Agricultural and Resource Economics

Research Interests

With the vast and growing body of empirical evidence of the returns to agricultural innovation and the scope for advances in genomics and digital mechanisation, I have become convinced that greater investments in the development of agricultural innovation systems is an important pathway for economic growth, and perhaps the only pathway for achieving environmentally sustainable global economic growth. For the past decade I have focused on the economics of research and funding, intellectual property management as well as agricultural innovation systems and infrastructure.
