Member: ACM
I am a dedicated research engineer with an interest in compilers, architectural modelling and simulation, as well as binary analysis and rewriting. My professional journey includes both academic and industrial experience in performance analysis and optimizations, code vectorization, parallel programming, software security, and RTL design. I am proficient in C, C++, Python, and ARM and RISC-V assembly, with a strong emphasis on system programming. As a maintainer of the DBM framework MAMBO, I am actively involved in open source software. I hold a BSc in Computer Science from the University of Manchester, and my PhD thesis focused on binary lifting and recompilation.
