/ Research

I work in the HLC Lab at Sapienza, within the Net4Exa project. Most of my time goes into CRAB, a benchmarking framework for HPC systems that started as my bachelor's thesis — a ground-up redesign of an older tool — and now runs on Leonardo, one of the EuroHPC pre-exascale machines.

/ Security

The other half is low-level security: binary exploitation and reverse engineering. Stack smashing past canaries and ASLR for coursework, heap exploitation for a CTF, IDA for hobby disassembly. Next on the list: playing CTFs properly — pwn and rev, solo for now.
