Research Scientist

Intel Labs

Jun 2012 – Present Oregon
I define and evaluate innovative security architectures for mitigating exploits and malware. I draw on my expertise in architecture, compilers, operating systems, virtualization, HW/SW co-design, and formal methods to effectively devise solutions that are well-adapted to workload requirements.
