Christophe Golé was born in France and raised partly in northern Africa. He has held positions at the University of Minnesota, ETH (Zurich), the State University of New York at Stony Brook and University of California, Santa Cruz. He is currently the chair of the Department of Mathematics & Statistics at Smith.
Golé is the author of a book on dynamical systems, Symplectic Twist Maps, a survey of that subfield, in which he describes some strange objects that he baptized ghost tori—whose topology is an instance of the so-called Floer cohomology.
Golé's more recent research interest is in mathematical biology, and more specifically, plant pattern formation (phyllotaxis
