PhD students

• Turry Ouma carried out her PhD thesis as part of the N2O-SSA project. She successfully defended her thesis "Nitrous Oxide Emissions Accounting in Sub-Saharan Africa: Regional Patterns, Isotopologue-Based Pathway Partitioning, and Process-Resolved Field Evidence from Kenya" in June 2026 and was awarded her PhD at ETHZ. Congratulations Turry!
