Ms Marylyn Gathiru

Marylyn Mugure Gathiru is an analytical chemist and researcher with a strong record of research, interdisciplinary collaboration, and science communication. She holds a Master of Science in Applied Analytical Chemistry and a Bachelor of Science in Industrial Chemistry with Management, with training that integrates laboratory-based analytical science, environmental assessment, and development-oriented research.

Her graduate research focused on the green synthesis and comparative analysis of biosynthesized and chemically synthesized Ag/TiO₂ nanocomposites, investigating the influence of reaction parameters and sustainability considerations. This work was conducted through collaborations involving academic and research institutions, including Kenyatta University and United States International University–Africa, and was supported by funding from the Environmental Protection Agency (EPA). The research contributed to peer-reviewed scientific publications.

In parallel, she has engaged in field-based environmental research, including Water, Sanitation and Hygiene (WASH) assessments and the evaluation of solar disinfection of drinking water (SODIS) under real-world conditions in informal settlements in Kenya. Marylyn has worked with and contributed to projects involving universities, research organizations, and development-focused institutions, applying analytical chemistry to environmental monitoring, water quality assessment, and public health–related challenges.

She has participated in and presented her research findings in academic and professional forums, including conferences and workshops associated with the Organization for Women in Science for the Developing World (OWSD). Beyond research, she has experience in scientific writing, data analysis, and stakeholder engagement, and is committed to translating scientific evidence into practical, context-sensitive solutions. Her professional interests lie at the intersection of analytical chemistry, water and environmental sustainability, and development, with a particular focus on strengthening the role of women scientists in addressing pressing challenges across Africa.
