Biography
Katrin Kaltenegger works in the Pollution Management Research Group of the IIASA Energy, Climate and Environment Program.She holds a PhD from the University of Applied Life Sciences (BOKU), Vienna, as well as master's and bachelor’s degrees in Environmental System Sciences with a focus on Natural Sciences and Physics respectively, from the University of Graz. She discovered her passion for transdisciplinary work and modeling while writing her bachelor's and master's theses, which ultimately brought her to IIASA in 2018. In her PhD thesis she has expanded her work on nitrogen to also include social aspects that highlight the bidirectional influence of society and nature.
At IIASA, she focuses on various aspects of the nitrogen cycle and agricultural emissions. She was involved in a variety of projects, for example, combining a biomass model with the GAINS model; modeling nitrogen flows in urban areas; analyzing and updating EU member states' current policies on agricultural emissions using the GAINS model; and modeling the non-linear response of N2O emissions on nitrogen input to soil surfaces.
