Steve Jupe is the Biology Coordinator for the Reactome project in the Molecular Systems team at the European Bioinformatics Institute. His role is primarily the identification and addition of new topics to Reactome, particularly in the areas of immune signalling and haemostasis. Steve has a BSc in Biology. For his PhD he researched the growth-regulating activity of the plant hormones gibberellin and ethylene at UCW Aberystwyth, obtaining his PhD in 1989. This was followed by postdoctoral research positions at the Institute for Arable Crops Research, Rothamsted and later at Long Ashton, where he became a molecular biologist as part of the AFRC plant molecular biology initiative. He worked on plant-pathogen interactions at Royal Holloway, University of London before moving away from the lab in 1996 to join the Bioinformatics group at SmithKline Beecham, later merging with Glaxo to form GlaxoSmithKline, where he worked on numerous drug discovery projects and maintained a database of GPCRs. Steve joined the Reactome group in 2009 as a Curator, extending Reactome's coverage predominantly in the areas of Immune signaling and Hemostasis.
