Teaching
- Research Integrity (2026)
The course aims to provide doctoral students with a foundational understanding of research integrity, promoting awareness of ethical principles, good scientific practices, and responsible conduct across all stages of the research process. - Psychometrics for Consumer Science (2025 – 2026)
This advanced course equips postgraduate students with methodological and applied skills to measure latent constructs shaping consumer preferences, with a special focus on the agrifood sector. - Monday Lab (2025 – 2026)
The laboratory offers graduate students a practical extension of the Marketing & Consumer Science course, combining theory with real-world applications. Through teamwork and RPGs, students apply concepts such as market research, consumer analysis, strategy development, and communication planning to real-world scenarios.
