Bachir is a Doctoral Student in the Software Reliability Group at Imperial College London. He holds an M.Sc. in Computer Science from Saarland University and previously worked at CISPA.
His research focuses on software security and reliability, particularly fuzz testing and automated input generation. He develops techniques and tools that improve software testing by generating diverse inputs to uncover vulnerabilities and strengthen the robustness of complex systems. His work includes Gmutator and RepairFuzz.
Bachir is a recipient of the Google PhD Fellowship in Software Engineering and Programming Languages.
