How Dr. Osadolor Ebhuoma is Redefining Disease Surveillance in Africa

By Tosin Clegg

As Sub-Saharan Africa grapples with the persistent burden of vector-borne diseases, a quiet revolution is unfolding in how scientists predict and respond to outbreaks.

Malaria remains the region’s most dominant public health threat, but rising incidences of dengue fever, yellow fever, and schistosomiasis are further stretching already limited health infrastructure.

In this era of increased climate variability and rapid urbanization, traditional methods of disease surveillance are proving insufficient. What is emerging in their place is a powerful convergence of disciplines such as geospatial intelligence, environmental science, public health, and data analytics led by experts like Dr. Osadolor O. Ebhuoma.

Dr. Ebhuoma is one of the leading voices in applying spatial data science to combat public health crises in Africa. With a doctorate in Environmental Science from the University of KwaZulu-Natal, a Master’s in Safety, Health, and Environment from the University of Salford in the UK, and a Diploma in Computer Programming from Sheridan College in Canada, he embodies a rare blend of scientific, technical, and policy-oriented expertise. His academic and professional journey has prepared him uniquely to approach health challenges with tools from multiple disciplines.

Now based in Canada, Dr. Ebhuoma serves as the Data Distribution Lead at the Government of Alberta’s Provincial Geospatial Centre. In this role, he provides strategic leadership in the use and distribution of geospatial data across Alberta. He oversees complex projects that coordinate people, technologies, and processes to ensure spatial data is leveraged as a vital enterprise asset for governance and planning. His contributions to data sharing policies, GIS standards, metadata practices, and stakeholder engagement are helping reshape how spatial data is managed and distributed in Canada.

But it is his groundbreaking research in Africa that has captured international attention. In a recent study published in Geospatial Health, Dr. Ebhuoma and his co-authors Prof. Michael Gebreslasie, Oswaldo C. Villena, and Ali Arab employed a Bayesian spatial and spatio-temporal modeling framework to assess malaria risk in KwaZulu-Natal, South Africa. The model combined satellite-derived environmental data with local health records to generate high-resolution risk maps that highlight where malaria outbreaks are most likely to occur, often weeks in advance of confirmed cases.

By integrating remote sensing data on temperature, precipitation, vegetation cover, and land use with health surveillance data, Dr. Ebhuoma’s team was able to capture critical patterns of disease transmission across space and time. The study’s capacity to forecast malaria hotspots, even in areas with limited historical health data, represents a major breakthrough in proactive public health response.

“This research marks a shift from reactive disease control to anticipatory action,” Dr. Ebhuoma explained. “We are no longer waiting for outbreaks to spiral before acting. With the right tools and cross-disciplinary collaboration, we can predict, prevent, and respond before lives are lost.” His words reflect a growing consensus in global health: precision forecasting through data integration can save lives.

Beyond malaria, Dr. Ebhuoma’s approach is scalable and adaptable. His framework can be applied to other vector-borne diseases like dengue fever in urban slums, yellow fever in tropical corridors, or schistosomiasis in freshwater zones. As climate change continues to alter the habitat and behaviour of disease-carrying vectors, the need for flexible, data-driven public health models becomes even more urgent.

Dr. Ebhuoma’s career reflects his enduring commitment to this mission. Between 2014 and 2020, he researched, lectured and mentored students in GIS and remote sensing at the University of KwaZulu-Natal. His research during this period included malaria modelling and soil erosion modeling using geospatial tools and machine learning in South Africa. These projects deepened his understanding of geospatial intelligence, environmental science, public health, data analytics, environmental change, land use and community vulnerability.

His technical proficiency is equally impressive. He is fluent in spatial technologies such as ArcGIS, QGIS, Erdas Imagine, and TerrSet. He also brings programming skills in Python, JavaScript, SQL, R, and Power BI to data management and visualization. These tools allow him to automate data pipelines, enhance data accuracy, and develop visual dashboards that decision-makers can use in real time.

Dr. Ebhuoma is also certified in project management, holding a PMP qualification, and has completed specialized training in synthetic aperture radar (SAR) remote sensing. His strong grasp of environmental management and health regulations backed by NEBOSH certifications from the UK further underscores his holistic approach to development and risk mitigation.

As a scholar, his publication record is robust. He has co-authored peer-reviewed papers on topics ranging from soil erosion risk assessment using random forest algorithms to the socio-economic predictors of malaria transmission in South Africa. Each study reveals his ability to fuse rigorous academic research with real-world relevance and policy impact.
