Experience

Defense Mapping Agency 1993-present

Scientific advisor for data base efforts at the Defense Mapping Agency, working on issues associated with populating and maintaining large, diverse, stores of geospatial data, along with associated metadata, and operational data (e.g., planning, cost records). Working with DMA product experts to define a limited set of "data components" from which a much wider variety of mission-specific products can be generated than DMA currently supports and to define an environment where extant feature data (both integrated data sets and opportunistic collections of features) can be readily evaluated, imported, upgraded (for accuracy, currency, completeness, attribution, or density), recorded and tracked. Leading efforts to define a conceptual model of metadata to be used across production and dissemination systems for multiple data types and sources. Defining data flows and interfaces for a new, open, production infrastructure that supports both greater operational flexibility and improved production efficiency over current systems.

SAIC, MAXIM Technologies 1986- 1993

Led systems engineering, integration and development activities on

* Client-server systems for document storage and retrieval incorporating both image and full-text search, along with image scanning and optical character recognition capabilities

* System engineering for large (millions of documents, terabytes of text data) multi-media document dissemination and storage system

* Exploratory efforts to provide effective tools for professional current-affairs analysts, e.g., full text search and retrieval; office automation; multi-lingual data bases; machine translation

Technology Service Corporation 1981-1986

Led the Washington office supporting the mapping and intelligence communities. Provided technical leadership for system engineering projects addressing first end-to-end digital mapping system developed for DMA, including development of a common set of feature and attribute definitions for describing a diverse collection of mapping products.

Education: Ph. D., M.A., University of Texas. A. B., Ohio University.
