What excites you about science?
The ability to apply science to our daily lives in managing the world around us is clear evidence that we cannot live without science. Science has led to innovations in food systems, healthcare, and technological advancements, making life easier for humans in many aspects and promoting their health and well-being. These advancements have sparked a deeper passion in me for research, as well as a strong desire to acquire novel knowledge and skills for improving food and nutrition security; women and children’s health.
When did you realize science was for you?
As a young girl in high school, I was inspired by female teachers who taught science-related subjects, especially during a time when science was often seen as a field meant for boys. Attending science and biology classes allowed me to see how science is applied in the real world to improve health, enhance food productivity, and solve significant issues. Learning about how early scientists conducted experiments to address real-life problems, such as the discoveries of scurvy and kwashiorkor, sparked my curiosity and deepened my desire to study science.
Moreover, as an undergraduate student, field attachments further enhanced my understanding of how science can improve household food security and the health of women and children. This experience further strengthened my desire to pursue a career in a science-related field.
Who is your role model?
Well, I have two role models; my uncle Mr. Sam Thunde and my mentor Dr. Magaret Kubwalo-Chaika. My uncle was among the first university graduate in our family who inspired me to work hard, be selfless, set goals in life, strive to achieve the goals and give back to the community or always practice generosity.
On the other hand, Dr. Margaret further inspired me to be unapologetic when it comes to exploring life’s opportunities and aligning my goals, career with hobbies and being a prayerful woman. Through their mentorship, I have been challenged to become a goal getter and integrate my career with entrepreneurship and social life.
What is the greatest challenge I have had to tackle?
Managing the loss of my husband in 2021 as a young woman was quite challenging for me. Going through loss at the same time striving to maintain my career, mental health and family was daunting. The transitions that I have gone through over time have motivated me to advance my career, acquire a new set of skills in project management, engage in new hobbies, including modern farming, and inspiring young girls to consider venturing into science career paths through group motivational career talk.
Where do I see yourself in 10 years?
My long-term goal is to become an international researcher specialized in global health, with a focus on maternal and child nutrition. I aim to build research skills and capacity, particularly for emerging researchers, especially young women in developing countries, through training and mentorship. I also plan to lead the implementation of global health, nutrition, and food systems programs across Africa and beyond. Additionally, I aspire to drive evidence-based programming in maternal and child health by integrating research into policy and strategies. To achieve this, I will collaborate with global research institutions, governments, and development partners, ultimately working to improve health and nutrition outcomes of women and children.
