Women of Brookhaven Lab

At Brookhaven Lab, we understand that innovation is not possible without a diversity of thought and perspective, so we promote equal opportunity and advancement of women in support of world-class science. We also encourage young women towards careers in science, technology, engineering, and mathematics (STEM) to seed the next generation of discovery.

Meet some of our Lab’s inspiring women who are a driving force for many of our scientific breakthroughs.
