CIS/GRASP Seminar: Jean Gallier, University of Pennsylvania, “Clustering of Unsigned and signed Graphs Using Normalized Cuts (Normalized Cuts 15+ years later)” Part 2

Jean Gallier is a Professor of Computer and Information Science at the University of Pennsylvania, with a secondary appointment in Mathematics. He obtained his Ph.D in Computer Science at UCLA in 1978. Gallier has done research in a number of areas of CS, including program correctness, incremental parsing and error recovery, logic programming, unification, term-rewriting and equational logic, polymorphic lambda calculi, and linear logic. For the past twenty two years, he has focused on geometric modeling, surfaces splines, surface reconstruction from meshes, and recently on optimization problems arising in computer vision, robotics, and machine learning. Generally, he is interested in applying geometric tools (in particular, differential geometry) to problems in computer science. He is the author of seven books, the next to the last one with Dianna Xu, “A Guide to the Classification theorem for compact surfaces,” and the last one, “Logic For Computer Science” (second edition).
