Professional Experience

  • 1/10-present, Consultant Software Engineer, EMC Backup Recovery Systems, Princeton, NJ.
    6/09-1/10, Senior Member Technical Staff, Data Domain, Princeton NJ.
    • Member of the CTO office of EMC BRS (previously Data Domain), researching and developing technologies for improved backup.
    • Scalable routing of content within a deduplicating backup cluster.
    • Automated content-aware assignment of backup clients to a cluster of independent deduplicating backup servers..
  • 4/02-2/09, Research Staff Member, IBM T.J.Watson Research Center, Hawthorne, NY.
    • Program codirector, System S streaming data analysis project, 1/08-2/09 (http://tinyurl.com/ibm-system-s).  Managed technical interactions between IBM and U.S. Department of Defense with respect to project planning, status, technical exchanges and other project operations.  Responsible for overall project documentation for use within IBM and Government.  On-site consultant for application of System S in classified environment. 
    • Team lead for site interoperation component of networked stream processing system., 6/05-1/08.  The CLASP system provided a framework for interoperating multiple, autonomous System S sites.  It applied techniques from grid computing, such as negotiation for shared resources, to the stream processing environment.  I was technical lead for the component (a team of four researchers full-time, collaborating with several others).  I  worked to apply this component within a classified environment.
    • Team co-lead for storage system supporting a highly scalable data streaming environment. 6/04-6/05.  I collaborated with several researchers at the IBM Almaden Research Center to design and prototype a storage system for System S.  Novel features included a “value-based retention” model, which allows different types of data to be assigned values that vary over time, and permits the storage system to delete the lowest-valued data automatically. 
    • Researcher, System S project, 3/03-.  I have participated on the project since its inception.  Early contributions include the initial evaluation of the requirements for its storage system and investigation into supporting provenance of streaming data, i.e. the relationships between data as they flow through the system.
    • Improving performance in a variety of environments, through the use of techniques to eliminate redundant data in communication and storage, 4/02-12/03.  The “Data Redundancy Avoidance Toolkit” project explored novel deduplication techniques and compared alternative techniques.  I formed the project with a colleague after performing earlier work on using similarity detection to identify files suitable for delta-encoding.  Further exploration determined that doing similarity detection on pieces of files provided substantial improvements in size reduction with lower overhead.
  • 9/98-3/02, Department Head, Distributed Systems Research, AT&T Labs - Research, Florham Park NJ.
    7/96-8/98, Principal Technical Staff Member, AT&T Labs - Research, Florham Park NJ.
    1/96-7/96 Senior Technical Staff Member, AT&T Labs - Research,
    6/94-1/96 Member of Technical Staff, AT&T Bell Laboratories.
    • Liaison between AT&T Labs--Research and the part of AT&T that offered the Intelligent Content Distribution service. Architecture, standards, project management, vendor evaluation.
    • Research areas included:
      • Internet performance, such as content distribution, web proxy caching, dynamic content generation, and delta-encoding of web pages.
      • Web applications, such as tracking changes to web pages, updating pages dynamically based on user activity, and mobile web access.
      • Adaptive techniques for disconnecting users of modem pools based on inactivity.
  • 9/96-1/97, Visiting Lecturer, Computer Science Department, Princeton University, Princeton NJ.
    • Taught distributed computing (enrollment: approximately 35 undergraduate and graduate students). Advised two-person undergraduate independent project building a Java-based FTP client.
  • 10/91-6/94, Scientist, Matsushita Information Technology Laboratory, Princeton NJ.
    • Researched system support for mobile computing, and especially storage systems for mobile computers. Investigated memory-based file systems using DRAM and flash memory.
    • Investigated methods to reduce power consumption of magnetic disks using on-line and off-line heuristics, and using flash memory.
    • Built and evaluated mechanism to integrate compression and virtual memory, to improve paging performance on machines with limited memory.
  • 10/90-9/91, Visiting Professor, Vrije Universiteit, Amsterdam.
    • Redesigned and implemented process management and virtual memory in the Amoeba system. Investigated the usefulness and feasibility of client file caching in a message-based environment. Compared Amoeba with the Sprite network operating system in order to evaluate kernel architectures, resource allocation models, and communication protocols.
    • Taught seminar on distributed systems (enrollment: approximately 30 students).
  • 5/86-9/90, Designing and Implementing Transparent Process Migration, U.C. Berkeley.
    • Evaluated tradeoffs between transparency, performance, reliability, and simplicity in a process migration facility, which permits processes to move transparently during execution and to execute independently of their location. Allowed idle workstations to be used for parallel compilations and other processor-intensive applications, while respecting the autonomy of individual workstations. Investigated alternative methods for managing access to idle hosts. Examined design decisions in the context of practical experience in a community of 20-30 users over a period of over a year.
  • 10/84-9/90, Implementing Sprite, U.C. Berkeley.
    • Implemented the Sprite network operating system with other graduate students. In addition to process migration, my contributions included much of the original low-level kernel scheduling, synchronization, and process management code; a UNIX compatibility library to permit porting of UNIX source programs to Sprite; and support for many user-level programs such as emacs and TeX.
  • 9/87-6/89, Investigating High-Performance File Systems, U.C. Berkeley.
    • Worked on the preliminary design of a log-structured file system, which would provide high performance by reducing the disk seeks necessary to write small files in arbitrary locations on a disk. Instrumented Silicon Graphics workstations to trace file system operations for the purpose of trace-driven analysis of file system performance.
  • Summer 1987, Building an Archive Facility for Optical Disks, Digital Western Research Laboratory.
    • Built a network-wide archive facility for use with write-once optical disks. Users on any host could archive a directory hierarchy and retrieve the archive using a unique identifier.
  • 1/86-5/86, Teaching Assistant, U.C. Berkeley.
    • Assisted in teaching the undergraduate operating systems course, working with Professor John Ousterhout.
