Contacting the Mathematics Department

Mathematics Department operations are being performed via a mix of principally in-person and some remote means.

The Math Department's main telephone lines, at (212) 650-5346 and 5347, are being answered Monday through Thursday by in office staff in the Marshak building, MR 529. Hours of operation for all days are from 9am - 5pm.

On Fridays, however, the staff sometimes operates remotely. As a result, calls to the department should then be directed to (347) 961-7667, which will generally be answered 9am-5pm.

Contacting Advisors and Program Administrators

For questions from students who are not mathematics majors or minors about mathematics courses, requirements, or concerning registration, please email the Math Dept at mathregistration@ccny.cuny.edu. If your question is about course registration, be sure to indicate your preferred sections for the course you are looking for, include your EMPLID and telephone number, and send mail from a CCNY email account making clear your major status and situation.

Undergraduate majors are advised by departmental faculty members, assigned for each student. See our Administrators page for information about whom to contact if you are Mathematics major or minor, or interested in becoming one.

The Administrators page lists administrators and advisors in the department together with some information about how to contact our administrators. This page can also be reached by clicking “Administation” on the menu at left.

Professor Feigon is the Graduate Chair of the Mathematics Master's program. It is best for questions about the graduate program to go to mathgradchair@ccny.cuny.edu.

Information about individual instructors is available on our People page.

New results on the dodecahedron

Picture of a dodecahedron with a closed straight-line path

Unlike the other platonic solids, the dodecahedron has a straight-line path (geodesic) from a vertex to itself. Actually, there are infinitely many, but in joint work of Prof. Hooper with Prof. Athreya (Univ. of Washington) and Prof. Aulicino (Brooklyn College), it was shown there are exactly 31 such paths up to certain “hidden symmetries.” The picture above shows one which can also be animated. This work was described recently in Quanta Magazine.
