Dániel Erdélyi is a Junior Research Fellow at the Paleoklíma 2ka Lendület Research Group at the HUN-REN Geological and Geochemistry Institute of the Research Centre for Astronomy and Earth Sciences, and a PhD candidate at the Faculty of Science of Eötvös Loránd University. His research focuses on the spatial modeling of stable and radioactive isotopes from precipitation on a subcontinental scale using geostatistical and machine learning methods. He has been a board member of the Geomathematics and Informatics Section of the Hungarian Geological Society since 2021 and a member of the Geomathematics Subcommittee of the Hungarian Academy of Sciences since 2023.

As an ARP ambassador, his goal is to participate in the development of a unified data management process that effectively supports the needs of researchers, facilitating the simple and accurate deposition of results. Additionally, he aims to actively participate in increasing the visibility of the ARP data repository and raising awareness among students and researchers about the importance of secure data storage.

In co-operation with István Hatvani, Dániel plans to deposit three significant datasets in the ARP repository: (1) decade-long time series of stable isotope data of Lake Balaton, (2) geochemical composition data tables of groundwater and surface waters from the O-WATCH project, and (3) cosmogenic isotope measurement data from Macedonia for quantifying surface development processes. István and Dániel work with joint commitment and expertise to promote the free accessibility of scientific data and the realization of Open Science principles.
