Immediate Past Secretary General
He has been the director of the Department of Geodesy and Geodynamics, Finnish Geospatial Research Institute (FGI), National Land Survey of Finland. He has been working in the FGI since 1985 on satellite geodesy and positioning, reference frames and metrology. Poutanen is the President of the Nordic Geodetic Commission, past president of EUREF, and European Geosciences Union (EGU) Geodesy Division.
Urs Hugentobler is a Professor for Satellite Geodesy in the School of Engineering and Design of Technical University of Munich and head of the Research Facility Satellite Geodesy, operating the Geodetic Observatory Wettzell jointly with the Federal Office of Cartography and Geodesy. He received his PhD degree in Astronomy in 1998 from University of Bern. He is member of Editorial Board of the Journal of Geodesy, Chair of ESA's GNSS Science Advisory Committee, and Secretary of the German Geodetic Commission of the Bavarian Academy of Science.
Rebekka Steffen is a researcher in geodesy at Lantmäteriet (The Swedish Mapping, Cadastral and Land Registration Authority). She is working on glacial isostatic adjustment (GIA) modelling with a focus on stress field changes and model development, analysis of static gravity fields in terms of crustal and lithospheric structures of the Earth and Moon, and is involved in the development of a European velocity model as part of EUREF (Regional Reference Frame IAG Sub-Commission for Europe). She received her PhD in 2013 from the University of Calgary. Rebekka has chaired a JSG within IAG commission 3 on GIA modelling and is an editor of the EGU Geodesy blog. She is also an adjunct professor at Dalhousie University in Canada. Personal website is available here.
ICC & COB Presidents, IAG Project Chair and Members at Large
Annette Eicker ist professor for geodesy and adjusment theory at HafenCity University Hamburg, Germany. Her research interests cover the use of satellite gravimetry data for studying the changing system Earth, focussing on the use of GRACE/GRACE-FO data for water cycle and climate studies. Since 2019 she has been president of the Inter-Commission Committe on "Geodesy for Climate Research" of IAG.
Szabolcs Rózsa is an associate professor at the Budapest University of Technology and Economics. He is the Head of the Department of Geodesy and Surveying. Since 2003 he has been the secratary of the IAG COB. His research area focuses on GNSS positioning and navigation, especially their application in atmospheric remote sensing.
IAG Project Chair
Novel Sensors and Quantum Technology for Geodesy
Jürgen Müller is full professor in physical geodesy at the Leibniz Universität Hannover, Germany. His research fields cover satellite geodesy, space and terrestrial gravimetry, including novel measurement concepts, related earth system research, lunar laser ranging and general relativity. In 2023, he has received the Vening Meinesz Medal of the EGU for his outstanding contribution to the advancement of modern geodesy.
Member at Large
Maria Virginia Mackern
Member at Large
Dr. Laura Sánchez is a research scientist at the Deutsches Geodätisches Forschungsinstitut (DGFI-TUM) of the Technische Universität München, Germany. Her research interests include vertical datum unification, global height reference systems, GNSS-based regional reference frames, and surface kinematics monitoring. She served as GGOS Vice-President for the period 2019-2023. She also led the GGOS Focus Area “Unified Height System” between 2015 and 2023, the main outcome of which was the establishment of the International Height Reference System (IHRS) and its realisation, the International Height Reference Frame (IHRF). From 2007 to 2015, she was Vice-President of the Geodetic Reference System for the Americas – SIRGAS, and since 2015, she has been a member of the SIRGAS Scientific Council. She is currently Assistant Editor-in-Chief of the IAG Symposia Series. She is an elected IAG Fellow and has been involved in several IAG working and study groups since the 2000s.
He is a Professor of Geophysics in the Department of Earth Atmospheric and Planetary Sciences. He joined the MIT faculty in 1989. His research interests are in the development and applications of precise geodetic techniques, primarily the Global Navigation Satellite Systems (GNSS), and Interferometric Synthetic Aperture Radar (InSAR), to study deformation processes on all spatial and temporal scales. He also uses these methods to study properties of the propagation medium including the Earth’s atmosphere. He has been awarded the Macelwane Medal by the AGU, the Bomford Prize by the IAG, and the Vening-Meinesz Medal by the EGU. He is a fellow of the AGU, the IAG and the American Association for the Advancement of Science.
