I do research in mathematics, especially number theory, but also in algebra and geometry.
I am a researcher in the CNRS, France, since Fall 1983, and professor in the Department of Mathematics at Texas A&M University, College Station, Texas, USA, since Fall 2002.
I have published two research books in my specialties!
My book on Geometry is entitled: Complex Ball Quotients and Line Arrangements in the Projective Plane; Click here for: Publisher's Webpage (Princeton Press) on my book.
My book on Number Theory is entitled: Periods and Special Functions in Transcendence; Click here for: Publisher's Webpage (World Scientific) on my book.
I invite you to read the resume of my career in mathematics!
