Compilers, operating systems, and runtimes exist precisely so you can forget about page tables, cache lines, and instruction pipelines while you get work done. Attackers, and the researchers trying to stay ahead of them, don&rsquo;t get that luxury. Every exploit involving memory corruption, firmware, or a leaky microarchitectural feature lives exactly at that seam between the code you wrote and the silicon actually running it. This research examines that seam systematically, aiming to produce techniques reproducible enough to be useful, rigorous enough to be academically sound, and constrained enough to stay ethically defensible.</p>
