Contributions, Impact and Stature:
Dr. Kustas has over 390 scientific publications of which 265 appear in peer reviewed journals and 21 are book chapters. He is recognized world-wide as the leading expert in remote sensing applications for modeling land surface fluxes and soil-vegetation-atmosphere interactions. His international standing and scientific stature in remote sensing research was cited in Scientometrics (96:203-209, 2013) where a bibliometric analysis ranked him 5th most productive out of the top 20 remote sensing authors world-wide and in the top 10 in research impacts using three different citation metrics. In addition, in 2020 he was included by Stanford University scientists in a publication of a comprehensive list that identified the top 2% of scientists worldwide. The ISI Web of Science citation report computes an h-index of 74, and Google scholar computes an h-index of 90 for Dr. Kustas, exceeding most of his peers in remote sensing and hydrology. He has mentored 30 postdoctoral and visiting scientists (4 ARS-funded postdoctoral positions) and 10 M.S. and 14 PhD students. He currently serves on 3 PhD committees and supervises and mentors 2 postdocs. He has been awarded research grants from NASA and USDA totaling nearly $5 million in support for his research, particularly leading large-scale multidisciplinary experiments selected through peer-review. A key component of these projects was the leadership of large multidisciplinary teams. As principal investigator (PI)/Co-PI, Dr. Kustas designed and coordinated large scale interdisciplinary remote sensing field experiments supported by NASA/USDA in Arizona (Monsoon 90), Oklahoma (Washita 92 Washita 94, SGP 97, SGP 99, CLASIC07), Iowa (SMACEX/SMEX02), Texas (BEAREX08), and California (GRAPEX). These have involved the coordination of field- and post-experiment research activities, including multiple aircraft, for dozens of scientists, postdocs and graduate students. The resulting research has made break-through contributions to basin and regional hydrologic and atmospheric modeling using remote sensing.
