Why I love org-babel

A concept to a resilient future.

I am a passionate classical archaeologist with a PhD from Humboldt-Universität zu Berlin. After working as a Data Steward in two Collaborative Research Centers, I now serve as the Deputy Head of the "Research Process & Data Management" department at RWTH Aachen University’s IT Center. I blend my expertise in classical archaeology with research data management and interdisciplinarity to bridge the gap between theory and practical applications. In my current role, I take a **process-oriented and data-driven approach** to ensure seamless collaboration among researchers, data managers, and IT professionals.
