Meet Cecilia Wangari: molecular diagnostics/environmental health

Snapshot of my continuing academic journey as a molecular diagnostics and environmental health professional. I am a PhD student passionate about developing molecular tools to improve health outcomes in vulnerable communities. My research focuses on detecting Schistosoma parasites in freshwater ecosystems using environmental DNA (eDNA) and Plasmodium in household trapped mosquitoes. These innovations aim to shift disease monitoring from a purely patient-centered approach to identifying where transmission occurs in the environment.

For diseases like schistosomiasis and malaria, screening people alone doesn’t tell us where they are contracting the diseases or where the risks lie. That’s why in our ATRAP (Action Towards Reducing Aquatic snail-borne Parasitic diseases) project , we focus on a transdisciplinary approach, understanding the interaction between the environment, people, and disease agents to contribute effectively to controlling or even eliminating vector-borne diseases.

My journey to this field has been both challenging and fulfilling. I have always wanted to contribute to improving community health. Initially, I hoped to study epidemiology but lacked the relevant experience. However, I didn’t give up. Instead, I pursued a Master’s in Sustainable Development at KU Leuven , supported by a VLIR-UOS scholarship. During my Master’s, I had the opportunity to work on female genital schistosomiasis in the Democratic Republic of Congo under the supervision of Dr. Tine Huyse. This experience was especially meaningful to me as a woman, addressing health challenges often neglected in women’s lives.

It hasn’t always been easy. In Africa, gender bias in science generally remains a significant barrier. When I first enrolled for an MSc program at Kenyatta University, I was the only woman in a class of five men. While I worked hard not to feel different, I wished there were other women with me. I’m glad this is changing, and I hope to inspire more women to pursue careers in science. Coming from a humble background, I know firsthand the power of perseverance and faith. I want to be a beacon of hope for young girls everywhere, showing them that their dreams are valid. Let no one stop you from achieving your goals. Dare to be different when needed, work smart, and trust in God to guide your path.

I feel incredibly blessed for the opportunities and recognition I’ve received. In 2021, I was honored with the MTAWA Outstanding Graduate Award. When I attended my first international conference, the European Multicolloquium of Parasitology (EMOP), I was humbled to receive three awards: Young Scientist Award, Audience Award and FAWPAR Award for the best oral presentation. It was an incredible and deeply affirming moment, reminding me that our work matters and makes a difference.

I am deeply grateful for the mentors and supporters who have been an integral part of my journey. I am especially blessed to have my husband and my mothers, who step into my motherhood role when I am unable to, and my family, whose unwavering belief in me fuels my determination. My son inspires me every day, his presence motivates me to work even harder, knowing that the example I set today shapes his future. Our work is not just about advancing science; it’s about creating tangible change in communities burdened by diseases like schistosomiasis and malaria. My story is a testament to the fact that with resilience, purpose, and a strong belief in yourself, anything is possible.

Meet Dr. Jacqueline N. Karithi, CEO, El-Koony Center, Kenya

J KariithiI am a Kenyan interdisciplinary environmental scientist who is passionate about tourism, conservation, and development issues. I gained interest in nature and the environment at a very young age, while traveling with family during the holidays. These moments sparked my interest to pursue a professional career in environmental science. By the end of my undergraduate studies, I developed a specific interest to explore the nexus of conservation and human impact and interventions.

A few years later, I completed my PhD in Environmental and Geographical Science from the University of Cape Town, South Africa, with a focus on Nature-based Tourism on the Mount Elgon ecosystem. At the start of my postdoctoral research at Princeton University, I focused on two specific areas: Reconciling livelihoods for community stakeholders in protected areas and Climate Resilient Agriculture as a biodiversity conservation mechanism for small-holder maize farmers in the Mount Elgon region. These research topics culminated in a detailed case study research analysis on various stakeholder groups in the Mount Elgon ecosystem in Kenya. This spurred my interest to focus my career on decision science having identified through my field experiences that applied science was essential to creating definitive change in all anthropogenic activities particularly in high biodiversity regions.

Thereafter, I began to develop the idea of establishing a landscape focused research center which was named, El-Koony Center, and launched in 2020. The El-Koony Center serves as a multi-purpose center, focusing on scientific research while providing professional and vocational training for community stakeholders in the Mount Elgon region.

I am a strong advocate for pursuing scientific research through an anthropocentric approach to create maximum impact on local communities. My work with El-Koony center has impacted the lives of the local population of the Mount Elgon region through various applied science projects that enhance livelihood opportunities for local communities such as the Climate Resilient Agriculture (CRA) project. This project has worked mainly with women farmers to recognize their input as the primary labor force in the region.

Additionally, I am currently working with female Masters and PhD students under my mentorship and thus connected with the MTAWA network to engage in their activities.  My dream for the center is to popularize decision science and make it the norm for those pursuing scientific careers to think about impact in a direct and meaningful way.

Meet Our Mentors: Dr. Mary A. Opiyo

Mary Opiyo
Dr. Mary A. Opiyo

Dr. Mary Opiyo is an Aquaculture Research Scientist at Kenya Marine and Fisheries Research Institute – Sagana Centre, Kenya.  Her every day work involves working in sustainable aquaculture projects dealing with broodstock development, seed production (Monosex tilapia and African Catfish), fish health management and fish nutrition.  She has 10 years of research experience, and project coordination in the freshwater aquaculture. She recently finalized her PhD in Fisheries Science from Kenyatta University and her thesis focused on the use of dietary probiotics in enhancing growth and immunity of Nile tilapia cultured in low input ponds. She came about this topic after several studies previously done indicated presence of pathogenic bacteria in low input ponds. Her PhD study gives solutions to production of safe and quality fish from low input ponds by smallholder farmers in rural areas because of high cost of feeds. Dr. Opiyo would like to encourage upcoming scientists/ PhD students, saying that with passion they can pursue their career/academic goal.  A PhD program requires a lot of time dedicated for research, which needs patience to get reliable results. Constant consultations with supervisors help a lot in project design and progression in data collection. Additionally, consultations with experts in the field help get ideas on carrying out laboratory work and data analysis leading to a smooth PhD journey.
