A City College graduate, and later Mathematics Professor, Jesse Douglas, was a recipient of the first Fields Medal in Mathematics -- regarded by the profession as the equivalent of the Nobel prize. Nobel laureates Herbert Hauptman in chemistry, Kenneth Arrow and most recently Robert Aumann (2005) in economics, were former City College math majors who received their Nobel prizes for highly mathematical work.

Indeed, dozens of our graduates, having received a rigorous and inspiring education from the College, have achieved recognition as world leaders in all fields touched by mathematics. Hundreds of others have become mathematics educators, business executives, and respected faculty in colleges and universities throughout the country.

We invite you to share in this magnificent tradition. Whether you are just beginning college-level mathematics, or are interested in graduate study, or are somewhere in between, you will find in our Department the instruction you need. We offer a wide selection of introductory and advanced courses, taught by an outstanding group of dedicated faculty, many of whom are internationally renowned mathematicians. Browse through our site to learn what we have to offer and how we can use our talents to help you develop yours.

Meet new mathematics faculty: Cheikhna Mahawa Diagana

Our newest full-time faculty member in the mathematics department, Cheikhna Mahawa Diagana, is not new to City College. Cheikhna has been teaching math courses here for the past nine years. During that time Cheikhna has studied math and worked as an Adjunct Lecturer in undergraduate calculus courses at NYU. He also served as a TA in graduate courses such as Complex Analysis and Real Analysis at NYU.

At City College Cheikhna has been one of our most enthusiastic math teachers. If you have taken a class with Cheikhna, you know that he loves talking about math and working through math problems with City College students. This is not surprising. Cheikhna was once a City College math student himself. He received a BA in pure mathematics from CCNY in 2008 and a MS in mathematics from NYU in 2012.
