Feb. 11 is the United Nations’ International Day of Women and Girls in Science, which celebrates the achievements of women in STEM fields. This day is meaningful to our organization, which was founded by Dian Fossey, who pioneered groundbreaking research on the mountain gorillas in Rwanda. We work every day to continue Dian’s legacy, and are proud to be a place where women can pursue scientific careers, both in the field and behind the scenes, such as in our laboratories and classrooms.
Uncovering insights through lab analysis
Marie Rose Umuhoza (Rose) is a young Rwandan scientist who found her own unique role at the Fossey Fund after completing her bachelor’s degree in biotechnology. Rose works as lab coordinator at our Ellen DeGeneres Campus, where she spends much of her time processing gorilla fecal and urine samples, in what we affectionately call our “poop lab.”
Rose’s work is vital, as these biological samples we collect in the field give us insight into many aspects of the gorillas that we cannot see directly, including stress levels and even paternity.
To get an idea of the volume of this work, last year we reached a milestone of extracting hormones from an amazing 20,000 samples. “Processing over 20,000 samples is a huge achievement, and I’m incredibly proud to have played a role in this,” Rose said.
“It’s a testament to the hard work and dedication of the entire team, and it feels rewarding to know that our efforts contribute directly to a better understanding of the gorillas and how they’re impacted by their environment. It’s not just about the numbers; it’s about how those data can inform conservation strategies and help improve the lives of these magnificent animals.”

The importance of women in science
Rose feels especially connected to the International Day of Women and Girls in Science, as she is passionate about women pursuing scientific careers. Rose also provides training in lab techniques to up-and-coming scientists and students, helping to build local capacity for conservation research and promoting the growth of future conservationists.
“For me, this day is also a moment to reflect on my own journey and the incredible women who have inspired and supported me along the way. It also serves as an important reminder of how essential it is to encourage and empower more women and girls to pursue careers in science, technology and engineering, because science thrives on diverse perspectives.”

Rose wants to inspire any women or girls who have an interest in fields of STEM to pursue this path. “You absolutely belong in this field. Your ideas, perspectives and passions are incredibly valuable, and the world needs your unique contributions. Science is for everyone, and no dream or curiosity is too big to chase.”
