Contacting the Mathematics Department

Mathematics Department operations and instruction are mostly being performed in-person, but due to the ongoing public health risks there are still some remote components.

The Math Department's main telephone lines, at (212) 650-5346 and 5347, are being answered Monday through Thursday by in office staff in NAC 8/133. Hours of operation for all days are from 9am - 5pm.

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

Preferably, email your concerns and questions to math@ccny.cuny.edu, which is being monitored regularly.

Contacting Advisors and Program Administrators

During January, advising will be handled online.

For questions concerning registration, e.g. possible overtallies, please email the Math Dept at math@ccny.cuny.edu. In addition to indicating your preferred sections(s) for the course you are looking for, please be sure to include your Empl ID and telephone number (for a quicker back and forth about available sections). Your email will be forwarded to an advisor.

For questions about changing a Major or Minor, you should get a response from the Assistant Chair, Prof. Joseph Bak, who advises undergraduate Mathematics majors. Prof Bak usually responds in a day or so.

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.

Professors Jorgenson and Chinta are co-Chairs of the Mathematics Master's program. It is best to contact them by writing to mathgradchair@ccny.cuny.edu.

Contacting instructors

Information about individual instructors is available on our People page.

Meet new mathematics faculty: Prof. Weilin Li

The math department is pleased to welcome Prof. Weilin Li to the department beginning Fall 2022.

Prof. Li comes to CCNY as an assistant professor starting Fall 2022. His research lies in computational harmonic analysis and includes applications to signal processing, machine learning, and data analysis.
