Cristian Lumezanu Research Staff Member NEC Labs lume la nec-labs punct com CV | Publications | Research |
I am a researcher at NEC Laboratories America in Princeton, NJ. Previously, I was a postdoctoral researcher in Nick Feamster's group at GeorgiaTech. I hold PhD and MS in Computer Science from the University of Maryland, where I worked with Neil Spring and Bobby Bhattacharjee. I come from Craiova, Romania.
My research spans the areas of networking, distributed systems, and security, with emphasis on building and measuring network systems that tolerate misbehavior, abuse and failures.
