Curriculum Vitae

Dr. Schulze is a soil scientist whose research and teaching interests span various aspects of soil science including pedology, digital soil mapping, soil mineralogy, soil chemistry, and international agriculture. He teaches a field-based course titled, Soils and Landscapes, for which he developed an innovative teaching with maps approach that is used in various courses at Purdue and elsewhere. He is also currently part of a team co-teaching Introductory Soil Science. He leads the development of Soil Explorer, a soil data visualization platform that is available as an app for iPhone/iPad and Android devices and as a website (SoilExplorer.net). He has conducted research internationally in Germany, Italy, Kenya, Uganda, Brazil, and Peru, and is currently a co-PI on the Soil Health and Environmental Vulnerability Assessment project that is part of the Arequipa Nexus Institute, a collaboration between Purdue University and the Universidad Nacional de San Agustín (UNSA) in Arequipa, Peru. He has advised 14 PhD and 5 MS students, and 3 postdocs and has hosted 4 long term (6-12 mo.) and 3 short term (1-3 mo.) visiting scholars.
