Bachir is a Doctoral Student in the Software Reliability Group at Imperial College London. He completed his MSc. in Computer Science from Saarland University. He joined the group after working at CISPA.
His research is focused on advancing software security and reliability through innovative fuzz testing techniques and input generation methods. His work explores grammar-based and mutation-based fuzzing to uncover vulnerabilities in input parsers and complex systems. He has developed tools like Gmutator, G+M, and AFLRepair to enhance the generation of edge-case and diverse test cases, bridging gaps between input specifications and parser implementations. He is passionate about creating scalable solutions that drive more robust and secure software systems.
