I'm a research staff member at IBM T.J. Watson Research Center in Yorktown Heights, NY. Before coming
to NCSU I received my Master's degree in Computer Science from Stony
Brook University in May of 2009. I then worked in Charleston, SC for a
year and a half before deciding I wanted to pursue a Ph.D. After starting my Ph.D. I was a research intern at NEC Labs in Princeton, NJ in the summer of 2012. Similarly, in the summer of 2013, I was a research intern at IBM T.J. Watson Research Center in Yorktown Heights, NY. I had a great time at both locations and highly recommend doing a industry based research internship to any aspiring PhD students reading this!
Ourside of work, I enjoy playing music, spending time with friends, cooking/eating food. To me, there's nothing better than coming inside from being out in the cold and smelling something that's been simmering to perfection all day.
My research interests include big data analytics, debugging, distributed systems, and virtualized environments. Most recently, I have worked on the developing fine-grained diagnostic tools for virtualized cloud environments.
My PhD advisor was Prof. Xiaohui (Helen) Gu
and I was a member of the Distributed System Research Group on Autonomy, ResilieNce, Collaboration, and Energy (DANCE
) from May 2011 until my graduation in June 2015.
