The conference "Classical and quantum hyperbolic geometry and topology," co-funded by the Office for Science and Technology of the Embassy of France in the US, took place the week of July 6-10, 2015 in Orsay, south of Paris. It was an opportunity to celebrate the contributions of Professor Francis Bonahon, a personification of the deep connections between the US and French mathematics communities, two of the most brilliant in the world.

Francis Bonahon was born in 1955 in Tarbes, southern France. He studied mathematics at Ecole normale supérieure (Paris) and later at Orsay university, where he defended his PhD thesis in 1979 under the supervision of Laurent Siebenmann. After a few years at CNRS, he emigrated to Los Angeles where most of his career took place at the University of Southern California (USC). He has received numerous scientific awards. His research focuses on non-Euclidean geometries and, more recently, on questions with strong geometric content emanating from quantum physics. An author of many elegant and deep results, he is also an accomplished popularizer of science: see for instance this video
