Description

PhD Economist (Dr. oec., magna cum laude) with 15+ years blending rigorous statistical analysis, advanced econometrics, and international project leadership across 25 countries. Fluent in German, English, and Spanish.

My edge is rare: I combine PhD-level econometrics (gravity models, fixed-effects panel regressions, causality testing) with hands-on data science in Python and direct experience delivering insights for C-suite and board-level decision-makers across 25 countries.

I don't just model. I understand what senior stakeholders need from data and deliver it in a language that convinces boards, investors, and funders.

What I do for clients

Advanced statistical analysis and econometrics: from market predictions to program evaluation to survey data
Causal inference and forecasting: where correlation is not enough and the methodology must be bulletproof
Quantitative trading strategy development: signal generation, backtesting, algorithmic strategy development in Python
AI output validation: ensuring AI-generated analyses, models, and research meet the standards required for investment, publication, and board-level decisions

Track record

International Project Leader, multinational company: Led cross-functional projects across 25 countries, conducted in-depth data analysis and benchmarking for board-level strategy and restructuring initiatives. References highlight “precise data analysis, strategic implementation, and outstanding stakeholder management.”
