This year’s contestants were Tushar Chawla’16, Weissman Mathematics; Bell Chen’17, Weissman Mathematics; Jonathan Romero’17, Zicklin Accounting; and, Gehua Zhang’17, Zicklin Mathematics. The team was prepared by Professor Jarrod Pickens, who also coached Baruch’s winning Rotman International Trading Competition in February, and by Baruch MFE student Anik Roy.

“Participating in this competition was a tremendous learning experience for our students,” said Dan Stefanica, co-director of the Master’s in Financial Engineering (MFE) program. “Preparing for the competition taught them about the algorithmic nature of the work, and being there, and winning the options market making case in competition with future traders from top schools around the country built confidence for their soon to be launched careers.”

Baruch’s team won the Options Market Making category, placed third in Cross-listed Shares Trading, and 10th in Algorithmic Sales & Trading. “Most importantly, our trading strategies had moderately high expected returns, but very low risk – we were in top eight in 8 out of 9 trading rounds in the competition,” says Stefanica.

The nation’s primary algorithmic trading competition, the UChicago Midwest Trading Competition serves as an opportunity for quantitatively driven students interested in financial markets to connect with premier financial services firms in the Chicago area.

Students who need to take these courses receive a letter in June inviting them to register. It is strongly recommended that invited students participate in this tuition **free** program, it is required for SEEK and Prelude students.

The program begins after the July 4th break, and is offered in both the day and evening. The day program includes regular classroom instruction, tutoring and computer assisted instruction. The evening component has longer classroom instruction as it does contain tutoring or computer assisted instruction. The program runs six weeks, ending in mid August.

The courses offered in the Program are:

FSPM 0121: This course is identical in content to CSTM 0120 and covers topics in intermediate algebra. Students placed into this course have demonstrated a knowledge of elementary algebra. Students completing this course may register for MTH 1030 – College Algebra, in the fall.

FSPM 1031: This is a college algebra course, identical in content with MTH 1030. Students completing this course may register for MTH 2003 – Precalculus with Elements of Calculus, in the fall.

]]>Anita Mayo received a BA from Barnard College and a Ph.D. in mathematics from the Courant Institute, NYU. Her areas of specialization are numerical analysis, applied mathematics and, more recently, computational finance. In her work she has developed rapid and highly accurate methods for solving a variety of differential equations on general regions. She has applied these techniques to solving problems in elasticity, electrodynamics and fluid mechanics, including ones directly arising in the manufacture of IBM chips and recording devices. In particular she has helped engineers develop programs used for modeling deposition in CMOS manufacture and programs that were widely used for modeling thin film recording heads. She has also developed rapid methods for pricing certain financial options.

**Research Interests **

My current research falls into two broad areas of application of probability theory: spatially disordered systems, and computational finance.

Spatially disordered systems is a class of probabilistic models generally motivated by physical problems arising in condensed matter physics and materials science. Two types of systems that I study are called first-passage percolation (FPP) and stochastic Ising dynamics. FPP has applications in areas as seemingly diverse as properties of porous media (aquifers, membranes, etc.), the growth of cancerous tumors, the propagation of cracks through concrete, and the flow of electricity through networks. Ising models capture some of the fundamental features of magnetized materials.

My work in computational finance generally focuses on the application of probabilistic methods and arbitrage-free pricing theory in valuing financial instruments and quantifying risk. It is practical in nature, much of it motivated directly by industry applications.
