Dalia E Varanka, Ph.D.
Dr. Varanka leads the Geospatial Semantics and Ontology project of the Center of Excellence for Geospatial Information Science.
Dalia Varanka is a Research Geographer with the U.S. Geological Survey.
Dr. Varanka 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.
Dr. Varanka 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. She started her Federal career at the U.S. Bureau of Land Management in 1993 and joined the USGS in 1997. Dr. Varanka has been a Research Grade Evaluation (RGE) scientist since 1998 with the National Geospatial Program.
Member, Cartography and Geographic Information Society (CaGIS)
Dr. Varanka teaches a Geospatial Ontology and Semantics course for the Geographic Information Systems degree for the Johns Hopkins University Advanced Academic Programs.
