Associate Research Scientist
University of Maryland, Baltimore County
I am an Associate Research Scientist at the Goddard Planetary Heliophysics Institute (GPHI). GPHI, part of the University of Maryland, Baltimore County, is a cooperative research agreement between the university and NASA's Goddard Space Flight Center. My research interests are in the semantic web (particularly provenance) and software agents. I'm involved in several projects investigating the application of these technologies within the Earth and space sciences.
