RESEARCH EXPERIENCE

I worked on many layers of Grid and Web Services: from high level (adaptive orchestration of services) to low level (performance of XML parsers). Selected projects:

• Workflows in Grids and Scientific Computing: I am investigating the applicability of business and Web Services based workflows for Grid computing.

  • Grid Process Execution Language (GPEL): My dissertation work is focused on the design of a workflow language and runtime system for dynamically-adaptive and long running Grid workflows. Our goal is to provide a workflow system that can be used for Linked Environments for Atmospheric Discovery (LEAD) National Science Foundation Large Information Technology Research (ITR) project that is creating an integrated, scalable cyberinfrastructure for mesoscale meteorology research and education (overview of the system architecture). I presented my initial findings at the GGF10 meeting of the GGF Workflow Management Research Group and design rationale can be found in Adapting BPEL to Scientific Workflows paper.
  • Adapting BPEL4WS to OGSI Grids: I investigated how BPEL4WS (Business Process Execution Language for Web Services) can be adapted for use in OGSI and WSRF based Grids and presented a research paper based on my findings in the GGF10 Workflow Workshop.

• Performance and Best Practices for Grid and Web Services: I am looking into how Grid and Web Services should be used to take full advantage of their capabilities:

  • Performance of Web Services: I worked extensively on identifying key performance bottlenecks in the design and implementation of SOAP toolkits, and other issues such as evaluating of security overhead in Web services, authorization framework, streaming validation of SOAP digital signatures, and design of binary XML for scientific application.
  • JSR 173 (Streaming API for XML - StAX) and JSR 280 (StAX in J2ME): I participated in the JSR 173 expert group and used my experience with XML pull parsing tools to shape the StAX specification and I am now participating in JSR 280 expert group. Its goals includes the definition of a subset of StAX suitable for J2ME.
  • XPP - designed and implemented XML Pull Parser (XPP) API. The API is designed for high performance streaming applications that require a small and fast XML pull parser and it is especially well suited for unmarshalling complex recursive data structures from XML (such as SOAP). Successfully delivered three generations of pull parsers: XPP1, XPP2, XPP3/MXP1
  • XML Pull Parsing: I was part of the two-member team that designed and developed an Common API for XML pull parsing using the "pull" model (and I maintain the website about XML Pull Parsing). I wrote a comparison push and pull approaches to XML parsing, including researching their applicability to Web Services.

• Web Services Middleware and Modular and Extensible XML Web Services Stack:

  • I designed and implemented a Web Services XML Utility Library (WS/XSUL). It is a highly modular library that provides a framework for XML based processing including support for doc-literal, request-response and one-way messaging, modules for a lightweight XML/HTTP invoker and processor, SOAP 1.1/1.2 support, digital signatures, WSDL and dynamic invocations (including an extended implementation of WSIF.) In particular WS-Dispatcher allows internal services to be safely exposed to Internet and allows clients that do not have endpoints to become true WS peers and supports intermittently connected clients that may be moving between networks and WS-MsgBox provides a service which is similar to P.O. Mail Boxes but works for Web Services that uses WS-Addressing. and allows clients that do not have endpoints such as clients situated behind firewall or running as applets inside browser to use message box address as their address. Motivation and design is described in Asynchronous Peer-to-PeerWeb Services and Firewalls paper.
  • Apache Web Services Invocation Framework 2.0 (WSIF):I was a member of the original team in IBM that designed WSIF and I implemented the first version of WSIF. The implementation was then donated to Apache. I was the release manager for the first official Apache WSIF release of WSIF.
  • I participated in design of AXIS2: in particular sharing my experience with high performance XML streaming, use of pull parsing and design of XML object model (AXIOM).
  • WS-Messenger - WS-Notification and WS-Eventing Implementation: I developed in one of the first implementations of WSRF and WS-Notification specifications and tested its interoperability with other implementations during an WSRF/WS-Notification Interop Workshop (the results are published online). Then I helped to take this prototype and to develop it into a WS-Messenger - an unique messaging middleware that supports both WS-Eventing and WS-Notifications in one system. I helped also to integrate the Narada Brokering notification system with WS-Messenger.
  • Grids and Components: I am a member of the team that worked on the design and development of applications based on the Common Component Architecture (CCA) specification. I co-authored a research paper on the mapping between the CCA and the Open Grid Services Infrastructure (OGSI) specification.
  • Older projects: SoapRMI and XSOAP - SoapRMI is a high performance implementation the SOAP protocol that has API similar to Java's Remote Method Invocation (RMI) API. The final version of this toolkit - XSOAP - has a layered implementation with complete support for SOAP 1.1 Section 5; Security in XSOAP: I designed and developed authentication and authorization capabilities for the XSOAP toolkit based on the Grid Security Infrastructure (GSI) and Java CoG; Co-developed Xydra - web service that provides flexible XHTML template based WSDL invoker; Worked on the design and development of the KnownSpace - a free, portable, and open-source data management system built in Java where I developed the 'Engine' that allowed to execute search queries and to cluster related entities using the LSI algorithm and later helped with design of Fluency - an user interface builder that aims to give power of UI programming to non-programmers; XMessages and XEvents are publish-subscribe libraries for messaging and events designed for Web Services before WS-Eventing and WS-Notification were created; XSpaces: an implementation of XML based tuple space called XSpaces that would be used together with XMessages to provide highly decoupled and flexible communication mechanism for applications; XML Pull Parser in C++ - version of XPP1 in C++; ...
