Amadou Bah

I am a Ritt assistant professor in the mathematics department of Columbia University since September 2021, working in Arithmetic Algebraic geometry.

Before that, I was PhD student at Université Paris-Saclay. I was based at the Institut des Hautes Études Scientifiques, where my advisor was Ahmed Abbes.
