My research focuses on forest operations, with special reference to advanced mechanization and biomass harvesting operations. I have worked with biomass operations since 1985, at the time of my graduation, and I have joined the first CNR field tests in 1989. Since then, I have steadily worked on the subject, covering a wide range of forest , operation and wood biomass feedstock types with the largest possible array of different collection and processing techniques, from manual to fully mechanized or autonomous. In that work, I have teamed up with many experienced colleagues,which is also witnessed by the Author list in my publications. I have worked on the subject of forest operations in many countries, including most of Europe, Australia and New Zealand, Argentina and Brasil, South Africa and the USA, where my association with the University of California dates back to 1998. While working on operational efficiency and cost, I have not disregarded some fundamental conditional fields, including the environmental impact and the entrepreneurial. I also cooperate within the FAO and the International Energy Agency (IEA), I have extensive and continued experience in the harvesting of plantations forests, gained in: Europe and North America for poplar; Australia, Europe, North America, South America and South Africa for Eucalypt; South America and New Zealand for Pinus radiata; and Asia for acacia
