Wenlu received her Ph.D. degree in Geographical Sciences at the University of Maryland in 2018. She received the BS degree in Mechatronics Engineering from Beijing Institute of Technology in 2008 and the MS degree in Electrical Engineering from Chinese Academy of Sciences in 2011. Wenlu's interests mainly focus on the application of lidar and radar remote sensing on forest structure and biomass estimation. She has been a NASA Earth and Space Science fellow (NESSF) from 2014-2017 and is currently working on fusion between lidar data from NASA's Global Ecosystem Dynamics Investigation (GEDI) mission and Interferometric Synthetic Aperture Radar (InSAR) data from DLR's TerraSAR-X/TanDEM-X mission for improved forest biomass estimation over large areas.
