Current Research Interests

My research interests include computer architecture and compilers targeting future generations of high-performance and low-power multi- and many-core systems. Areas of focus include: high-performance memory systems, retargetable dynamic binary translation and system virtualization, parallel program debugging and testing, and parallel simulation techniques for many-core systems.
