As a computer architect, I broadly want to enable the continuing exponential growth in computing capability despite the slowing of Moore’s Law. My research interests are heterogeneous systems, memory systems, and hardware-software interaction.
Online book aimed to familiarize new users with the gem5 architectural simulator. This is a current work-in-progress, so check back often for updates.

Math Teaching Assistant in Georgia Tech Math DepartmentFall 2007
Taught Honors Calculus I to class of 32 twice weekly and assisted students one-on-one.
Intern at Advanced Micro Devices (AMD) ResearchSpring 2012
Explored new cache coherence architectures to support future heterogeneous CPU-GPU processors. The publication Heterogeneous System Coherence for Integrated CPU-GPU Systems (HSC) is a result of this work.
Applied for patent "Serving memory requests in cache coherent heterogeneous systems" that describes an optmization to HSC for producer-consumer sharing on heterogeneous systems.
Co-op at Georgia Tech Research Institute (GTRI)2008–2009
Built large Windows software application as part of a team to monitor subsystems in modern fighter jets and developed software for embedded machines running VxWorks which controlled electronic warfare systems.
Acquired Secret Security Clearance
