We are pleased to welcome a new Advanced Fellow soon

Peter Koymans received his PhD in mathematics from Leiden University under supervision of Jan-Hendrik Evertse and Peter Stevenhagen, and later held postdoctoral positions at the Max Planck Institute for Mathematics and the University of Michigan. His research is in various areas of number theory with his main field being arithmetic statistics. He has worked on Diophantine equations, unit equations, the circle method, the distribution of class groups and the negative Pell equation. His work on the negative Pell equation was covered by Quanta Magazine. He is currently working on Chowla's non-vanishing conjecture, Malle's conjecture and Greenberg's conjecture.
