Geoffrey Blewitt (IAG)

Geoffrey Blewitt is a professor at the University of Nevada, Reno, USA, at both the Nevada Bureau of Mines and Geology, and the Department of Physics.  Dr. Blewitt’s research focuses on geodesy, reference frames, techniques for very high precision GPS and its application to Earth sciences including plate tectonics, earthquake cycle, surface mass loading, glacial isostatic adjustment, sea-level change, and atmospheric science. He also uses atomic clock data of the GPS satellites to search for new exotic physics, including galactic dark matter and low-mass fields emanating from black hole merger events.  His career started at the NASA Jet Propulsion Laboratory, as a leading developer of the GIPSY-OASIS software for millimeter-precise positioning with GPS data using patented techniques.   He founded and now runs the Nevada Geodetic Laboratory which processes data from all available geodetic GPS data in the world acquired since 1994, currently from over 18,000 stations.  His refereed publications have been cited over 15,000 times, recently averaging over 1,000 citations per year.  Dr. Blewitt’s research contributions earned him the Vening Meinesz Medal from the European Geosciences Union, and multiple NASA awards. He is a Fellow of the American Geophysical Union and of the International Association of Geodesy. Dr. Blewitt has served as President of IAG Commission 1 on Reference Frames, as President of the American Geophysical Union Geodesy Section, and as a member of two U.S. National Academies Committees. He earned his Ph.D. in physics from the California Institute of Technology.

Max Moorkamp (IAGA)

Max Moorkamp is currently a Heisenberg Junior Research Group Leader at the University of Munich. His research focuses on combining different types of geophysical data to obtain better images of the subsurface of the Earth. In particular, he uses electromagnetic measurements in conjunction with seismology, gravity and magnetics to understand the composition and processes in the crust and upper mantle. He received his Diploma in Geophysics from the University of Goettingen. For his PhD he moved to the Dublin Institute for Advanced Studies, Ireland and developed a new joint inversion approach for magnetotellurics and seismic receiver functions. He received his PhD in 2007 from the National University of Ireland, Galway and joined Geomar, Kiel for postdoctoral position in the industry funded JIBA project. During this time he started developing a 3D joint inversion framework. jif3D, which has formed the basis of his further research and is now used by a variety of research groups worldwide. In 2011 he moved to the University of Leicester as a Lecturer in Geophysics and continued to work on new methods of geophysical data integration. Since 2018 he is working at the University of Munich as part of the German Science Foundation Funded Heisenberg Program. The focus of his work there is to adapt machine learning and medical imaging techniques to geophysical inverse problems.

Luz Adriana Cuartas (IAHS)

Luz Adriana Cuartas is, since 2014, a scientist in hydrology at the Brazilian National Center for Monitoring and Early Warning of Natural Disasters – CEMADEN and Visiting Researcher at the Division of Water Resources, Lund University since August 2022. She holds a Civil Engineer degree and a Water Resources MSc from the National University of Colombia, and a Meteorology PhD from the Brazilian National Institute for Space Research (INPE) – University of Campinas. She worked at INPE, in the Earth System Science Center – CCST as a hydrology and hydro-meteorology scientist (2008-2014), where she is also a professor at the PhD Program in Earth System Science PGCST/INPE. Since 2020, she is also a professor at the Graduate Program in Natural Disasters CEMADEN – UNESP. She has participated in projects and consulting activities on hydrology, hydrometeorology, biosphere-atmosphere interactions, and the impact of land use and climate change on water resources, with observational studies and hydrological modeling of micro, meso and macro scale catchments. She has participated in collective interest educational outreach programs through short courses on hydrology, climate change and modeling, offered in Brazil and abroad. She is a key co-author of a revolutionary Normalized Terrain Model HAND (Height Above the Nearest Drainage), which can be applied in mapping water soil conditions and predicting the potential depth of the water table across the landscape and also the potential flood extent using only digital topography. She developed and applied new approaches for hydrological modeling in the prediction of hydrological scenarios in basins under risk of water scarcity. Adriana is working on the understanding and assessment of Hydrological drought at different spatial and temporal scales, and how it could impact hydropower generation in Brazil.
