I am a PhD Candidate in the Electrical Engineering and Computer Science Department at UC Berkeley, and am co-advised by Andy Packard and Murat Arcak. My major is Control, Intelligence and Robotics, and my minors are Computational Science Engineering and Statstics. I work in the Berkeley Center for Control and Identification (BCCI). I have two B.S. degrees in Electrical Engineering and Computer Engineering from North Carolina State University.

I am graduating this December 2012, and was an Insight Data Science Fellow in August 2012. In January, I'll be starting a full time position at Facebook.


I enable stability analysis of large-scale dynamical systems such as the Internet, airplanes and biological reaction networks. A system is unstable if control of the system is lost. The consequences of an unstable system are drastically different depending on the application: packet drops from servers on the Internet; airplane crashes; or cancerous cell mutations. Existing approaches for determining stability cannot be applied to large-scale problems due to their memory and computation requirements. I employ a divide-and-conquer approach wherein I leverage the weak coupling between subsystems and tackle each individually, which leads to smaller, more tractable computations. Unlike existing approaches, my work is amenable to implementation on a distributed system.

erinbot = erin + robot

I am an engineer because I wanted to learn how to make robots. I got this nickname and it stuck.
