I was born and grew up in France. I received an M.Sc. degree in mathematics from the Hebrew University in Jerusalem in 1975, a Diploma in engineering from the ENST in Paris in 1977, and a Ph.D. in applied mathematics from Brown in 1980. From 1980 to June 1991, I was a researcher with the French CNRS in Paris. I have been at Brown since 1991, as a visiting professor until 2000, and then as an associate professor of applied mathematics and neuroscience.
