Dalia E Varanka, Ph.D.

Dr. Varanka leads the Geospatial Semantics and Ontology project of the Center of Excellence for Geospatial Information Science.

Biography

Dalia Varanka is a Research Geographer with the U.S. Geological Survey.

 

Education

She received her BA degree from the University of Wisconsin-Green Bay in Urban and Regional Analysis (1978) and her M.A. degree in Urban Environmental Geography at the University of Illinois at Chicago (1987). Dr. Varanka’s Ph.D. degree in Geography from the University of Wisconsin-Milwaukee (1994) focused on the spatial information theory and cartography and society.

 

Professional Experience

She worked full-time through graduate school, first as a research assistant at The Field Museum of Natural History and later The Newberry Library in Chicago.

 

Affiliations

Dr. Varanka began her Federal career in 1993 as a Physical Science Technician with the U.S. Bureau of Land Management. She joined the USGS in 1997 and has been a Research Grade Evaluation (RGE) scientist since 1999 with the National Geospatial Program.

 

Non-USGS Partners

Dr. Varanka teaches a Geospatial Ontology and Semantics course for the Geographic Information Systems degree for the Johns Hopkins University Advanced Academic Programs.
