Research Interests

I am a river catchment scientist with a profound passion for unraveling the intricate dynamics of rivers and their susceptibility to human impacts. My journey in research commenced with a focus on headwater streams and smaller catchments, but I have since broadened my horizons to delve into the study of larger rivers, with a particular emphasis on the River Niger. My primary mission in river dynamics and sensing is to decipher the complex interplay between natural processes and the resulting formations while harnessing the predictive power of a harmonious fusion of field-based measurements, Earth Observations, and cutting-edge machine learning algorithms. Furthermore, I investigate the profound influence of extreme events such as floods, droughts, and human activities on the hydro-geomorphology of river basins and their repercussions for river ecosystems.

My work extends beyond the mere study of river dynamics and the analysis of extreme events. Instead, I aim to comprehend the holistic impact of combined pressures, encompassing anthropogenic activities and the evolving climate, on rivers and their surrounding catchments. To achieve this, I employ a comprehensive toolkit, which includes field measurements, historical analyses, models, statistical methodologies, and geospatial techniques. Ultimately, my overarching objective is to nurture the well-being of our rivers, ensuring they continue to provide essential ecosystem services. As an educator, I am deeply committed to imparting foundational knowledge of fluvial systems and equipping my students with problem-driven research methodologies that yield innovative solutions to catchment-wide challenges across diverse landscapes, utilizing state-of-the-art and emerging techniques. My goal is to empower the next generation of environmental scientists to effectively address both existing and emerging environmental issues, contributing to a sustainable future for our planet.
