Luca Belelli Marchesini obtained a Degree in Forest Sciences and a PhD in Forest Ecology at the University of Tuscia in 2002 and 2007, respectively.

His scientific interest has been directed to the biogeochemical cycles of terrestrial ecosystems since the early years of research activity, with particular attention to the quantification of carbon and energy balances and to the understanding of their variability in response to climatic factors, as well as natural and anthropic disturbances, such as fires and land use changes.

Since 1999, he has participated in international EU funded projects carrying out experimental research in Italy, Russia, Spain, Ghana and the Netherlands based on measurements of greenhouse gas fluxes (carbon dioxide and methane), mainly by micrometeorological techniques, in forest, grassland and wetland environments.
He was a postdoc researcher at the Department of Forest Environment and Resources, University of Tuscia, (2007-2011); during these years his professional experiences, in addition to research, included consultancy on the application and development of methodologies for carbon sequestration forest projects (in Ukraine, Montenegro and Argentina) in the framework of the flexibility mechanisms of the UNFCCC.
At the Vrije Universiteit (VU) of Amsterdam (Netherlands) (2011-2015) he carried out research on the impacts of global warming on the stability of the permafrost carbon stocks of the Siberian Arctic tundra.
Between 2016 and 2018 he was Chief Researcher at the Far Eastern Federal University of Vladivostok (Russia), overseeing the launch of a line of research on the monitoring of greenhouse gas fluxes in the Russian sector of Asia-Pacific region, and then Researcher at the Agricultural Technological Institute of the RUDN University of Moscow (Russia).

In recent years, a new growing interest in the application of Internet of Things technology in the field of forest ecology, has led him to contribute to the development of a patented device for measuring the biological processes of woody plants and forest microclimate.

Since 2019, he has been a researcher at the Edmund Mach Foundation's Research and Innovation Center in the field of forest ecophysiology, dealing with forest monitoring using IoT devices and infrastructures for the measurements of greenhouse gas exchanges with the atmosphere.

Luca Belelli Marchesini is author of 40+ papers in international peer-reviewed journals and 5 book chapters (Index H= 23, 1867 Scopus citations), member of the editorial board of the journal Forests and reviewer for the main scientific journals in his professional field.
