CV

Biography

Hello! I am a PhD Student (2024–2028) in Economics at Copenhagen Business School.

My research sits at the intersection of AI, labor, and innovation. I ask how people live and how they can live better: how work shapes wellbeing, and how technological change—from patents to large language models—reshapes the opportunities workers have. I answer these questions with Danish register microdata and LLM-based measurement tools.
