Calculated the daily range of travel, home-to-work distance, and commuting carbon footprint for residents of Los Angeles, San Francisco, and New York. • Introduced Virtual Individual Servers, personal virtual machines owned by an individual and running in the cloud. Developed Vis-à-Vis, a privacy-preserving framework for online social networking based on VISs.
Research Staff Member
2003 - 2008		 IBM Research
Hawthorne, New York
    2005 - 2008: Research in ubiquitous computing and secure systems. • Designed and built a Trustworthy Kiosk system, in which a user leverages his mobile phone to verify the integrity of software loaded on a public computing device, prior to revealing personal information to that device. • Combined virtual machines, mandatory access controls, and hardware roots of trust to enable Trusted Virtual Data Centers with strong isolation and integrity guarantees.

    2003-2005: Research in mobile computing and software development tools. • Prototyped and evaluated SoulPad, a new mobility approach based on carrying an auto-configuring operating system and a suspended virtual machine on a pocket-sized device. SoulPad enables rapid personalization of PCs without preinstalled software or network connectivity. • Created Composite Projects, a facility for grouping and nesting programming projects in Eclipse.

Chief Technology Officer

    ShieldIP developed a novel technology for identifying and protecting digital content while preserving user privacy.

Chief Scientist
2000 - 2001		 Vindigo, Inc.
New York, New York
    Provided technical direction and prototyped technology. Devised and implemented algorithms for computing driving directions on resource-limited handheld devices. Developed walking directions software for mobile phone server. Evaluated geographic information systems, mapping data providers, and wireless data services.

    Vindigo won numerous awards as a pioneering provider of location-based services for mobile devices. Its city guides for mobile phones and PDAs gained hundreds of thousands of users within a year of launch. Vindigo was acquired by For-Side in 2004.

Principal Member of Technical Staff
1994 - 2000		 AT&T Labs and AT&T Bell Labs
Florham Park and Holmdel, New Jersey
    1998 - 2000: Research in network measurement. • Introduced MINC, a set of techniques for inferring the internal behavior of networks based on end-to-end multicast measurements. Validated MINC through MBone experiments. Enabled impromptu measurement infrastructures by standardizing MINC data collection as extensions to the Real Time Protocol. • Developed a tool for monitoring Internet multimedia traffic that parses signaling protocols at packet capture time to track dynamically assigned port numbers.

    1996 - 1998: Research in wide-area networking and wireless networking. • Built and deployed PacketScope, a system for capturing IP packets on high-speed links for unlimited periods. Used the system to gather extensive traces of public Internet traffic. Used the traces to evaluate policies for multiplexing Web traffic over flow-switched networks, and to investigate performance issues in Web proxy caching. • Led the deployment of an early wireless LAN with more than 25 access points.

    1994 - 1996: Research in mobile computing and wireless networking. Among the first to propose, design, and prototype a hierarchical handoff scheme for Mobile IP. Demonstrated its performance benefits via experiments on a wireless network. Showed that handoffs were fast and reliable enough to support interactive audio applications such as Voice over IP.

Scientist
1992 - 1994		 Matsushita Information Technology Lab
Princeton, New Jersey
    Research in mobile computing and wireless networking. • Among the first to quantify the impact of cellular handoffs on the performance of TCP via experiments on a wireless network. Devised a fast retransmission strategy for alleviating the problem and demonstrated its effectiveness, also via experiment. • Evaluated storage alternatives for mobile computers. Showed the benefits and challenges of using flash memory-based file systems for portable devices.

Post-Graduate Researcher
1987 - 1992
University of California at Berkeley and
International Computer Science Institute
Berkeley, California
    Research in wide-area networking. Built and deployed two systems for capturing IP packets. Among the first to gather raw traces of wide-area Internet traffic and use them to empirically characterize dominant TCP/IP applications. Findings contradicted widely held beliefs regarding data traffic. Used resulting models to evaluate policies and mechanisms for transporting IP traffic over ATM networks. Showed that ATM cell sizes and adaptation layers caused gross bandwidth inefficiencies for Internet traffic.
