Christian Nansen. Professor Christian Nansen, an agricultural entomologist, specializes in insect ecology, integrated pest management, remote sensing, host plant stress detection, host selection by arthropods, pesticide performance, and use of reflectance-based imaging in a wide range of research applications. He joined the UC Davis Department of Entomology and Nematology in 2015, after holding faculty positions at Texas A&M, Texas Tech, and most recently at the University of Western Australia. "We are seeking to develop food production practices that reduce reliance on pesticides in ways that are both environmentally sound and economically feasible," he writes on his website. "Often, insect pest outbreaks occur in crops that have already been weakened by environmental stressors such as insufficient water or fertilizer. This suggests that optimal management of crop inputs can be used to minimize the risk of pest outbreaks. We are investigating innovative crop management as a form of “preventive medicine” that reduces current reliance on pesticide applications." (See more)

The ranking of scientists is at https://elsevier.digitalcommonsdata.com/datasets/btchxktzyw. It is a publicly available database "of top-cited scientists that provides standardized information on citations, h-index, co-authorship adjusted hm-index, citations to papers in different authorship positions and a composite indicator (c-score). Separate data are shown for career-long and, separately, for single recent year impact. Metrics with and without self-citations and ratio of citations to citing papers are given. Scientists are classified into 22 scientific fields and 174 sub-fields according to the standard Science-Metrix classification. Field- and subfield-specific percentiles are also provided for all scientists with at least 5 papers. Career-long data are updated to end-of-2022 and single recent year data pertain to citations received during calendar year 2022. The selection is based on the top 100,000 scientists by c-score (with and without self-citations) or a percentile rank of 2% or above in the sub-field. This version (6) is based on the October 1, 2023 snapshot from Scopus, updated to end of citation year 2022. This work uses Scopus data provided by Elsevier through ICSR Lab (https://www.elsevier.com/icsr/icsrlab). Calculations were performed using all Scopus author profiles as of October 1, 2023. If an author is not on the list it is simply because the composite indicator value was not high enough to appear on the list. It does not mean that the author does not do good work."
