I started research work on forest engineering in the last year of my BSc at Tehran University where I was involved in forest road network planning, road drainage construction and planning for reforestation areas. For my masters thesis I studied the productivity of mule logging in native forests and the amount of damage mule logging causes to sites. For two years I worked as a research assistant at the university, carrying out several studies on the productivity of cable skidders, tractors, chainsaw operators, loaders and trucks in the mountainous forests of Iran. My research also explored ways to minimise soil compaction and stand damage when using ground-based harvesting systems.

I completed my PhD at BOKU University of Vienna (Austria). During my graduate study I developed productivity models for Austrian tower yarders working in steep terrain. Another part of my thesis looked at optimal road spacing for cable cranes using network analysis. While it was interesting to see how harvesting systems affect the forest road networks, I investigated the productivity and cost of two forwarding systems in Southern Austria in order to compute the optimal road density for this typical ground-based system in Central Europe. I worked in Vienna as a postdoc, exploring forest biomass projects and the long-term cost analysis of harvesting machinery.

I believe there are many research opportunities in Australia which will help me investigate different harvesting operations. My research interests are improving the efficiency of different harvesting systems, minimising the environmental impacts of timber harvesting, studying biomass harvesting as a renewable energy resource and developing decision support systems for harvesting planning.
