My name is Ahmad, and I am currently a postdoc in the department of mathematics at KTH working with Maurice Duits. Before that I was a postdoc at University of Michigan working with Peter Miller. I completed my PhD at IUPUI under the supervision of Maxim Yattselev.
I am a co-organizer of the Random Matrices, Stochastic Models, and Analysis seminar. During Fall '24, I am organizing the postdoc scientific activities in the Random Matrices and Scaling Limits program at the Mittag-Leffler Institute.
