Already during my school years I was fascinated to stare at the sky and became interested in learning more about the dynamics of the atmosphere and the weather. In October 2013, I started studying meteorology at the Karlsruhe Institute of Technology (KIT) and investigated the dynamics of a dust storm on the Arabian Peninsula in spring 2015 in my Bachelor's thesis. Two years later, I systematically evaluated the influence of El Niño on precipitation variability in Australia from a weather system perspective as part of my Master's thesis.

As part of the Collaborative Research Center/Transregional Waves to Weather, I am currently working in Project A8 ("Dynamics and predictability of blocked regimes in the Atlantic-European region") on a systematic evaluation of the underlying dynamics of large-scale flow patterns (so-called "weather regimes") over the North Atlantic-European region. For this purpose, I have developed a quasi-Lagrangian perspective in the framework of my PhD thesis that allows to trace circulation anomalies in their life cycle and to quantify the contribution of dry and moist processes in the evolution of large-scale weather regimes.

My research focuses on (i) large-scale dynamics with a focus on extratropical circulation patterns, (ii) synoptic meteorology with a focus on weather systems, and (iii) the influence of tropical modes such as the El Nino Southern Oscillation (ENSO) and Madden-Julian Oscillation (MJO) on the extratropical circulation.
