When only counting the directly assigned grants, the total amount of funding from the last ten years was about 6,000 T€. When including the institutional and departmental responsibilities, it was more than 25,000 T€.
Special completed grants were the contribution to the cluster QUEST (Quantum Engineering and Space-Time Research) within the German Excellence strategy, 2009 to 2014, with total funds of about 34,700 T€. Another major project was the DFG Research unit FOR 584 “Earth rotation and global dynamic processes“ (2006 – 2014) with a total amount of about 4,600 T€.
A major ongoing grant is the DFG CRC 1128 geo-Q (2014 – 2019) which was funded with 11,500 T€ in the first 4-year funding period. I am spokesperson of that CRC and PI of 3 projects.
Recently, we applied for a research cluster within the German Excellence initiative, Quantum Frontiers (total funds 57,000 T€, planned duration 2019 – 2025). I am Co-PI together with 24 colleagues.
Overall more than 150 refereed publications, about 100 in the past 10 years. They have been cited more than 1100 times in the past 5 years; h-index = 23 (google scholar).
We run one of only 4 LLR (Lunar Laser Ranging) analysis centers worldwide. Our group is leading in testing general relativity using LLR data. Its estimated limits for a possible temporal variation of the gravitational constant and the validity of the strong equivalence principle are world record.
Besides those LLR-related activities, close collaboration with physics has been established in the past 10 years to develop novel concepts for geodetic applications, especially for gravity field observations. These comprise the application of atomic interferometry for gravimetric measurements, the use of laser interferometry for inter-satellite tracking (satellite mission GRACE-FO was launched in May 2018) and the use of highly accurate optical clocks to determine the Earth geopotential (keyword “relativistic geodesy”).
