centre (SAIC), Cambridge
    I was leading research on reasoning and neurosymbolic learning within SAIC-Cambridge.
    • I developed provably correct techniques that scaled logical reasoning to billions of facts and led to deep models with substantially higher accuracy.
    • I was the first to prove that we can learn neural classifiers using logical theories as the source of supervision, characterizing also learning imbalances in neurosymbolic learning.
    • I developed CPU-based techniques capable of scaling rule mining to millions of facts, taking less than 1% of the run time needed by the state-of-the-art GPU-based approaches.
    • I was the first to show how to efficiently answer queries in second-order logical theories that include millions of facts, while preserving the correctness and completeness of the answers.
  • 2016.10 - 2018.12

    London, UK

    Research Fellow
    Turing Institute, UK
    My research focused on accessing heterogeneous data under privacy restrictions and logical reasoning both from an applied and a theoretical perspective.
    • I was the principal investigator of a project on accessing distributed NHS data under formal privacy guarantees, receiving funding from the Turing and the FARR institutes.
    • I developed provably correct techniques for accessing remote data under formal privacy guarantees.
    • I developed the first technique for efficiently answering queries over Web-scale knowledge graphs under complex logical theories, offerring guarantees on the correctness and completeness of the answers.
  • 2013.06 - 2016.09

    Oxford, UK

    Research associate
    Department of Computer Science, University of Oxford, UK
    • I theoretically established whether and how to answer queries subject to access restrictions and data constraints under guarantees on the completeness of the answers.
    • I led a project on accessing data from the European Bioinformatics Institute (EBI), the National Centre for Biotechnology Information (NCBI), and the Kyoto Encyclopaedia of Genes and Genomes (KEGG), being awarded an EPSRC IAA grant.
