Dr. Adam Amir

Spencer Biogeochemistry Lab, Postdoc researcher

I am a filmmaker with an interdisciplinary background including philosophy, political ecology, science communication, and feminist methodologies. For my research I use collaborative methods, particularly "Folk Filmmaking", a form of participatory video production that helps local communities express their environmental values and concerns through storytelling. My work focuses on cross-cultural, moral debates over environmental issues and explores how collaborative filmmaking can help foster contextual, respectful adjudication. I conducted Folk Filmmaking projects in Nigeria, Cameroon, Kyrgyzstan, and Tajikistan, and shared the methods while assisting productions with the Hualapai and Navajo Nations. With the Spencer Lab I am working in the Congo River Basin and refining Folk Filmmaking as a method for communicating environmental issues through respectful, cross-cultural media production.

Dr. Matti Barthel

ETH - Sustainable Agroecosystems, Research technician

After graduating in ecology and working as a scientist in the field of biogeochemistry and plant ecophysiology, I switched my focus to the analytical side of research mainly working on the analysis of N2O isotopocules using laser and mass spectrometry. My general research interest focusses on the biogeochemical cycling of C and N across different ecosystems. Within this broad framework, I am particularly interested in aquatic and terrestrial greenhouse gas exchange using micrometeorological and stable isotope methods.  In the Congo Basin, we aim to quantify nitrous oxide emissions across various tropical forest types as tropical forests, in general, are believed to be the main natural source of nitrous oxide.

 

Dr. Travis Drake

ETH - Sustainable Agroecosystems, Postdoc researcher

My current research is focused on the effect of deforestation and agriculture on carbon mobilization in watersheds of eastern Democratic Republic of the Congo. To accomplish this, I use a variety of analytical tools to characterize both organic and inorganic carbon in streams draining pristine and impacted catchments. These include stable and radiocarbon isotopes, FT-ICR mass spectrometry, fluorescence, uv-visible absorbance, and bioincubations. With these tools I strive to link the isotopic signature of inorganic carbon with potential organic sources. Underpinning this research is an effort to improve methods of capturing whole watershed processes, since a growing body of work has highlighted headwaters as important vents for respired terrestrial carbon dioxide.

Benjamin Bukombe

Augsburg University, PhD student

I am an agricultural and soil scientist. I got my bachelor’s degree in soil and environment and my master’s degree in agricultural sciences with specialization on soils.  My previous researches have been focusing on integrated soil fertility management, digital soil mapping and remote sensing of the landscape.

I am currently a PhD student funded by the TropSOC project, at the Institute of Geography, Augsburg University. As part of project objectives, I am trying to understand the effects of erosion and geochemistry on nutrient cycles and biomass production in tropical forests and agroecosystems with much focus on carbon. I will assess carbon inputs patterns and release and the effects that change in soil conditions has on plant biomass allocation strategies across different geochemical systems of tropical Africa.

Laura Summerauer

ETH - Zurich, PhD student

For my Bachelor, I studied agricultural science at ETH Zurich, where I also completed my Master in crop science with a further focus on soil science. For the master thesis, I spent half a year in Djolu (Tshuapa Province, DRC) studying crop productivity and soil fertility under different agricultural managements in demonstration trials together with the International Institute of Tropical Agriculture (IITA) and local farmers. Furthermore, we were measuring soil N2O fluxes in primary and secondary forests and agricultural fields. Now I am creating a soil spectral library for the DRC using an ALPHA Fourier Transform Infrared (FT-IR) spectrometer, for simplifying soil analysis without expensive and time consuming wet chemistry. Creating an R interface, the analysis of the spectra will also get easier.

Simon Baumgartner

Catholic University of Louvain, PhD student

I studied Environmental Sciences at ETH in Zürich with a major in Biogeochemistry and Pollutant Dynamics.  I conducted my MSc thesis in the DRC, where I measured N2O fluxes and their isotopic composition across different forest types (Kahuzi-Biéga, Yoko and Yangambi). Because of this thesis, I got interested in the nutrient cycles of tropical forest ecosystems and the work in the DRC. My PhD is within the FORSEDCO-project at UCL in Louvain-la-Neuve. The goal of my work is to quantify particulate nutrient export (mainly nitrogen) in first-order streams because the availability of nutrients determines the productivity of forests and is an important factor controlling carbon sequestration. Furthermore, we want to assess the factors controlling these particulate losses due to erosion and its significance to the nutrient availability of tropical forests.

Laurent Kidinda

Dresden University of Technology, PhD student

I am an Agronomist Engineer with emphasis on soil weathering, carbon and nutrient cycling. I am a research associate in the framework of TropSOC (DFG funded (DFG funded Emmy Noether group) and I hold a scholarship from the German Academic Exchange Service (DAAD) to carry out my PhD research at Dresden University of Technology. My PhD research focuses on understanding if soil erosion in the eastern part of the Congo Basin is fast enough to reach the less weathered regolith, which contains the minerals with more reactive surfaces to stabilize carbon, while still allowing fast soil weathering and nutrient retention at a high level. Along geochemical and geomorphic gradients, I evaluate the effects of pedogenic oxides and clays minerals on carbon stabilization and release, as well as microbial processes related to C cycling (e.g. microbial biomass carbon, enzyme activities, Extracellular polymeric substances, and amino sugars).
