Research

Currently I am interested in Computer Architecture and Security. My research interests focus on exploring the design space of spectre attack and mitigations and model the information leakage through speculative execution, but I am also interested in cache side-channels, prefetchers, predictors, efficient address translation and any idea towards more safe, energy-efficient and powerful architectures.
