Max Lu, Kansas State University

Max Lu has been involved in AP® Human Geography for almost 20 years. He went to his first reading in 2003, the third year after the AP® Human Geography course was created. Since then he has gone to the reading almost every year, filling roles as a reader, table reader, and question leader. From 2007 to 2015, Max served on the College Board’s AP® Human Geography Test Development Committee and was co-chair for the final three years of his service. As a College Board-certified consultant, he has taught AP® Human Geography workshops and summer institutes around the country since 2007. Max received his BS and Master’s degrees in China and his doctoral degree from Indiana University. He is currently a professor in the Department of Geography and Geospatial Sciences at Kansas State University. His research has dealt with such topics as population migration, rural population change, regional inequality, and the geography of methamphetamine labs. An interesting fact about his life as a geographer is that in the last 30 plus years, Max has lived at about 40°N in latitude in three different places: 6 years in Beijing, 6 years in Bloomington, Indiana, and then Manhattan, Kansas where he currently lives and teaches!

He earned his Ph.D. at the University of California, Berkeley. He studies the complex interactions of culture and nature through a specific focus on national parks and natural resources. In his research, he combines the analytical tools of cultural and political ecology with landscape studies. He has pursued these investigations through historical and ethnographic research mostly in East Africa, with some comparative work in North America and Central America. His current research explores interwoven narratives of nature, landscape, and identity in the European Union, with a particular emphasis on Spain. His scholarly books include Imposing Wilderness: Struggles over Livelihoods and Nature Preservation in Africa (1998), Making Political Ecology (2005), and The Commercialization of Non-Timber Forest Products (2000), the latter co-authored with Eric Hirsch.
