Dr Joris Alkemade

Subject: Biology, Plant Sciences and Zoology

College appointment: Calleva Research Associate


I am a Postdoctoral Research Associate at the department of Biology and the Calleva Research Centre at Magdalen College. I did my bachelor and master in plant sciences with a focus on plant pathology at Wageningen University in the Netherlands. During my studies I was mainly involved in projects related to Panama disease in banana caused by Fusarium oxysporum. After graduation I went to Switzerland to do a PhD on anthracnose disease caused by Colletotrichum lupini in white lupin at the research institute for organic agriculture (FiBL). White lupin has the potential to increase plant-based protein production in Europe and reduce soy imports. During my postdoc I will further explore the genetics of C. lupini but the main topic is to understand the effect of fungicide applications on fungal crop pathogen evolution. Eventually we aim to use the acquired insights to develop novel control strategies.
