I am a computer science Ph.D. student at Columbia University working under Dr. Roxana Geambasu. I'm broadly interested in operating systems, distributed systems, security and privacy. I am supported by a Google Ph.D. Fellowship.

Google, Mountain View, CA (May 2014 - August 2014)
I worked as a software engineering intern on the Android platform security team to improve system access control. I moved much of the ad hoc access control into centralized and auditable SELinux Policy. Some of my contributions to AOSP were included in Lollipop.
Oak Ridge National Laboratory, Oak Ridge, TN (June 2011 - August 2011, May 2012 - December 2012)
I worked in the Cyberspace Science and Information Intelligence Research Group (CSIIR) with Erik Ferragut and John Goodall. I built distributed systems applications for log analysis and data analytics using the Storm framework and NodeJS. I also worked on a system call based anomaly detection system.
Auburn University, Auburn, AL (February 2011 - May 2012)
At Auburn I worked under Dr. Xiao Qin and Dr. Orlando Acevedo Under Dr. Acevedo I built a framework for molecular dynamics simulation framework parallelized using NVIDIA's CUDA architecture. In Dr. Qin's lab I worked on writing projects for a future Hadoop based distributed systems class.
