Conservation biology is the science of protecting Earth’s incredible biodiversity, from the tiniest insects to the largest mammals. At the Smithsonian’s National Zoo and Conservation Biology Institute (NZCBI), scientists are applying research and innovative tools to safeguard species across the globe.
Women have been at the forefront of this work for decades, shaping breakthroughs in research, fieldwork, and conservation strategies. Since 1972, they have played a vital role in advancing science and inspiring the next generation of conservationists.
Picture a Conservation Biologist brings these stories to life. Explore the videos below to meet the women driving discovery and innovation at NZCBI, and see how their curiosity, determination, and expertise help protect the world’s wildlife.

Meet Katherine Ralls — Conservation Biology Trailblazer
Ralls’ passion for mammals began in high school and — guided by a mentor — she pursued a groundbreaking career in science at a time when not everyone believed higher education was a worthwhile path for women. From studying zoo ungulates and California sea otters to advising on animal genetics and population health, she helped shape conservation biology as a formal field. In this video, hear her story, learn how she overcame challenges, and discover her advice for the next generation of scientists.
Meet the Panda Lady: Lisa Stevens
From starting as an animal keeper in 1978 to pioneering natural breeding for giant pandas and designing exhibits that showcase animal cognition, Lisa Stevens shaped the way we care for and study wildlife at the Smithsonian’s National Zoo. In this video, she shares her journey, the challenges she overcame as a Black woman in science, and the lessons she has for future conservationists — highlighting the power of curiosity, hands-on learning, and persistence.
Sally Bornbusch — Unlocking the World of Microbiomes
What if protecting animals starts with understanding the microscopic worlds inside them? From giant pandas to salamanders, Sally Bornbusch's research is helping scientists improve care, nutrition, and conservation strategies in entirely new ways. As part of a new generation of women advancing conservation biology, she also reflects on the mentors and experiences that shaped her path. In this video, discover how the cutting-edge science of the microbiome — and the people behind it — is transforming what we know about wildlife.
Melissa Songer — Mapping the Future of Conservation
As a leader in conservation science at NZCBI, Melissa Songer uses tools like GIS mapping and satellite tracking to understand how animals move through their environments—and how we can better protect them. From giant pandas to elephants and reintroduced species, her work connects science, technology, and communities to support wildlife around the world. In this video, she shares how conservation has evolved—and why speaking up and thinking boldly matters in science.
