Post Doctoral Research Fellow

School of Geography, Earth and Environmental Sciences (Faculty of Science and Engineering)

I am a postdoctoral research fellow and river catchments consultant specialising in assessment of catchment soil erosion and downstream water quality. I am currently involved in interdisciplinary research as part of the Jali Ardhi (Care for the Land) project focussing upon sustainable land management in Tanzania. I am also a member of the Catchment & River Applied Research (CaRAR) team, providing environmental diagnostics services for a range of stakeholders across the UK.
