Research Scientist Citrix Online Brighton, MA Email: krishna.ramachandran@citrix.com Ph.D. in Computer Science, University of California, Santa Barbara, 2007 M.S. in Computer Science, University of California, Santa Barbara, 2003 B.E. in Computer Engineering, Pune University, India, 2000 Research InterestsI am interested in overlay networking, routing protocols, VoIP, and anything to do with wireless systems.At Citrix Online, I help build scalable network services that can support Internet-scale, real-time collaboration. My PhD dissertation title is "Design, Deployment, and Management of High-capacity Large-scale Wireless Networks". My dissertation offers a network architecture for high-capacity, multi-radio, multi-channel wireless mesh networks. This architecture incorporates solutions for high-throughput routing, interference-aware channel assignment, mobility management, network monitoring, and network management. The UCSB MeshNet is a prototype mesh network constructed using this architecture. PublicationsSome of my representative publications are given below. See here for a full list.K. Ramachandran, S.
