Mathematics at the 2005 SACNAS National Conference

The Colorado Convention Center

The 2005 conference of the Society for Advancement of Chicanos and Native Americans in Science (SACNAS), was held in Denver, Colorado, September 29-October 1.

What's going on inside the Convention Center at the SACNAS conference? The conference theme, "Science for America's Future" featured keynote and conference speakers, awards, undergraduate poster presentations, graduate oral presentations, and social events--and mathematics was a significant part of the program. The American Mathematical Society (AMS) was among the conference session sponsors and was among the 257 exhibitors--institutes, colleges, universities, associations, hospitals, government agencies--that provided information about educational programs and career opportunities in the sciences. Generous support from the National Security Agency (NSA) allowed many math students to attend the SACNAS Conference.

The prizewinning poster in mathematics was Modeling Interaction of Predator and Prey Populations on Dynamic Habitats, presented by Julijana Gjorgjieva.


Ellen Maycock and Mike Breen in the AMS booth Mathematicians Ellen Maycock (Director, AMS Meetings & Professional Services) and Mike Breen (AMS Public Awareness Officer) were in the AMS booth to talk to students about graduate school and career options.
The AMS exhibit drew K-12 science teachers, undergraduate and graduate students, Research Experiences for Undergraduates leaders and faculty. The AMS handed out Interest Data Collection Forms for the Joint AMS/MAA/MSRI/NAM/NCTM project to maintain a record of the professional interests of mathematicians and mathematics educators from underrepresented minority groups.

Change is Possible, The exhibit included books, "What can I do with a math degree?" poster, brochures of resources for high school math students and teachers, for undergraduate math students, and for graduate students. Copies of Assistantships & Graduate Fellowships in the Mathematical Sciences were available for undergraduates considering graduate school in mathematics. The AMS held a raffle to give away a copy of the new AMS publication, Change is Possible: Stories of Women and Minorities in Mathematics, by Patricia Clark Kenschaft. The book includes life stories of SACNAS members Cleopatria Martinez, William Vélez, Richard Tapia, and Manuel Berriozábal.


Karl, Matt, Julijana, Mike, Jason, Jing, and Clara The AMS presented Who Wants to Be a Mathematician during during the breakfast on Friday, September 30. AMS Public Awareness Officer Mike Breen emceed the well-attended event, and game co-creator Bill Butterworth (DePaul University) ran the presentation and served as judge. The evening before the game nearly 40 undergraduate students took the qualifying test to participate.

Co-chairs: Ivelisse Rubio (University of Puerto Rico in Humacao) and Stephen Wirkus (California State Polytechnic University)

BIOASTATISTICS AND EPIDEMIOLOGY: THE INTERSECTION OF MATH, SCIENCE AND PUBLIC HEALTH Professional Devlopment Session. In-kind support provided by the Department of Biostatistics and the Department of Epidemiology, Harvard School of Public Health.
Presenters in the fields of statistics and biostatistics included Scarlett Bellamy (University of Pennsylvania)) and Javier Rojo (Rice University) and Louise Ryan (Harvard School of Public Health and the Dana-Farber Cancer Institute)

Thanks to the mathematicians who organized sessions, judged the math posters, mentored students, encouraged particiaption in the Who Wants to Be a Mathematician game, and visited the AMS booth. Many of them are part of the SACNAS Biography Project.
