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.

Zajj Daugherty's Advice for Applying to PhD Programs

Click here for some very comprehensive guidelines for continuing your education and really great advice for those interested in pursuing a PhD in mathematics.

Undergraduate Lecture Series:

The Math Department is organizing a student seminar designed to have faculty present accessible lectures to start conversations on advanced mathematics. These talks will be accessible to undergraduate students and cover a wide range of topics. For the Fall 2017 semester, we will meet in NAC 6/106 from 1:00PM-2:00PM on Thursdays. For more information, please check out the seminar website or join the Google group to be notified!

Tea Time:

Every Tuesday 1:00 PM The Math Club and [A.W.M.] meets in 6/270 for an afternoon tea to discuss the 'finer' things in life, and gripe about our classes.

Dr. Ethan Akin (CCNY), "Rock, Paper, Scissors, etc."

Dr. Ethan Akin (CCNY), "Rock, Paper, Scissors, etc." Professor Akin presents a group theoretic take on the traditional game of Rock, Paper, Scissors, and what happens when you extend the game to include even more objects. Fans of the TV show, The Big Bang Theory, will recognize the game's extension to 5 as "Rock-Paper-Scissors-Lizard-Spock." But what if you kept adding nerdy sci-fi references? How can you generalize a game to include n objects? Come find out!

Dr. Michael D. Grossberg (GSoE / Computer Science Department), CUNY Data Science Graduate Program
Michael Grossberg, one of the people heading CUNY's new Data Science program for Graduate Students, will be giving a talk to students interested in learning more about Data Science, opportunities in the field, and why you might be interested. This event is open to any interested students. Pizza will be served!


This prestigious national fellowship aims to encourage the most talented undergraduate students from groups traditionally underrepresented in graduate education—as well as others with a demonstrated commitment to eradicate racial disparities—to enter Ph.D. programs and pursue careers in research and college teaching. Benefits include:

-Academic guidance, faculty mentoring, and workshops that assist undergraduates to prepare successful applications to doctoral programs;

-Participation in an interdisciplinary peer group of outstanding students;

-$1,800 semester stipends for each of four semesters;

-$3,900 summer research stipends for two summers;

-Participation in an intensive 10-week academic summer program at the University of Chicago during the first summer of the fellowship;

-Monies for travel to attend academic conferences and to pursue research;

-GRE test preparation fees and doctoral application fees;

-$10,000 student loan repayment for graduates who pursue doctoral degrees;

-Continuing academic and financial support from the Andrew W. Mellon Foundation during doctoral studies and during years as a junior faculty member.

MMUF is available to students majoring in the humanities, areas studies, music theory, ethnomusicology, anthropology, sociology, political philosophy, ecology, mathematics physics, earth sciences, and computer science. Financial need is not a consideration.

For more information, contact members of the City College Fellowship Program Steering Committee: Susan Besse (History, Director), James Booth (EAS), Timothy Ellmore (Psychology), Isabel Estrada (Foreign Languages), Swapan Gayen (Physics), Norma Fuentes-Mayorga (Sociology and LALS), Andras Kisery (English), and Adrienne Petty (History)

The Program:

The program consists of three courses chosen from major areas in Algebra, Analysis, and Geometry respectively, specially designed and offered exclusively to MASS participants, and a weekly working seminar. Additional features include colloquium-type lectures by visiting mathematicians and mathematical projects involving research and creative use of computers.


Participants are selected from applicants who will be juniors or seniors in the following academic year (sophomores may be admitted in some cases). All participants are expected to have demonstrated a sustained interest in mathematics and a high level of mathematical ability and to have mastered basic techniques of mathematical proof. The expected background includes a full calculus sequence, basic linear algebra, a transition course with proofs (such as discrete mathematics) and advanced calculus or basic real analysis. The search for participants is nationwide. International applications are invited as well. Each participant is selected based on academic record, two recommendation letters from faculty, and an essay (international applicants should demonstrate their mastery of English).

Financial Arrangements:

Successful applicants currently enrolled in U.S. colleges and universities will be awarded the Penn State MASS Fellowship which reduces the tuition to the in-state level. Best efforts will be made not to increase their out of pocked expenses.
