Academic Profile

I joined the Department in 2008 and currently serve as Coordinator of Atmospheric Science Programme. At undergraduate level, I teach climate module in Physical Environment (EGS2013F) and convene Atmospheric Science (EGS312S). At postgraduate level, I convene Research Methods for Physical Science (EGS4023F) and Climate Modelling (EGS4024S).

Research Interest

My research interest is in development, evaluation, and application of dynamic atmospheric models. I work with various types of atmospheric models (i.e. boundary layer models, meso-scale models, regional climate models, global climate models, and air pollution models), but focus on a model that has capability for horizontal grid adaptation (called CAM-EULAG). I evaluate atmospheric models and use them to study atmospheric systems (or conditions) that induce extreme events (like droughts, extreme rainfall, heat waves, and air-pollution episodes) in Africa. I also apply these models for predicting seasonal climates, projecting future climates under different emission scenarios, and understanding potential impacts of land-cover changes on regional climates.
