- 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.
- Pervasive Computing Solutions, IBM T.J. Watson Research Center,
