Jie JIANG

Prof. Dr. Jie Jiang received her BSc. and MSc. degrees in Applied Geophysics from the Changchun University of Geology, China, in 1985 and 1988, respectively. In 2000, she completed her research study at China University of Mining and Technology (Beijing) and obtained her PhD in Surveying Engineering. She had worked as a remote sensing and GIS specialist in the Municipal Urban Planning and Management Information Center of Changzhou from 1989 to 1999. From 2000 to 2018, she had worked in the National Geomatics Center of China (NGCC) as a Senior Engineer and Division Director. During her time at NGCC, she had been in charge of many national-level projects on remote sensing and GIS applications, among them the most important ones included the National Platform for Geoinformation Services, Global Mapping with Chinese Satellite Images, the National Geodatabases for E-government, and the National Databases for In-car Navigation. Since October 2018, she has worked as full professor in School of Geomatics and Urban Spatial Informatics, executive dean in International Development Research Institute, Beijing University of Civil Engineering and Architecture (BUCEA).
She has served as the ISPRS officer since 1998. She is now ISPRS Fellow, and the Vice President of the ISPRS TC III on remote sensing (2016-2021). She got the National Science and Technology Progress Award of China (2nd prize) in 2016, and more than 10 Science and Technology Progress Awards from Ministry level. She got the ISPRS President’s Citations in 2012, ISPRS The Eduard Dolezal Award in 2004.

John L. LaBrecque

John L. LaBrecque is a Fellow of the International Association of Geodesy, Chair of the IUGG GeoRisk Commission and leads the Geohazards Monitoring Focus Area of the Global Geodetic Observing System. John LaBrecque is a 1977 graduate of Columbia University and a former senior research scientist of Columbia’s Lamont-Doherty Earth Observatory where he conducted geophysical research in global tectonic evolution and geopotential fields using ocean surveying and drilling ships, aircraft, and satellites including the early evaluation of GPS for geophysical research. In 1993, Dr. LaBrecque joined NASA’s Solid Earth Program where he encouraged the development of ground and spaceborne GNSS applications for environmental and geohazards measurement. Dr. LaBrecque served as program scientist for several NASA missions including the Shuttle Radar Topography Mission, the GRACE gravity missions, and numerous international GPS occultation missions including SAC-C, CHAMP, Oersted, and COSMIC. Dr. LaBrecque is the 2009 recipient of the Golden Medal of Merit from the Institute of Applied Astronomy of the Russian Academy of Sciences, and the 2013 recipient of the American Geophysical Union’s Edward A. Flinn III Award. Dr. LaBrecque retired from NASA in May, 2014. Dr. LaBrecque has published over 75 peer reviewed papers on geomagnetism, seismology, gravity, tectonics, geomorphology, and natural hazards. Dr. LaBrecque is focused upon the GNSS enhancement of Tsunami Early Warning Systems (GTEWS) for the Indo-Pacific region.
