Mandana specialises in soil salinity and sodicity: reclamation and revegetation of salt affected land, prediction of water and solute movement in soil

Mandana is a soil scientist, whose research focuses largely on soil salinity, water and solute movement in soil and hydro-geochemical modelling. During her PhD, Mandana predicted the success of reclamation for salt affected soil using numerical models. Since the completion of her PhD, Mandana has been involved in various research projects on saline tailings and soil affected by mining activities. Mandana’s current research focuses on red mud (bauxite residue), where salinity can play a critical role in deposition for red mud in storage facilities.

Mandana has both BSc and MSc degrees in Agricultural Engineering from The University of Tehran. She also has Master of Environmental Management from The University of Queensland. Mandana completed her PhD in soil sciences at The University of Queensland. Before joining SMI as a postdoctoral research fellow, Mandana worked with NSW Department of Primary Industries on amelioration of subsoil constraints. Mandana is a reviewer of high ranking journals, and she is member of Soil Science Society of America.
