I (he/him) am a postdocoral researcher at the Chair of Geoinformatics at the Technical University Dresden and at the Spatio-temporal Modelling Lab at the 📍 Institute for Geoinformatics (ifgi) at the 🏫 University of Münster. I'm working on projects to make research in 🗺️ geography, 🌍🌏🌎 geosciences, and 🗺️❤️💻 GIScience more open, reproducible, and accessible. I think about both 🗃️💿 data and 🧑‍💻 software to achieve that. I strive to adhere to 👐 Open Science principles and 📢 advocate for open reproducible research.

• 🌍 NFDI4Earth addresses digital needs of Earth System Sciences in the German national research data infrastructure (NFDI) [2022-08 - ..]
• 🟩 CODECHECK is an open community that introduces minimalistic yet effective code execution practices into peer review processes to make science more transparent and reproducible. [Co-PI; 2019- ..]
• In the BMBF-funded project ⏫ OPTIMETA we strengthen the Open Access publishing system through open citations and spatiotemporal metadata by developing plugins for 📄 Open Journal Systems (OJS). [PI; 2021-08 - 2022-12]
• In the DFG-funded project 🔭 Opening Reproducible Research (o2r) we developed tools for increasing reproducibility of computational workflows in based on ✨ research compendia. [2016-01 - 2022-08]

I am interested in 🤔 improving the scholarly 📃 publication and 👯 communication process with new 🚀 information technology — of course with ⚡ Open Source software! I completed my 🧑‍🎓 PhD Infrastructures and Practices for Reproducible Research in Geography, Geosciences, and GIScience in 2022. My publications, CV, memberships, and service are in my 🟢 ORCID profile. Before academia, I worked as a consultant and research software engineer at 52°North Spatial Information Research GmbH. Because reserach doesn't work without software anymore, I am vice chair of the German association of research software engineers (de-RSE) and am a self-identifying RSE.

I enjoy playing 🥏 Ultimate Frisbee — the greatest sport ever invented by man.
