Time-scale synchronisation of oscillatory responses can lead to non-monotonous R-tipping

Published in Scientific reports, 2023

This paper showcases examples of nonlinear oscillators where the synchronisation of different oscillatory responses can lead to non-monotonic rate-induced tipping.

FastIsostasy v1.0 – An accelerated, regional 2D GIA model accounting for the lateral variability of the solid Earth

Published in Geoscientific model development, 2023

This paper describes the development of FastIsostasy, a model of glacial isostatic adjustment tailored to the needs of ice-sheet modellers who want a better representation of the deformational and gravitational response of the laterally-variable solid Earth to changes in surface load.

Is West-Antarctica’s Tipping Point a Fixed Value?

Published:

The tipping point of a tipping element is often referring to its bifurcation point. For instance, publications mentioning the tipping point of the West-Antarctic Ice Sheet (Lenton et al. 2008, Armstrong McKay et al. 2022) refer to the level of regional warming at which a large scale collapse arises in quasi-equilibrium simulations. This however omits the role of the forcing rate, which can imply a collapse at lower levels of regional warming, as I show through various simualtions. This effect is commonly known as rate-induced tipping and needs to be assessed when talking about a tipping point which, to answer the question, cannot be understood as a single value (unlike a bifurcation point).

Mechanics I & II for engineers - Teaching assistent

Undergraduate course, Technical University of Berlin, Institute of Mechanics, 2018

During a year and a half, I was teaching mechanics I (static and strength of materials) and mechanics II (kinematics and dynamics) for engineers at the TU Berlin.

Supervising Bachelor’s theses

Supervision, Complutense University of Madrid, Department of Earth science and Astrophysics, 2022

Since September 2022, I am co-supervising two bachelor’s theses per year at the Complutense University of Madrid. By using deep learning, the students have to perform an early detection of a West-Antarctic collapse and document their result.
