My current research has mainly been on the smallholder agriculture development, cooperatives and collective enterprises in agriculture industry, and agricultural value chains. I regularly speak to farmers and other stakeholders in agricultural value chains on my research. Lists of my publications and students supervised by me are provided below.

Smallholder agriculture development

This has been a recent major research area my career. I have a passion for querying alternative ways of improving the livelihood of smallholder farmers and their income in the context of agri-food industry transformation in Sri Lanka and in other developing countries predominate with smallholder agriculture.

Cooperatives and collective enterprises in agriculture industry

Among various business models cooperatives, farmer organizations and various other producer groups found to have many advantages to their owners. Exploring issues faced by the cooperatives and producer organizations owned and control by the farmers and other actors in the agriculture industry is another area of research in my carrier. In particular, I am interested in researching their role of linking farmers to modern markets, governance and management challenges embed in them and organizational innovations.  

Agricultural value chains

Agricultural value chains came into prominence following the growth of demand for quality and safe foods. I am interested in analyzing the distribution of value created along the chain and opportunities and constraints in developing agricultural value chains in developing countries.
