In this week's installment of our "Micro Management Stories" video series, we're featuring Lynne Meryl Mofenson—chief of the pediatric, adolescent and maternal AIDS branch of the National Institutes of Health.

Mofenson received a 2012 Service to America medal, as federal employee of the year, for her work domestically and internationally in service of AIDS research. Since arriving at the NIH in 1989, she has led many of the organization's most prominent efforts around AIDS, particularly its advances in reducing the transmission of the disease between mother and child.

In this video, the pioneering physician talks about how she was decidedly uninterested in becoming a doctor when younger—and how a change of perspective changed the course of her life's work.

Watch her video above.
