Research Profile:

Dr. Ntafos's research efforts are in the areas of Program Testing, Software Reliability Estimation, Computational Geomoetry.


Role in the Embedded Software Center:

Dr. Ntafos is the lead of the Testing Group of the Embedded Software Center. Overall goal is to increase reliability by two orders of magnitude over 5 years through qualification/reuse of components, novel decomposition of system into components, derivation of system reliability from component reliability, and automated tool development/support.
