Practical data-centric optimization of C/C++ applications
(2022)C is a programming language used everywhere and in a big part of scientific codes. With the increase of highly parallel computing machines the code needs to be adapted to be able to use the full power available. In my thesis I will expand a compiler frontend to be able to transform C code into a data centric representation that will intern be able to identify data dependencies automatically and hence produce highly parallel code. ...Bachelor Thesis -
Experimental quantification of deadwood influence on rockfall dynamics and its incorporation into regional-scale rockfall models
(2022)Mountain forests provide an essential protective function against natural hazards. Various studies predict higher tree mortality and susceptibility to natural disturbances such as windthrow, bark beetle infestation, and forest fires as a result of future climate and legacies of land-use history. Therefore the fundamental research question of this thesis arises: Can disturbed mountain forests with lying deadwood still protect against ...Doctoral Thesis -

The flora of daylighted urban streams and their banks in the city of Zurich
(2022)As a result of habitat loss and increasing habitat fragmentation, biodiversity is under pressure worldwide. To conserve biodiversity in a sustainable manner, measures are needed that combine the human life with nature. One such effort is to employ blue-green infrastructure (BGI) in cities, which are networks of elements such as vegetated basins, green roofs, or urban streams. The city of Zurich is a pioneer in urban stream daylighting, ...Master Thesis -
From Ferroelectricity to Quantum Paraelectricity — Evolution and Doping from First Principles
(2022)Quantum paraelectric materials like SrTiO3 and KTaO3 exhibit many unusual material properties arising from their quantum fluctuations, including a high dielectric constant and unconventional uperconductivity. In combination with other unusual properties like strong spin orbit coupling and charged ionic layers in KTaO3, this leads to the observation of various intriguing phenomena. The primary goal of this thesis is to investigate these ...Doctoral Thesis -
Metapopulation dynamics and the influence of the killer system in a natural S. cerevisiae population
(2022)Populations and their genetic makeup are ever changing. Metapopulations of interconnected small populations, observed over many years, can give us an insight into large-scale shifts in their genetic composition. Here we use a natural metapopulation of Saccharomyces cerevisiae to explore changes in its genetic composition over time. We further examine a possible cause for genetic shifts using the killer-yeast system. We found a large ...Bachelor Thesis
