Professor Brajesh Singh is an internationally recognised expert in the field of functional ecology and soil biology. Through his fundamental research, his work identifies the quantitative relationships between soil biodiversity and ecosystem functions and how natural/anthropogenic pressures such as global change affect this. His applied research harnesses the knowledge gained in fundamental research to achieve increased farm productivity, sustainable development, environmental protection and food security.

His research has advanced critical areas of ecosystem science, particularly linking soil biodiversity to key ecosystem functions and services and has developed tools to improve farm productivity and environmental sustainability. This includes climate adaptation tools for the agriculture industry, management solutions to increase soil organic matter, increased export market access for agriculture produces, and training for farmers, consultants and policy advisors in sustainable agriculture and the Sustainable Development Goals.
