“Every map ever drawn. Every satellite ever launched. Every border ever defined. All rest upon one science… Geodesy” About the Event What if the science that holds our modern world together remains largely invisible to those who…

Meet Yuting Cheng – Early Career Scientist

, , ,
Yuting is a postdoctoral researcher at the Royal Observatory of Belgium working on the ambitious ESA GENESIS project. Her research centers on a unique satellite co-locating all four space geodetic techniques, creating a unified reference point in space. Her work contributes to improving the precision and stability of the International Terrestrial Reference Frame, while exploring how these observation systems perform together under novel space conditions.

Meet Julia Pfeffer – Early Career Scientist

, , ,
Julia Pfeffer is a French research engineer specializing in monitoring the global water cycle through satellite geodetic measurements. Since 2020, she has led satellite gravimetry activities at Magellium and currently heads major ESA and CNES projects. With a PhD in Geophysics, she has contributed to GRACE solutions, developed key geodetic datasets, and authored over 25 scientific publications.
