2014: Keith Winstein (Transport Architectures for an Evolving Internet)

  • Winstein's dissertation proposes and develops the idea of computer-generated congestion control, creatively solving both classical and new problems in network resource management.
  • With Honorable Mention
    • Hongqiang Liu - (Traffic Planning under Network Dynamics)
      Liu's dissertation presents the design and implementation of practical, uniform, automatic, and proactive techniques to prevent the link
      congestion commonly caused by network faults and maintenance.

The committee: Mark Crovella, Arvind Krishnamurthy, Nikolaos Laoutaris, Alan Mislove, Neil Spring,  Arun Venkataramani


2013: Aaron Schulman (Observing and Improving the Reliability of Internet Last-Mile Links)

  • The dissertation provides the first observations of fundamental factors that limit the reliability of the Internet’s critical last-mile infrastructure and presents improvements to mitigate the effects of these factors.

2012: Shyamnath Gollakota

  • The dissertation provides a fundamentally new and practical way to deal with interference in the wireless medium, often rendering it harmless or even turning it into an advantage. While traditional wireless systems have attempted to avoid interference, this thesis is the first to practically demonstrate techniques to decode packets under significant interference and leveraging it for improved security. The thesis is transformative and can significantly impact the design of future wireless communication systems.
  • Runners Up:
    Ashok Anand
    The dissertation presents a range of innovative techniques to eliminate redundancies in traffic across diverse hosts, routers, and networks across the Internet. The work itself is rigorous and comprehensive in its treatment of redundancy elimination techniques. As the demand for Internet bandwidth continues to be higher than ever before, such approaches can prove to be highly beneficial.
    Laurent Vanbever
    The dissertation provides fundamental innovations that allow a network to be re-configured without causing inconsistencies in network routing structures. The thesis encompasses good theoretical concepts that ensure global correctness properties and practical manifestations of these concepts to make them deployable. As networks around us continue to get more complex, the techniques developed in this thesis provide significant tools to improve efficient management of these networks.

2011: Minlan Yu, Scalable Management of Enterprise and Data-Center Networks

  • Minlan Yu’s PhD thesis concerns the design, implementation and evaluation of a scalable management architecture for enterprise and data center networks.  Minlan’s research goes full circle, from important practical problems, to creative data structures and algorithms, to rigorous analysis and modeling, and finally to the design and implementation of novel systems.  Minlan’s thesis is exceptional both in breadth and depth, with proven results on one of the world’s largest datacenters.
    Runners Up:
    Michel Piatek, Scalable Data Sharing Without Centralized Trust
    Michael Piatek’s PhD thesis concerns the design and construction of effective content distribution systems. Amongst other contributions, he uses a mix of clever analysis and experimentation to devise a new peer-to-peer system “BitTyrant” that greatly outperformed alternatives, and which has been downloaded more than a million times. Michael’s dissertation succeeds by delivering insightful theory, demonstrated in practice.
    Aruna Balasubramanian, Architecting Protocols to Enable Mobile Applications in Diverse Wireless Networks
    Aruna Balasubramanian's PhD thesis concerns enhancing the experience of mobile users in the face of challenging network conditions, for
    instance by building disruption-tolerant networks.  Her work is based on careful analysis, and has been deployed and tested out in the field.  Her work has been cited hundreds of times, and has had a large impact on research in the area, raising the bar for experimental verification of wireless network systems.
