Dr David Read
Research Fellow
About
I am currently appointed as a postdoctoral fellow with FABI and am part of the Grain Research Programme. My broad research interests include plant pathogenic viruses, their arthropod vectors and control of their spread. I completed both my masters and doctoral studies with FABI and went on to complete a number of postdoctoral studies primarily in the agricultural research environment.
Both my MSc and PhD studies focussed on the characterisation of Citrus tristeza virus populations within Southern Africa and how population structures of this virus impacts its control using mild-strain cross protection. My postdoctoral studies involved using a non-targeting RNAseq approach to characterise viral populations of maize, potato and sweet potato in both South Africa and east Africa. In addition to this, a number of opportunities arose to characterise novel viral pathogens in a number of other agriculturally important crops, as well as ornamental and indigenous plant species, which include Macadamia,Alcea, Alstroemeria andwheat.
My research fellowship will continue to focus on the virology of agricultural and ornamental host species and to grow capacity in the plant virology space within FABI.
