Publications

While studying for my Masters and my PhD at the University of Zurich, Switzerland, and working as a research assistant and being a visiting scholar at the University of Oxford, UK, I have (co-)published several articles in academic outlets. Topics range from geodata, 3D data and geomorphometry to crowdsourcing and the digital divide. After my academic work, I continue to (co-)author technical reports on behalf of clients and occasionally abstracts for conferences. The former are only rarely made publicly available.

Except where noted, below publications have been refereed.
