Scientific career
2022 to present - Post Doctoral Researcher
- Linking soil erosion dynamics with identification of source areas and stratigraphic geochemical
sediment core analysis for deciphering the impact of land-use change in the watershed of a drinking water reservoir in Central Kenya.
- Design and operate a monitoring system of dynamics of suspended sediments in the reservoir.
- Sedimentological and geochemical features analysis (high-resolution magnetic susceptibility
connected to ITRAX-XRF core scanning, P fractions, lipid and sugar biomarkers).
- Establish sediment core chronologies (7Be;137Cs;210Pb)
- Compare modelled ages with micro-sedimentological information (i.e., flood event
markers).
- Connect sedimentology results with historic land-use information in the watershed (maps, aerial photographs, satellite imagery).
- Combine sediment data and historic land use data with information from plot-scale experimental studies and assessment of suspended sediment dynamics in the watershed to develop record of land-use change and impact on the reservoir.
2020 - 2021 - Late Quaternary Researcher - University of Lund
- Completed Holocene land-cover reconstructions from Europe and submit data to open database.
- Increased the resolution of the land-cover reconstructions to provide data to land-use modelers.
2018- 2020 - Post Doctoral Researcher - Linnaeus University
- Identified suitable pollen records from Europe and contact authors to share data.
- Compiled a European Holocene pollen database.
- Data clean-up and standardization.
- Holocene land-cover reconstructions covering Europe.
2013 - 2016 - Marie-Curie Early Stage Researcher - University of York
- Developed a research project looking into environmental histories of different East African landscapes, logistical support and supervision during the duration of the project.
Trained and supervised lab work done by undergraduate
2012 - 2013 Research Intern National - Museums of Kenya
- Microfossil analysis – pollen, charcoal, non-pollen palynomorphs.
- Data analysis and interpretation.
Providing support on field expeditions
I am an ecological researcher focusing on the analysis of land-cover and land-use to understand environmental change at multiple spatial and temporal scales. I am currently working on a DFG funded project “Linking soil erosion dynamics with identification of source areas and stratigraphic-geochemical sediment core analysis for deciphering the impact of land-use change in the watershed of a drinking water reservoir in Central Kenya”. The DFG funded project will identify the sources of sediment and associated loads to Ruiru reservoir located in a typical rural landscape in the uplands of Central Kenya. We want to understand both the driving processes and spatio-temporal dynamics of soil erosion and sediment transport from the watershed to the water body and its sedimentary sink.
