Dr. Jon Ranson is an earth scientist specializing in radar and lidar remote sensing of forests. He uses these tools for studying vegetation type and biomass in ecosystem research at NASA’s Goddard Space Flight Center in Greenbelt, Maryland. He also serves as the Chief of Goddard’s Biospheric Science Laboratory, which is advancing the use of satellite technology to study the carbon cycle and terrestrial ecosystems. Dr. Ranson has participated in numerous field campaigns in the United States, Canada and Siberia to improve our ability to measure and monitor vegetated ecosystems from space. He enjoys hiking, birding, music and outdoor cooking.
Dr. Vyacheslav Kharuk, a forest ecologist, is Head of Forest Ecology and Monitoring Branch, Sukachev Forest Institute Siberian Branch of the Russian Academy of Science, in Krasnoyarsk, Siberia and Head of GIS Chair at Siberian Federal University. He has collaborated on several NASA- supported projects including projects in Maine, Canada and Siberia with Dr. Ranson and other NASA and USDA Forest Service scientists over the past several years. Dr. Kharuk leads the field and remote-sensing data activities at the Sukachev Institute and collaborates in data analysis research at NASA GSFC.
Dr. Guoqing Sun is a Research Professor at the University of Maryland-College Park, and is also affiliated with NASA’s Goddard Space Flight Center Biospheric Sciences Branch. He has been involved in research on remote sensing and GIS applications since the early 1980s , and has worked as a principal researcher and investigator in various NASA programs. His speciality is in radar backscatter and lidar waveform models and applications of multi-sensor (lidar, radar and passive optical sensors) data in forest ecosystem studies.
Dr. Sergei Im is a scientist at the V. N. Sukachev Institute of Forests, Siberian Branch of the Russian Academy of Science in Krasnoyarsk, Siberia. He completed his undergraduate Studies at Krasnoyarsk University in 2001 and completed his post-graduate studies at the V. N. Sukachev Institute. He is author and co-author of many scientific papers that have been published in Russian and International journals. His special interests are informatics such as GIS. Dr. Im is a skilled computer programmer. He has a particular interest in microwave and optical remote sensing for analysis of land cover dynamics.
Dr. Ross Nelson is a physical scientist who works for the Biospheric Branch of the NASA Goddard Space Flight Center in Greenbelt, Maryland. He completed his B.S. in Forestry at the University of Maine, Orono, his Master’s in Forestry/Remote Sensing at Purdue University and earned his Ph.D. in Forestry/Biometrics at Virginia Polytechnic Institute and State University. He participates in several areas of research. One important area is the use of airborne laser data to characterize the forest canopy and estimate forest biomass, volume and carbon. He is also working to use moderate and high-resolution satellite data to monitor tropical and subtropical forest conversion. Ross is also developing statistical and image processing procedures for continental and sub-continental resource assessment using satellite imagery.
Pavel Oskorbin is a scientist at the V.N. Sukachev Institute of Forests, Siberian Branch of the Russian Academy of Science in Krasnoyarsk, Siberia.
