Biography

Jeffrey Walker is a Professor and Head of the Department of Civil Engineering at Monash University. He is undertaking research on soil moisture remote sensing and data assimilation, including development of the only Australian airborne capability for simulating new satellite missions for soil moisture. He is contributing to soil moisture satellite missions at both NASA and ESA, as a Science Definition Team member for the Soil Moisture Active Passive (SMAP) mission and Cal/val Team member for the Soil Moisture and Ocean Salinity (SMOS) mission respectively.



Professor Jeffrey Walker received his BEng(Civil) and BSurv degrees in 1996 with Hons 1 and University Medal from the University of Newcastle, Australia, and received his PhD in Water Resources Engineering from the same University in 2000. His PhD thesis was among the early pioneering research on estimation of root-zone soil moisture from remotely sensed surface soil moisture observations. He then joined NASA Goddard Space Flight Centre to implement his soil moisture work globally. In 2001 he moved to the Department of Civil and Environmental Engineering at the University of Melbourne as Lecturer, where he continued his soil moisture work, including development of the only Australian airborne capability for simulating new satellite missions for soil moisture. In 2010 he was appointed as Professor in the Department of Civil Engineering at Monash University where he is continuing this research. He is contributing to soil moisture satellite missions at both NASA and ESA, as a Science Definition Team member for the Soil Moisture Active Passive (SMAP) mission and Cal/val Team member for the Soil Moisture and Ocean Salinity (SMOS) mission respectively.
