- To help our client a major international product retailer to deal with demand peaks, I have build a time series machine learning model with scikit-learn to forecast demand, build a neural network to predict peak vs non peaks with python keras. - For a major pharmaceutical company I have developed a data pipeline with R to estimate lead times based on business rules from a lab sheduling system. I have gathered the requirements directly at the client and presented the outcomes of the analysis.

Research Assistant for Prof. Dr. Iris Kesternich, I assisted in an empirical project that analyses the effects of job stability on marriage stability based on cross-national microeconomic panel database with socio-economic indicators and health information. I helped preparing working papers for publication. Further, I prepared lecture slides on ’Policy Evaluation in Economics’.

I analysed documents provided by the European Commission, European Council and European Parliament.

I assisted in a research project on Growth-Enhancing Expenditure in EU Cohesion Spending from 2007 to 2013. I analysed the contributions of projects funded by the EU cohesion fund to future economic growth in the Slovak Republic.
