Research

I have pretty broad interests, and this is reflected in my research as well. This page provides a summary of the main topics of my recent work, my PhD and MSc theses, and provide a list of publications for reference.

Research topics

Atmospheric Chemistry

High-altitude emissions, such as from new aircraft concepts and spaceflight, have extensive effects on the composition of our stratosphere, the ozone layer, and climate. With my research I hope to improve our understanding of these effects, by using atmospheric chemistry transport models to facilitate extensive analyses of how the adoption of new and existing technologies affect our atmosphere.

Model discovery methods

Model discovery methods allow us to find simplified models to represent complex data. I apply these approaches to atmospheric chemistry data to assist with understanding these complex systems, and to build computationally efficient reduced-order models. The latter may be especially valuable to aid in decision-making processes, or for policy design, where more complex models cannot be used on the fly.

Machine learning

Machine learning methods also offer much promise for computationally efficient reduced-order models to aid in decision-making processes. Therefore, I also research the possibility of combining various machine learning methods with data from chemistry transport models for data analysis, interpretation, and surrogate modelling.

Spaceflight

Before my venture into atmospheric chemistry I worked on the optimization of satellite swarm orbit design, and inter-satellite ranging through interferometry, but my interests in the space domain extend further. In my PhD I also incorporated measurements from TROPOMI, and I’ve also had the chance to contribute to research of the atmospheric and climate effects of emissions of the modern spaceflight sector.

PhD Thesis

My PhD thesis is about the effect of high-altitude emissions from supersonic aircraft on the composition or our atmosphere, radiative forcing, and surrogate modelling methods thereof. More information about this work can be read on the dedicated summary page I’ll write later (once the thesis is done).

MSc Thesis:

My master’s thesis research tackles the use of genetic optimization algorithms for satellite constellation and orbit designs for the OLFAR satellite swarm for radio interferometry. A summary of my MSc thesis can be read here.
