A.J. Rohn

A.J. is a recent graduate of the Geography and Environmental Studies programs at the University of Wisconsin-Madison with a passion for writing and interests in areas ranging from ecology to geosophy to geopolitics. He enjoys the geography of Wisconsin, be it the north woods or city life in Madison. He loves to read research papers in geography, books by scholars like Yi-Fu Tuan and Bill Cronon (both at UW-Madison), as well as classic fiction writers like Thomas Pynchon and Fyodor Dostoevsky. He is very much inspired by the work of all the people he encountered in Madison’s geography department, so expect a wide range of topics when reading his articles here.
