Summer 2020. The mentors this year are Matthew Junge, Guy Moshkovitz, Adam Sheffer, and Pablo Soberon. The participants (in alphabetical order):

  • Riti Bahl

  • Luis Benitez Norat

  • Travis Dillon

  • Clare Hamblen

  • Anqi Li

  • Jack Messina

  • Hanna Mularczyk

  • Kukai Nakahata

The program is partially funded by NSF awards DMS-1802059, DMS-1851420, DMS-1855516, and DMS-2028892.        

The CUNY Combinatorics REU is a program for undergraduates, focused on doing combinatorial research with the goal of publishing a research paper. The program runs for 7-8 weeks during the summer in New York City. During this period each participant is closely mentored by the organizers. We are based in the math department of CUNY's Baruch College, located at the heart of Manhattan.

The program is currently organized by Adam Sheffer and Pablo Soberón. In addition to intensive research work, the program includes many events: meetings with senior mathematicians, meetings with other REU programs, social events, mathematical talks, and more.

Topics. The research projects are in discrete geometry, additive combinatorics, topological combinatorics, and related topics. No previous familiarity with these topics is required. For some basic introduction to these topics:

  • For a glance at Discrete Geometry, see Chapter 1 of this book (it may be helpful to first skim the introduction).

  • For a glance at Additive Combinatorics, see this chapter.

Additional details. For the summer of 2020, the number of participants will only be set around January/February. Each participant is expected to be in NYC for 7-8 weeks during the summer. The default dates are June 15th - Aug 7th, but participants can ask for small changes. Each participant will be provided with a stipend of $6,000 for accommodation, food, and other expenses. We will also provide access to reasonably priced dorms. (Depending on potential NSF funding, this may change to a $4,500 stipend + free housing).

Participants can work on their own individual project or may choose to work in groups. Each participant receives a fully equipped cubicle in the math department, close to the offices of the mentors.


Beyond doing research work, the participants will get trained in giving math talks, writing rigorous proofs, and other related topics. After the program ends, we keep supporting the participants as they continue in their mathematical pursuits. 

Applying to the REU. We are looking for undergraduates who are strongly motivated to produce a research paper, are hardworking, and can work independently between meetings with the mentors. Please apply only if you think that you will be able to get yourself to spend long periods of time working hard on mathematical research. 

Since the stipends are funded by NSF, only US citizens or permanent residents can apply. If you are a senior, your graduation date must be after the period of the REU. If you do not satisfy these requirements but may have an alternative official source of funding, you are welcome to contact us to discuss this. Funding your stay with your own money is not permitted. 

Applications are submitted through An application includes at least one reference letter, a CV (or resume), a transcript, and any additional information you wish to add. You may submit more than one reference letter. If you participated in a previous research project, a letter from your mentor in that program would be appreciated. The transcript does not need to be an official document. Under additional information you can add past research projects, a personal statement, and/or any other relevant information. Please make sure to indicate that you are a US citizen or a permanent resident.

The applications deadline is Feb 19, 2020. We expect to make the first offers 7-10 days later. (There are usually several rounds of offers, so not getting an offer after two weeks (or even four) does not mean anything.)

You are very welcome to contact us at for any questions, clarifications, or issues.
