After her PhD, Saunders worked as a postdoctoral researcher at the Sainsbury Laboratory.[5][6][7]
In 2014, Saunders launched her own research group at the John Innes Centre.[8] She investigates pathogens that significantly threaten agricultural production and food security.[9] Saunders has focused on Puccinia, which cause wheat rust. In particular, she has studied Puccinia striiformis f. sp. tritici.[10] She uses genomics-based approaches to monitor the dispersal of pathogens at an international scale.[11] She developed "field pathogenomics", a surveillance technique that can analyse diversity in pathogen populations from field samples.[11]
In 2018, Saunders published the identification of wheat stem rust in the UK for the first time in sixty years. This devastating disease has been associated with crop failure throughout history, although in the UK the last epidemic occurred in 1955. Saunders' observation triggered an international investigation, and identified that the UK strain belonged to the Digalu race.[12][13]
Saunders has worked with the International Maize and Wheat Improvement Center (CIMMYT) and the Ethiopian Institute of Agricultural Research to create a platform that enables the diagnosis of plant diseases in realtime.[11] The platform, Mobile And Real-time PLant disEase (MARPLE),[14][15] seeks to monitor the spread of wheat yellow rust in Ethiopia and provide insight that can guide disease management responses.[16] She subsequently launched the programme in Nepal and Kenya.[17][18] When wheat strains diversify they can infect more rust-resistant varieties. As such, there is an urgent need to identify and monitor specific strains in real time.[17] As part of delivering this programme, Saunders offers training courses for plant pathologists.[17]

Awards and honours
In 2019, Saunders launched "Women in Wheat", a training programme to support women scientists working in wheat research.[22] In 2022, she was awarded the Rosalind Franklin Award and Lecture for her "innovative mentoring and training project to support and empower undergraduates and early-career female researchers in plant sciences at postgraduate and postdoctoral levels".[23][8]
