WORK EXPERIENCE

• Multimedia Workload Characterization, Broadband Information Systems Lab, HP Labs. Developed video workload models and QoS metrics obtained by empirical studies of video-on-demand systems. Developed analytical models of video QoS parameter interrelationships. Proposed a unified metric that incorporates response and resource characteristics corresponding to the user and service provider. Investigated economic models for interactive QoS for multimedia systems.
• Distributed Multimedia Servers, Broadband Information Systems Lab, HP Labs.
• Involved in design and implementation of distributed video servers, resource management (load-balancing, data placement, request assignment, high availability) for distributed media servers.
• Worked on broadband networking for multimedia including protocols like ATM, MPEG, IP and implemented device drivers for real-time operating systems.
• Provided support for scheduling real-time multimedia tasks and multimedia networking protocols using real-time operating systems.
• Worked on distributed systems stability techniques with specific applications to multimedia.
• Investigated resource management techniques for distributed Web servers.
• Digital Choreography and Virtual Environments, HP Labs. Recipient of a Grass Roots Basic Research Grant to pursue an investigation in digital dance and choreography. Established a working relationship with the Media Research Lab at New York University. Worked on interactive animation and multimedia systems for applications in the digital studio market - a prototype interactive animation system from NYU was extended to support digital choreography and conduct studies on motion manipulation in distributed environments.
• Object Oriented Database Management, Cooperative Computing Systems Lab, HP.
• Involved in the design and implementation of memory management schemes, interoperability facilities, authorization mechanisms and other technical aspects in a commercial object oriented database - OpenODB/Odapter.
• Provided consultation and prototyping software for oil and gas applications on object oriented databases.
• Worked on performance and benchmarking of object oriented databases.
• Compilers for Parallel Architectures, IBM T.J. Watson Research Center. Worked with the Hybrid Dataflow Architecture Group on compilation techniques for parallel machines - abstract intermediate forms, representing and executing sequential and dataflow computation on a custom high performance architecture.
