About Me

I am now a Computer Scientist at the USC Information Sciences Institute, Computational Systems and Technology division in Arlington, VA!

I completed my Ph.D. in Computer Science in June 2018 under Hank Hoffmann as a member of the Systems Group and the Self-aware Computing project. Read about some of our group's work on Crunchbase News. Prior to attending graduate school, I worked for five years in industry as a software engineer.

My graduate research addresses managing performance and power/energy in complex systems using feedback control, machine learning, and optimization techniques. I'm interested in developing abstractions for integrating resource management solutions with modern software designs. My work impacts systems ranging from embedded real-time to large-scale distributed, High Performance Computing, and cloud architectures.

Work Experience

Research Intern at Lawrence Berkeley National Laboratory

June 2017 - September 2017

At the Computational Research Division, continued work on power/energy awareness in High Performance Computing (HPC). Primarily focused on my dissertation research on maximizing energy efficiency in HPC systems. Other power/energy-related projects were also explored.

Research Assistant at Mozilla Corporation

June 2015 - September 2015

At Mozilla Research, instrumented the experimental Servo web browser at a fine-grained level to better understand the timing and energy behavior of its components and workloads. Servo is targeted for mobile devices, multi-core systems, and high-performance GPUs. Future work is to apply power/energy saving techniques. Read more about the work here.

Software Engineer Sr. at Lockheed Martin Corp.

August 2008 - August 2013

Extensive experience with software design, implementation, and testing for both fielded systems and research projects. Work included regular interaction with customers, contractors, foreign representatives, and uniformed personnel. Additionally, it involved domestic and international travel for test events, military exercises, conferences, support, and demonstrations.
