Research interests

Evolutionary ecology, social adaptation, Darwinian agriculture

 

 

My research examines the universal social tension between self-interest and group productivity. In one aspect of my work, I develop models to predict how natural selection will resolve this tension and favour competition or cooperation among individuals. Social evolution theory has revolutionized our understanding of animal behaviour and, more recently, the basic and applied biology of microbes. Yet although plants clearly live and interact in groups, social evolutionary thinking has not been fully exploited in plant science and agriculture. My research aims to (i) predict competitive and cooperative traits of plants; (ii) discover the traits and genes underlying efficient cooperation among plants in agriculture; and (iii) discover examples where cooperation among plants has evolved in nature. To address these problems, I currently use the genetic and genomic tools available for Arabidopsis and wheat.
