Before joining Pitt, I was a research scientist in the PitLab at Virginia Tech where I worked on the development of semantic Web technologies that were part of the NASA-funded Semantically Enabled Scientific Data Integration (SESDI) project. A demo that included my work recently won the best demo award in the 7th International Semantic Web Conference (ICWS), Karlsruhe, Germany, October 26-30, 2008. As a PitLab member, I also was significantly involved in the multi-million NSF GEON project.

In my PhD work, I developed mRACER, a routing protocol suite based on a novel service-oriented architecture for sensor-actuator networks where nodes expose their capabilities to applications as application-independent services. I implemented mRACER on top of TinyOS and conducted several experiments that confirmed m
RACER's ability with regard to each of its design objectives, namely, energy efficiency, scalability, end-to-end reliability, and support for QoS.
