International Day of Women and Girls in Science is a time to celebrate the contributions of women to scientific discovery and to recognise the journeys that shape their work. 

Today, we highlight Haddijatou Mbye and Thorey K. Jonsdottir, two scientists whose paths into research reflect curiosity, resilience, and a shared commitment to improving global health. Their stories show the importance of representation, mentorship, and community in creating a more inclusive future for women and girls in science.

Haddijatou’s path into science began with a deep curiosity about health and disease, shaped by seeing how limited access to quality healthcare affects families in her community. An early experience working in clinical laboratories transformed that curiosity into conviction, revealing how scientific work contributes directly to diagnosis, patient care, and improved lives. For her, science has never been only about building a career. It is about making a difference and inspiring young girls who may not yet see themselves represented in scientific spaces.

Her journey has also required quiet strength. Managing an anxiety disorder while navigating demanding academic and professional environments has brought moments of self-doubt and exhaustion. Yet with mentorship, support, and a commitment to her well-being, she has continued to move forward. Her experience has reinforced her belief that success in science does not require perfection, only persistence and care for oneself and others.

“My journey in science is driven by curiosity and purpose, and even with anxiety, I continue to move forward. I have learned that with determination and support, it is possible to grow, succeed, and find your place in science.”

Thorey’s story began with an early love of chemistry and biology, nurtured by inspiring teachers. What once seemed destined to be a career in medicine gradually evolved into a passion for biomedical research, leading her to study malaria parasites on the other side of the world and pursue doctoral research to understand how these tiny organisms survive within red blood cells. Mentors, colleagues, and the excitement of discovery have continued to shape her scientific journey.

Her path has also included challenges. For example, moving overseas for her studies brought stress (visa, money, language, distance from home), uncertainty, and a big step outside her comfort zone. She has also experienced waves of imposter syndrome during her career. She has navigated these difficulties through supportive networks, mentorship, and conversations with colleagues and friends. Beyond her research, Thorey contributes significantly to Women in Malaria, an initiative that strengthens representation, visibility, and leadership opportunities for women in malaria research. Thorey also volunteers for Global Parasitologist Coalition, where she sketches parasite comics to help promote the world of parasites to a broader audience and inspire the next generation of scientists. “Never be afraid to fail, always stay curious and keep pushing forward. Women helped shape the history of science and will continue to do so, but this time let’s be fair and acknowledge them from the start.”

Together, Haddijatou and Thorey’s journeys show that science is not only about discovery but also about building communities, overcoming challenges, and creating opportunities for the next generation. This International Day of Women and Girls in Science celebrates their courage, resilience, and the example they set for young girls everywhere, proving that curiosity, determination, and support can transform both lives and science itself.
