Over the past decade or so, the digital footprints left by us, specifically in terms of social networking, mobile phone, and GPS use has led to tremendous advancements in understanding the movement patterns of humans and its consequences on the environment, the economy and all other facets of civilization. This highly interdisciplinary nascent field, loosely termed “human mobility”, has seen contributions from geographers, social scientists, urban economists, public policy planners and most recently computer scientists and physicists. With collaborators in FIT, IFISC, Bristol, and CEA, we wrote a review on the exciting developments, published in Physics Reports.
