Research Interests

I am a river catchment scientist with a strong focus on rivers; their dynamics and human impacts on river catchments, extreme events and reach-scale classifications. I started out focusing on headwater streams and smaller catchments, however, in recent times I have been involved in large rivers, especially the River Niger. My aim regarding river dynamics and sensing is to understand the interactions between process and form on one hand and how these interactions can be predicted using a combination of field-based measurements, Earth Observations and machine learning algorithms. In addition, I interrogate the role of extreme events (such as floods, and drought) and human activities on basin hydro-geomorphology and their impacts on the river ecosystem. In essence, I am not only concerned with the dynamics of these rivers nor do I focus solely on extreme events but I assess the overall impact of combined pressures (such as anthropogenic activities, and changing climate) on rivers and their catchments using a combination of field measurements, historical analysis, models, statistical and geospatial techniques.

In all, the goal is to make rivers healthy to provide basic ecosystem services. I intend to provide my students not only with concepts surrounding basic fluvial systems but with problem-driven research designs that can provide solutions to catchment-wide challenges across space using state-of-the-art and emerging techniques. The goal is to ensure that my students have what it takes to proffer solutions to (re)emerging environmental problems.
