About the QR Fellows

Quantitative Reasoning (QR) is the application of mathematical thought and knowledge to authentic, everyday issues; sometimes called quantitative literacy, QR is demonstrated by the inclination and ability to make reasoned decisions using fundamental mathematics. CUNY, as part its educational initiatives in the quantitative domain, has created a Quantitative Reasoning Fellowship. This QR Fellowship is awarded to a select group of doctoral candidates with strong quantitative expertise. The central responsibility of QR Fellows is to support efforts to strengthen mathematical and quantitative reasoning education at the colleges by developing resources and supporting faculty initiatives.  QR Fellows at SPS serve as tutors to help support students in courses with a quantitative component, like those involving math and statistics. 

QR Fellows are appointed on an annual basis and bring various skills to the SPS QR initiative. 

2017-18 QR Fellows

Ayse Sera Diebel,  is a Ph.D. candidate in Economics at CUNY Graduate Center. Prior to joining CUNY Graduate Center in 2013, she received her M.A. degree in Economics from Boston College, and B.A. degree in Economics from Bogazici University. Sera’s research interests lie at the intersection of empirical industrial organization and health economics. Her current research projects focus on the impact of payer-provider bargaining and consolidation on market structure and patient welfare.

Since 2014, Sera has been teaching both undergraduate- and graduate-level economics courses at several CUNY colleges as well as at Yeshiva University. Some of the courses she taught include Introduction to Econometrics, Introduction to Statistics, Methods in Mathematical Economics, and Microeconomic Theory. Sera is especially passionate about teaching quantitative subjects and believes that having a structured solution while simultaneously understanding the intuition behind each step is the key to not only grasping but fully understanding the material.

Ayse is available on email throughout the M-F week but has office hours at 119 W. 31st St. suite 406 on Mondays, 12:30-7 pm, and can be reached by phone on office days at 646-664-8643.                                             

QR Fellow Biwei Chen

Biwei Chen is a PhD candidate in Economics and Finance at CUNY Graduate Center. In his research, he applies advanced econometric and statistical tools to disentangle complex phenomena observed in financial markets and macroeconomy. He has taught major economics and finance courses at CUNY colleges, Yeshiva University and Columbia University. Throughout his teaching, quantitative reasoning methods play the pivotal role in enhancing students’ learning experience and computer skills. He has the ability to explain mathematics intuitively and graphically, helping students connect the dots and master the issues better. Biwei is available on email throughout the M-F week but has office hours at 119 W. 31st St. suite 406 on Wednesdays 12-7 pm. On in-office days, he can be reached by phone at 646-664-8633.
