Research interests centre on the processes involved in crop domestication, ranging from major crops through orphan crops to new crops, and applying new lessons from one category of crops to another along the domestication continuum. My interests begin with the genetics of crop domestication and resource management, but extend to the other processes involved in crop development and promotion. They also extend to understanding crops within a range of different production and food system contexts. These research interests are reflected in publications that review the genetics of orphan crop mainstreaming and that assess the use of biodiversity to sustainably intensify global food production. I am also interested in informing research strategy and policy development for agriculture. I have been engaged in work in 20 tropical or sub-tropical countries.
