Dan Guralnik received his Ph.D. from the Technion-IIT Mathematics department in 2005, specializing in Geometric Group Theory. After post-doctoral appointments at Vanderbilt University and University of Oklahoma, where he worked on asymptotic geometry and boundary dynamics of discrete groups, he moved in 2011 to a post-doctoral appointment at KodLab, the legged locomotion laboratory at the University of Pennsylvania, to start work on applications of topology and category theory to problems of knowledge representation in the context of navigation and control.…
