# Mathematics at the 2007 National SACNAS Conference

| The 2007 National Conference of the Society for Advancement of Chicanos and Native Americans in Science (SACNAS) was held in Kansas City, MO, October 11-14. The conference theme, **"Stretching the Imagination to Support Leadership and Sustainability"** featured keynote speakers, sessions and symposia, awards, undergraduate poster presentations, graduate oral presentations, mentoring, and social events--and mathematics was again a significant component of the program. The American Mathematical Society (AMS) was among the conference session sponsors and was among the over 200 exhibitors--institutes, colleges, universities, associations, hospitals, government agencies--that provided information abouteducational programs and career opportunities in the sciences. Generoussupport from the National Security Agency (NSA) allowed many math students to attend the conference. |

| **2007 KEYNOTE ADDRESS SPEAKERS** **Richard A. Tapia** (Rice University) presented **Promoting Students' Appreciation for Math Through Applications to Very Cool Activities**. He is known for his research in computational and mathematical sciences and has received many awards and recognitions. His talk at this year's SACNAS conference connected mathematics to his hobby of drag-racing, and he shared the podium with two of his past students who had collaborated on a project to use math to determine the fairest way for drivers to be placed in lanes over several races. The Fall 2007 issue of *SACNAS News* (a pdf) features Tapia and other scientists in "Sustaining a Career in the Sciences," by Jenny Kurzweil. Richard Tapia received the AMS Award for Distinguished Public Service in 2004.

Her research focuses on equity in mathematics education; race, class and language issues in teaching and learning; effective teacher communities; and social justice. She has served as a member of the RAND National Mathematics Study Panel, and was recently a Fulbright Scholar researching collective teacher practices among secondary mathematics teachers in Zacatecas, Mexico. |

| The **UNDERGRADUATE AND GRADUATE STUDENT POSTER PRESENTATIONS IN MATHEMATICS** were a highlight of the conference. See the list of posters, presenters and photos. The poster award winner in Mathematics was **Brenda Jimenez-Gonzalez** from Instituto Tecnologico Autonomo de Mexico, for "The Cursed Duet: Dynamics of HIV/TB Co-Infection in South Africa." There were five **GRADUATE STUDENT ORAL RESEARCH PRESENTATIONS IN MATHEMATICS**. The graduate student Oral Presentation award winner was **Genevieve Toutain** from Arizona State University, for "A Mathematical Model of the *Drosophila *Heart." The other oral presentations in mathematics were: "Conduction Velocity and Interspike Interval in Models of Action Potentials in Myelinated Nerve Fibers," Eric Benavidez (University of Kansas, Lawrence); "Explicit Stochastic Models for the Population Dynamics of *Tribolium*," Alberto Izarraraz (California State University, Los Angeles, CA); "Visualizing Invariant Manifolds for the Planar Restricted Three Body Problem," Claudia Santiago (University of Chicago, Chicago, IL); and "Dynamics of a Gene Expression Model with Time Delay," Anael Verdugo (Cornell University, Ithaca, NY) Many of the mathematicians at the conference served as mentors and poster judges at the 2007 National SACNAS Conference, and several are part of the SACNAS Biography Project. |

The **AMS EXHIBIT** drew undergraduate and graduate students, mathematicians, and teachers. AMS Associate Executive Director **Jim Maxwell** and Public Awareness Officer **Annette Emerson** answered questions about the Society's programs and services, graduate school programs and careers in mathematics, and additional resources for students.

The AMS also provided visitors with materials including: "What Can I Do with a Math Degree?" poster in English and Spanish; **Mathematical Moments** in English and Spanish; information on **Headlines & Deadlines for Students**; brochures of resources for high school math students and teachers, for undergraduate math students, and for graduate students; and *Assistantships & Graduate Fellowships in the Mathematical Sciences*. Among the publications on display were *What's Happening in the Mathematical Science*s, by Dana Mackenzie and Barry Cipra, and *Change is Possible: Stories of Women and Minorities in Mathematics*, by Patricia Clark Kenschaft.
