Adapting climate science
(2020)Much scholarship has argued that information on future climate change ought to be the basis for climate adaptation decisions. But how has the impressive corpus of knowledge produced by climate scientists been processed and adapted to inform adaptation decisions in practice? This doctoral thesis compares and analyses how different actors have ap-proached, grappled with, understood, generated relevance and acted upon climate science for ...Doctoral Thesis -
Exploring topographic and scaling properties of landscapes by dimensionally analyzing stream-power incision and linear diffusion landscape evolution models
(2020)In this PhD project, I dimensionally analyzed a frequently used landscape evolution model (LEM) and I derived geomorphological interpretations of the characteristic scales and dimensionless numbers that were revealed by the analysis. I studied an LEM with terms of stream-power incision, linear diffusion, and uniform uplift, parameterized by an incision coefficient K, a diffusion coefficient D, and an uplift rate U, respectively. ...Doctoral Thesis -
Numerical approximation methods for high-dimensional partial differential equations of second order
(2020)Classical numerical approximation methods for partial differential equations typically suffer from the so-called curse of dimensionality. This means that the computational effort for calculating an approximation of a desired approximation accuracy grows exponentially in the dimension of the partial differential equation. The present thesis deals with different approximation methods for several classes of partial differential equations ...Doctoral Thesis -
Change in Conceptual Understanding: The Role of Learning Opportunities, Prior Knowledge, and Intelligence
(2021)The aim of this doctoral dissertation is to grasp the effect of prior knowledge to future learning as well as the relation between cognitive abilities and prior knowledge in physics within the framework of conceptual change. For this purpose, I conducted two studies, which are described in four empirical articles. The first study dealt with the impact of domain-specific prior knowledge in mathematics and physics as well as cognitive ...Doctoral Thesis -
The overlooked pathway: Hydraulic shortcuts and their influence on pesticide transport in agricultural areas
(2022)Introduction. Pesticides used in agriculture are transported to surface waters through various pathways and pose a major threat to aquatic ecosystems. Farmers and authorities take various measures to reduce pesticide transport to surface waters and to protect them from harmful effects. However, such actions can only be effective if the underlying processes driving the pesticide risk are understood well enough. Previous research suggests ...Doctoral Thesis -

Monitoring of Ice Nucleating Particles (INP) at the Jungfraujoch: Automation of the Horizontal Ice Nucleation Chamber for Continuous INP Monitoring
(2021)The presence of the ice phase within clouds alters relevant quantities to Earth's weather and climate. How aerosols interact with clouds contributes to one of the largest uncertainty within current climate projections. Ice nucleating particles (INPs) are a special subset of aerosols that can aid the phase transition of cloud droplets to ice crystals. As only a tiny fraction of all atmospheric particles have the ability to act as INPs, ...Doctoral Thesis
