As Associate Director of Geovisualization, Helena plays a strategic leadership role in the Center’s overall research agenda as well as geovisualization specific research using Tangible Landscape.  Helena is a Center Faculty Fellow, a Professor in the Department of Marine, Earth and Atmospheric Sciences, and a member of the Geospatial Science and Technology Faculty at NC State. Her research uses tangible geospatial modeling environments, dynamic simulations of landscape processes, and analysis of LiDAR time series data to investigate coastal evolution, soil erosion control, and sustainable land management. Helena is a member of the OSGeo Foundation and the Open Source GRASS GIS Project Steering Committee and a co-author of the first book on Open Source GRASS GIS. Helena has developed graduate courses based on Free and Open Source Geospatial Software, including the Geospatial Modeling and Analysis course and an advanced special topics course on Multidimensional Geospatial Modeling.
