I am a Master's student in Economics at the University of Cologne , specialising in Market Design and Behaviour. There my work focuses on the intersection of behavioural economics and applied economic policy
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.
What's New? I am currently working on my Exposé for my Master's Thesis, which will focus on behavioural Economics, Applied Micro und EU-Policy. In particular, I aim to study how behavioural biases shape individual and institutional decision‑making in the European policy context, and how evidence-based interventions can improve policy design and effectiveness.
Additional to that I am currently seeking opportunities as a Economic Advisory intern.
Profile
I am a Master's student in Economics at the University of Cologne, specialising in Market Design and Behaviour.
My Bachelor's Thesis, 'Comparison of Discriminant Analysis and Random Forests in Classification' compares Linear Discriminant Analysis, Quadratic Discriminant Analysis, and Random Forests to evaluate their suitability for binary classification tasks, with a particular focus on predicting diabetes status from physiological and demographic data.
Motivation
I am particularly interested in applying data science to societal challenges where individual decisions aggregate into large-scale outcomes, such as inequality and economic mobility.
My academic experience has strengthened my interest in bridging rigorous economic theory with practical, data-driven approaches. Access to my recent projects will soon be available via GitHub. I am using GitHub as a version control system to make my work reproducible.
Technical Skills
- Programming and Data Analysis: R (tidyverse, caret, randomForest), Python (pandas)
- Methods and Modelling: Classification (Decision trees, Random Forests), cross-validation, hyperparameter tuning, model evaluation (ROC/AUC, F1), econometrics
- Business Tools: LaTeX, MS Office, DATEV, CRM/ERP systems
- Visualization: Basic Power BI
Professional Experience
I have gained practical experience as an Office Manager at a mid-sized company, where I was involved in administrative processes and ERP system implementation.
Currently, I am seeking opportunities as a Economic Advisory intern to apply my quantitative and analytical skills to real-world problems.
