Ph.D. in Mathematical Sciences

66-credit doctorate (36 credits above master’s)  I  On-Campus in New York City  I  Full-Time or Part-Time

The Ph.D. in Mathematical Sciences at offers training and research opportunities in traditional areas of mathematics as well as in interdisciplinary applications of mathematics. Students in the program can specialize in (i) pure and applied mathematics, or (ii) computational science. Faculty research include areas such as dynamical systems, celestial mechanics, dynamical astronomy and astrophysics, partial differential equations, geometric analysis, algebra, combinatorics, mathematical physics, network science, operator theory, spectral analysis, quantum field theory, mathematics of finance, computational topology, biostatistics, machine learning, computer vision, manifold learning.  Students graduating from our Ph.D. program are prepared to pursue mathematics at the highest levels, in colleges and universities, government, healthcare, research and development. 

The Ph.D. program offers three tracks: 

  • Track I: Three years of study for students who enter with 60 credits of graduate coursework  
  • Track II: Four years of study for students who enter with 30 credits of graduate coursework 
  • Track III: Five years of study for students who enter with no previous graduate coursework  

Besides coursework, students are required to pass a qualifying exam and to complete a doctoral thesis on original research.

has an exceptional tradition and legacy in mathematical physics and an impressive track record of training research mathematicians. Famous alumni include Hillel Furstenberg (Abel Prize in Mathematics 2020), Benjamin Weiss, Michael Aizenman and Charles Peskin. We also leverage our excellent locations in midtown and uptown Manhattan to provide our students access to many seminars and conferences in the New York metropolitan area, to facilitate internships with major companies, and to develop connections and land in competitive jobs within or outside of academia.

According to the U.S. Bureau of Labor Statistics, the annual wage as of 2022 for jobs in mathematics: actuary ($113,990); postsecondary education administrator ($99,940); mathematician and statistician ($99.960); operations research analyst ($85,720); and postsecondary mathematics and science teacher ($80,840).

Various scholarships and financial aid are available. A limited number of teaching and research assistantships, which include a tuition waiver and a stipend, are available on a competitive basis.

Program Highlights

Exciting research projects such as on the fractional Laplacian, chaos theory, energy harvesting, solar system and galactic dynamics, black holes, big-bang singularity, financial bubbles, topological insulators.

Engagement in research leading to publications in peer-review journals and participation in national and international conferences.

Building a robust theoretical foundation, proficiency in applying mathematics to real-world problems, and mastery of computational abilities.

Opportunities to develop pedagogical skills through teaching courses, recitations, and computer labs.

External funding opportunities through the NSF, NIH, NASA, Simons Foundation, Sloan Foundation, Keck Foundation, and other funding agencies.

Students can take graduate courses at the CUNY-Graduate Center through a cooperation agreement.

Knowledge Requirements

Successful incoming students to the Ph.D. program have mathematical skills, which is often demonstrated by a master's degree and a strong master's thesis. Exceptional students may be admitted to the program without a master's degree and can earn an M.A. degree in mathematics while pursuing their Ph.D. studies. Those applicants must meet admissions requirements for both the M.A. and Ph.D. programs.

Most of our students have an undergraduate degree or other experience in economics, mathematics, computer science, physics, chemistry, engineering and similar quantitative majors. Some students also come from finance and behavioral sciences so long as they’ve taken several mathematics courses. The faculty believe it's academically important to include students from a variety of different backgrounds and with a diverse set of experiences. 

Prerequisites include one course in multivariate calculus (Calculus 3), one course in linear algebra and one course in statistics/probability with a grade of B or better.
