I am a Lecturer (Assistant Professor) at UCL Computer Science, a member of Software Systems Engineering and CREST. I received a PhD from the National University of Singapore, and a Specialist Diploma from Saint Petersburg State University. My research focuses on automated program repair. Among other things, I developed Angelix program repair system, founded program-repair.org, and received ACM SIGSOFT Outstanding Doctoral Dissertation Award in 2019 and ACM SIGSOFT Distinguished Paper Award in 2023.

Projects

  • Semantic Program Repair
    2013–Present
    The goal of this project is to develop a practical automated program repair system that uses semantic analysis to understands the meaning of code and is able to correctly fix complex software bugs.
  • Modus
    2022–Present
    A language for building Docker/OCI container images that uses logic programming to express interactions among build parameters, specify complex build workflows, automatically parallelise and cache builds, help to reduce image size, and simplify maintenance.
