James QuiltyAs head of Zeigler Experiment Station, James leads a team of staff dedicated to provide conditions required for contemporary rice research. He liaises with most levels of research and administration within IRRI to deliver the ZES services quickly and efficiently for its customers.

James oversees field operations (machinery), field maintenance (agronomy), irrigation, bioenvironment and administrative groups. This includes the day-to-day operations, but also a number of projects to improve both the infrastructure and the processes at the Zeigler Experiment Station to match 21st century requirements.

Prior to being ZES head, James worked with the Crop and Environmental Sciences Division (CESD) on the ecological intensification (EI) platform. The EI platform provides a field laboratory for developing and researching probable futuristic rice production systems. It involves the adaptation of mechanized agronomic activities to rice production, in conjunction with the implementation of efficient irrigation technologies, and the intensification and diversification of crop scheduling. James’ role in this project is determining the ecological footprint of conventional and alternative futuristic rice-based agricultural systems.
