John Hessler

John W. Hessler is a Specialist in Computational Geography and Geographic Information Science at the Library of Congress.

A Fellow of the Royal Geographical Society, he is the founder of the Game Theory Lab for the Study Games, Virtual Reality, and Computation, and is a Lecturer in the Graduate School of Advanced Studies at Johns Hopkins University. Teaching at the interface of game theory, computation and neuroscience, he has taught seminars in advanced spatial analysis, the foundations of quantum computing, computational quantum field theory, the mathematics of brain mapping, and on artificial and biological neural networks.

His current research focuses on the use of renormalization group methods, derived from Quantum Field Theory, to study the mysterious mathematics and function of deep neural networks. He is also interested in the theory of Markov Chains and their application to spatial distribution, mapping and Gerrymandering problems, and in the application of algebraic topology in the mapping of biological, artificial, and virtual neural networks.

He is the author of more than one hundred books and articles, including MAP: Exploring the World; The Naming of America: Martin Waldseemüller’s 1507 World Map and the Cosmographiae Introductio; A Renaissance Globemaker’s Toolbox: Johannes Schöner and the Revolution of Modern Science, 1475–1550; Seeing the World Anew: The Radical Vision of Martin Waldseemüller’s 1507 and 1516 World Maps. His work has been featured in many national media outlets including the New York Times, Washington Post, Discover Magazine, the Atlantic’s CITYLAB, the BBC, CBS News and most recently on NPR’s “All Things Considered” and in WIRED. An avid mountaineer, he is also an occasional contributor to Alpinist Magazine.
