Yosuke Aoki received his Ph.D. degree from the University of Tokyo in 2001. He was then a Lamont Postdoctoral Fellow at Lamont-Doherty Earth Observatory of Columbia University between 2001 and 2003. He took a faculty position at Earthquake Research Institute in 2003 and has been there since then. His primary expertise is observing and modeling the deformation of the Earth’s surface associated with seismic and volcanic activity mainly from space geodetic techniques such as GNSS and SAR. For example, he has revealed the magma plumbing system of active volcanoes by combining geodetic data with independent information such as seismic and electromagnetic observations and petrological insights. He is also interested in technical developments to extract hidden information in the data and to gain insights into the mechanics of earthquakes and volcanic activity. He has published more than 60 peer-reviewed articles during his career. Corné Kreemer received his Ph.D. degree from Stony Brook University in 2001. He was a postdoctoral fellow until 2004 at the Ecole Normale Superieure, Paris, and the College de France. Since 2004 he is an academic member of the Nevada Geodetic Laboratory in the Nevada Bureau of Mines and Geology at the University of Nevada, Reno. He also has a joint position at Nevada Seismological Laboratory. His primary expertise is in converting GNSS-derived crustal velocities into strain rate and vertical land motion models and relating those results to earthquake occurrence and lithosphere and mantle dynamics. He has also worked on reference frame definitions, several earthquakes, tsunami early warning, and time-series analysis techniques. He is best known as the main contributor to the Global Strain Rate Model. He has published over 75 peer-reviewed articles.
