Saskia A. Hogenhout FRS (born 1969), is a Dutch professor of entomology and ecology specialising in molecular plant, microbe and insect interactions.

[3][1][4][5] Hogenhout was educated at Vrije Universiteit Amsterdam with an MSc in Biology in 1994, her PhD looked at the molecular basis of luteovirus-aphid interactions and was awarded at Wageningen University in 1999.

[2] After her PhD, Hogenhout moved to Ohio State University to be assistant and then associate professor[6] and since 2007 has been Group Leader in plant health at the John Innes Centre in Norwich.

[10] Hogenhout found that the aphid can adapt the virulence proteins it produces in response to the plant species it is feeding on; and as it can reproduce asexually, producing a clone of genetically identical offspring, local populations of aphids can adapt quickly to their environment.

[12][13] Hogenhout is leading a major UK consortium project BRIGIT carrying out research into transmission of the bacterial pathogen Xylella fastidiosa, which has caused widespread plant disease in Southern Europe.
