Peter N Schweitzer, Ph. D.

Peter Schweitzer is a Geologist with the USGS Geology, Energy, and Minerals (GEM) Science Center in Reston, VA.


Peter works on scientific information management at the U.S. Geological Survey in Reston Virginia.  With a formal background in geology and oceanography and practical experience in software development, he serves as a bridge between the scientific research and information technology communities.

Currently his work focuses on providing usable scientific data to the public through the internet.  Perhaps best known for producing widely-used software that parses and validates geospatial metadata, I have more recently led a small team to develop controlled vocabularies and used cataloging software to design a topical index of scientific information on the web.
