I recently graduated from the Computer Science Department at the University of Southern California. During my
Ph.D. course, I have worked on various energy-aware computing issues in
distributed software systems running on resource-constrained heterogeneous
platforms. My dissertation, "Prediction of Energy Consumption Behavior in
Component-Based Distributed Systems", is available here. I also participated in developing
an architectural middleware platform, called Prism-MW, which supports software architecture-based development and
provides various middleware-level facilities (e.g., system deployment, dynamic
service discovery, fault tolerance, etc.) for distributed applications.
In May 2008, I joined the APEX (Advertisers and
Publishers Exchange) group at Yahoo!, which develops the next generation of
distributed online advertisement platforms running over thousands of worldwide
servers.

Systems, Software
Engineer Intern, Robert Bosch
Research and Technology Center (May 2007 - August 2007)
- Designed and implemented dynamic
software update facilities as a middleware-level service in C++, for
supporting the upgrade/removal of an existing component or addition of a
new component at runtime
- MIDAS Project (collaboration with Robert Bosch Research and Technology
Center), Software Architecture Research Group,
USC (January 2006 - present)
- Developed an architectural
middleware (Prism-MW)
in C++, which enables software architecture-based development for
distributed, pervasive, and embedded applications (e.g., sensor-based
applications)
- Designed and implemented
fault-tolerance, dynamic service discovery, priority-based event
processing, and QoS-aware deployment of software components onto their
target hosts, as middleware-level services in C++
- Energy-Awareness in Distributed Java-Based Software
Systems, Software Architecture Research Group,
USC (August 2004 - present)
- Proposed the framework for
estimating the energy consumption of a Java-based distributed software
system running on heterogeneous embedded devices, by adapting the C
source code of Kaffe JVM
- Developed the style-aware
estimation framework that facilitates the analysis of candidate
architectural styles for a given distributed software system with respect
to their energy costs at design time
- Semantic Engineering Workbench (SEW) Project, Information
Sciences Institute, USC (August 2003 - December 2003)
- Developed the integrated suites of
tools in Java, which provide an intelligent infrastructure for managing RDF
database and developing Semantic Web applications
- RDBMS-Based XML Retrieval System, Internet
Database Lab,
- Designed and implemented the XML
retrieval system in Java on top of the MySQL DBMS, which can process user
queries expressed in XML Path Language (XPath) for retrieving XML data
