Allan Sim
I am an Honorary Associate of the Institute. As a staff member I supported scientists providing technical input to a variety of research projects. I also managed the Plant Growth facilities at the Craigiebuckler site for the past 20 years and have extensive knowledge of the capabilities, set up and the maintenance of the equipment.
Current research interests
Presently my work is mainly concerned with Carbon Sequestration in soils.
