Research Interests

I am primarily interested in the integrated behaviour of the soil-plant-microbe system and how the natural productivity, resilience and efficiency of the system can be optimised. I am also interested in how the behaviour of the system can be further enhanced by inputs so as to minimise the physical and environmental footprint of agricultural production. With a background in theoretical physics, my main contribution is in conceptual development and theory and I collaborate extensively with soil and plant biologists, and with physicists.

Management Responsibility

I am a member of the Institute Executive Committee and Scientific Director of the Delivering Sustainable Systems cross-institute research programme. This programme has around 80 fte staff with a budget of over £14M, and aims to develop methods for increasing production and quality while decreasing inputs.
