Education

Work experience

  • Department of Information Engineering and Computer Science, University of Trento, Italy.
    • Senior/Marie Curie Fellow, Post-doctoral Researcher, 2010.5 - present
    • Founded eLifeLog.org community. 28 researchers around the world have contributed their lifelogs, collaborated for lifelog analysis, and shared the research to build an open platform for lifelogging.
    • Designed a mobile phone-based personal lifelogging App (Android) that collects and sends data to the server (PHP for server and client REST services) for the automated daily activity summarization (C++ for computer vision and Java for sensor fusion) using complex event processing (Esper).
    • Published an open source (Javascript+HTML5 for UI and Sencha Touch for mobile platform) for event-based lifelog visualization with a CEP language-based human behavior pattern composer eLifeLog Platform API.
  • VP Technologies, LLC.
    • Research Staff Member, 2009-2010.4
    • Proposed an OpenCL foreign object specification (OpenCL-FO) for multimedia abstraction and management.
  • Electrical and Computer Engineering, Georgia Institute of Technology, Atlanta, GA.
    • Research Assistant, 2002-2009
    • Development of the event-based RDAG (Relational Directed Acyclic Graph) database system to sup- port heterogeneous data streams for information chronicling purposes.
    • Implemented a relational directed acyclic graph (RDAG) server (SQL+PHP) atop RDBMS extending SQL (named EML) that supports heterogeneous data streams, unstructured queries with semantic expansion, unified object namespaces, temporal queries, rank ordering and fundamental graph operations.
    • Developed a street view traffic sign recognition method for US DOT asset management using a functional neural network and polygon-based shape decision model that effectively saved 86 percent of the manual image (3.5 TB of 50 million images covering the Louisiana, North Carolina and South Carolina states refreshed every two years) review process to identify and check the status of traffic signs on the road.
