Ruth Wambua’s Research
Ruth Wambua’s doctoral research at United States International University–Africa (USIU-Africa) centers on digital transformation, with a strong focus on digital health systems and equitable access to services.
Her work is built on the understanding that while technology has the potential to revolutionize healthcare and education, it often leaves behind communities with limited access to infrastructure, skills, or financial resources.
Focus on Digital Health and Equity
Wambua’s most recent studies examine how digital health tools, such as telemedicine platforms, mobile health applications, and online health records, can be implemented to support universal health coverage (UHC).

She identifies the barriers that hinder effective adoption, including:
- Digital literacy gaps among healthcare workers and patients.
- Infrastructure challenges, such as poor connectivity and unreliable electricity.
- Affordability issues prevent vulnerable populations from accessing necessary devices or services.
- Policy misalignments between government strategies and implementation on the ground.
Her 2025 paper, “Moderating Effect of Demographic Factors on the Relationship Between Digital Health and Universal Health Coverage Equity in Kenya,” explores how age, gender, income, and location influence the success of digital health initiatives.
Digital Innovation in Higher Education
Beyond healthcare, Wambua has also contributed to research on digital innovation in higher education institutions.
In her 2022 paper, “A Systematic Review of Digital Innovation in Higher Education Institutions in Developing Countries,” she reviewed strategies used by universities to integrate technology into teaching, administration, and research.
