Cosmos Senyo Wemegah (PhD.) is an Atmospheric and Climate Science Research Fellow at the Earth Observation Research and Innovation Centre (EORIC) and an Affiliate Lecturer in the Department of Atmospheric and Climate Science. He holds a PhD in Meteorology and Climate Science and works at the intersection of urban climatology, atmospheric physics, and applied climate risk assessment.

His research examines how urbanisation, emissions and climate change combine to shape health risks and energy demand in West African cities, with particular emphasis on heatwave resilience, urban heat islands and air pollution.

Over the past years, he has developed a programme of work on land-atmosphere interactions and urban climate dynamics, using observational networks, remote sensing, GIS and statistical programming to analyse extreme events such as heatwaves and floods in rapidly urbanising contexts. Cosmos translates empirical findings into predictive frameworks and operational early warning systems that integrate environmental drivers with socio-demographic vulnerability. His work informs municipal planning and public health practice by providing actionable decision support tailored to local exposure and adaptive capacity.

In teaching, he supervises graduate research and delivers courses in urban climatology, atmospheric measurement and analysis using R, Python, and FORTRAN, and climate risk modelling, emphasising practical skills in Earth observation and data analysis. He is also a strong advocate for citizen science, co‑designing community air quality monitoring and heatwave alert tools that empower residents to generate local data and participate in resilience planning.
