John Hessler

When not climbing in the Alps or mountain biking through some jungle, John W. Hessler is a Lecturer in Quantum Theory and Computing in the Graduate School of Advanced Studies of the Krieger School of Arts and Sciences at the Johns Hopkins University and a Specialist in Computational Geography & Geographic Information Science at the Library of Congress in Washington, DC. Hessler's main line of research focuses on the ontological and mathematical foundations of spatial computing and Geographic Information Systems. He has written on genetic and evolutionary algorithm design and on the philosophical foundations and use of neural networks and deep learning in geographic research. Hessler has taught classes and seminars on the foundations of quantum theory and computing, human brain mapping, the mathematics of neural computation and on the computational complexity of the Gerrymandering problem, where he has developed new Markov Chain methods. The author of more than one hundred books and articles, including the New York Times best-seller, MAP: Exploring the World, his work has been featured in many national media outlets including the New York Times, Washington Post, Discover Magazine, WIRED, the Atlantic’s CITYLAB, the BBC, CBS News and most recently on NPR’s All Things Considered.
