Summer Undergraduate Research Experience
Since the spring 2000 semester the Mathematics Department has sponsored a number of summer research experiences (SURE) for a selected number of undergraduates math majors. The Summer Undergraduate Research Experience is aimed at current undergraduate math students in their junior year or advanced sophomores. The project ends with an oral presentation in the beginning of the fall semester.
Funds to support this activity are limited and student participants are chosen by a faculty committee based on grades, coursework, and fit between their research interests and those of the supervising faculty. Applications are considered more highly if students have found a faculty mentor and research topic. To apply for this program please use the application below:

Alex Ancheta (VIGREsupported) was a student in the new course, Mathematical Neuroscience, which Professors David McLaughlin and Michael Shelley offered in Spring 2001  a course designed to introduce undergraduate and graduate students to research topics in mathematical neuroscience. Dr. Louis Tao (a postdoc at the Courant Institute and the Center for Neural Science) assisted in the development and presentation of the course. The students also joined the visual neuroscience working group, attending the working seminar "Neural Tuesday." Alex began an undergraduate research project in summer 2001, which continued during the academic year and will continue into summer 2002. During the academic year, his research work will be applied toward an undergraduate honors thesis. The research project studies coarsegrained mean field approaches to global modeling of the primary visual cortex. The work began with a literature search to unveil coupling architectures between the cortical layers of V1, from anatomical laboratory observations. Alex then constructed the architecture of an idealized network and began the construction of a numerical model under the largescale scientific computational guidance of Professor David Cai.
Rachel Blumberg studied mathematical modeling of epidemics and the evolution of gene frequencies under the pressure of natural selection with Professor Daniel Tranchina. Rachel studied both discretetime and continuous time models with an emphasis on the formulation of equations and on their numerical solution. Rachel learned about firstorder and secondorder accurate methods for solving systems coupled nonlinear differential equations and how to implement these methods in Matlab. Other topics touched on include phase plane analysis, analytic solution of trajectories, and Monte Carlo simulations for small population sizes.
Darin Comeau (VIGREsupported) worked with Professor LaiSang Young and William Cowieson (VIGRE Postdoc) in the summer of 2001. As a preparation he read Devaney's book "An Introduction to Chaotic Dynamical Systems" and successfully completed two projects. In the first, he worked out by himself, following hints from a book, a proof of Sarkovskii's Theorem. (Sarkovskii's Theorem is a well known theorem  with an elementary proof  concerning periodic behavior for onedimensional maps.) The proof was written up formally in a report. Comeau's second project was to carry out a numerical study of the H\'enon maps. Using Matlab, he discovered a number of properties of chaotic attractors. Comeau is currently (Spring 2002) enrolled in an Independent Study course with Young and Cowieson. The topic for this course is the mathematical theory of fractals.
David Lorentz (VIGREsupported) was another student in the Mathematical Neuroscience course offered by Professors McLaughlin and Shelley in spring 2001. David then began an undergraduate research project in summer 2001, which continued during the academic year and will continue into summer 2002. The research project involved a study in cortical visual processing of the effects of a slow receptor (NMDA) and its comparison to the much faster AMPA receptor. First, models of the nonlinearity of the NMDA receptor were studied and developed  comparing the accuracy and efficiency of different representations for use in largescale neuronal network models. The work involved literature searches, computational modeling, and postprocessing. David is currently developing an idealized network of simple and complex cells  comparing the relative effects of AMPA and NMDA receptors on the neurons' performance characteristics.
Tim Novikoff (VIGREsupported) was a third student in the Mathematical Neuroscience course offered by Professors McLaughlin and Shelley in spring 2001. Tim also began his undergraduate research project in summer 2001, which continued during the spring semester 2002 into summer 2002. His research project began with a study of the theoretical mechanisms behind the nonlinearity of the NMDA receptor. It then turned to the construction of very idealized models of neuronal networks with both simple and complex cells present, in which the performance of phased averaged networks were compared with that of networks with selective coupling mechanisms which produce inhibition in "pushpull" antagonism to excitation.
Patricia Tong (VIGREsupported) worked with Professor Robert Kohn and two graduate students, Oana Fainarea and Pedro Judice, on a problem of optimal investment strategies using options. Her project addressed the following question: consider an investor who wishes to speculate on a stock by buying call options rather than the stock itself. How should this investor decide which calls  i.e. which strike prices  to buy? In giving this problem a mathematical formulation, Tong was led to read about the BlackScholes theory of option pricing and the Capital Asset Pricing Model of portfolio optimization. But she also learned that the answer did not lie in these standard tools alone. With further modeling, she did find a suitable answer, which she is now writing up (with Kohn's guidance) in a form suitable for publication. Patricia participated in an REU at Worcester Polytechnic Institute during Summer 2002.
Brad Weir worked with Professor Richard Pollack on "Algorithms in real Algebraic Geometry." In fall 2001, Brad worked through the first chapter of the book of the same title. He has digested the Lefschetz principle (quantifier elimination over algebraically closed fields and the associated transfer principle. This spring he will start thinking about problems related to the TarskiSeidenberg principle (quantifier elimination over real closed fields) and the basic topology of semialgebraic sets.
Elizabeth Zollinger (VIGREsupported) worked with Professors Charles Newman of the Courant Institute and C. D. Howard of Baruch College on simulations of certain dependent percolation models arising from interacting particle systems and cellular automata. After a preparatory period in spring 2001, in which Elizabeth learned about percolation and interacting particle systems, the project itself began in summer 2001 and continued in fall 2001 and spring 2002. (Elizabeth received VIGRE support during all these periods.)
