I am a Master's student in Economics at the WiSo Faculty of the University of Cologne, specialising in Market Design and Behaviour.
Having completed my B.Sc. in Economics at Rheinische Friedrich-Wilhelms-Universität Bonn, I have a robust understanding of Quantitative Economics, Economic Policy, Companies and Financing and Markets and Strategies.
I wrote my Bachelor's Thesis, 'Comparison of Discriminant Analysis and Random Forests in Classification', at the Institute of Finance and Statistics (IFS).
Professionally, I've gained hands-on experience as an Office Manager at Christoph Osterhaus Heizung Sanitär, and I am now actively seeking Data Scientist internship opportunities to apply my quantitative and economic skills to solve real-world problems.
Combining econometrics and machine learning: I have a strong ability to combine traditional panel methods with modern machine learning approaches, such as random forests and hyperparameter tuning.
The module 'Using Data to Address Societal Challenges' (1.0), taught by Prof. Teodora Boneva Ph.D., was a pivotal experience in my studies at the University of Bonn. It motivated me to apply my data science expertise to issues where a series of individual micro-decisions result in significant societal challenges, such as the gender pay gap and a lack of intergenerational mobility.
