Uyen Pham spent part of her summer vacation in 2007 counting fruit fly eggs.

The high school senior participated in a research study at Vanderbilt University Medical Center to better understand the link between nutrition and fertility.

“I liked counting the eggs,” said Pham, who graduated in the spring of 2008 from Hillwood High School in Nashville. “It was very relaxing.”

Pham was a member of the inaugural class of seniors in the School for Science and Math at Vanderbilt, a research-centered learning experience offered to high school students in Metropolitan Nashville Public Schools by the Vanderbilt Center of Science Outreach (

During the school year, students receive college-level instruction and participate in research at Vanderbilt one day a week, while keeping up with their regular high school classes.

“One of the primary goals of this center is to connect university scientists and K-12 education,” explained center director Virginia Shepherd, Ph.D., professor of Pathology. “The school is a unique model of how that can be accomplished.”

Pham moved to the United States with her family from Vietnam six years ago. “Like all immigrants, we were looking for a better life,” she said. “My parents were hoping that my sister and I would receive better education ... and we did.”

When she was in ninth grade, a dedicated biology teacher, Cathy Morgan, inspired Pham with her hands-on approach to learning. Pham was fascinated with DNA extraction and other techniques, and was immediately interested when she came across the School for Science and Math while surfing the Internet for summer internship opportunities.

“I like the fact that science is always changing and growing,” commented Pham. “It’s intriguing and fun!”

Pham requested the field of developmental biology when she applied, and was pleased to be placed in the lab of Daniela Drummond-Barbosa, Ph.D., assistant professor of Cell and Developmental Biology.

It is well known that poor diet negatively affects fertility. In the fruit fly, Drosophila, a protein-poor diet causes egg production to drop. The Drummond-Barbosa laboratory has shown that this ovarian response to diet involves the insulin signaling pathway.
