I, Youngwoo Cho, am a digital earth scientist, earth science educator, and a natural history photographer. I am currently a lecturer at Korea National University of Education. I was a postdoctoral research fellow at the Department of Geosciences, Idaho State University working for the NSF-funded Idaho EPSCoR GEM3 project. My current research interests include UAV-based remote sensing of land surface and ecology, visualization using GIS and 3D technology, and virtual geology learning.
