Research Scientist

Catia’s main research activities are related to the development of mathematical models of forest structure and growth. She is currently working on the development of an individual-tree growth model for forecasting tree growth in irregular and mixed species forest stands, such as those resulting from the application of continuous cover silviculture.

She is the main developer of the stand level M1 growth and yield model, which underpins the current GB Forecast System and FR’s forest carbon accounting models. She also contributes to the development of empirical relationships describing fundamental tree properties. While her main current responsibilities are within the growth and yield modelling research area, she is also interested in supporting the development of process-based models and in the past she has led a modelling study of rainfall interception in conifer and broadleaf canopies.

Catia has also made a major contribution to the formulation of a Strategy for the Forestry Commission and Forest Research on development of models of Growth, Yield and Carbon balance, including supporting data acquisition.

Catia joined Forest Research in 2001 and is one of the main developers of improved mathematical models of forest growth and yields.

Catia’s research background is in theoretical and computational solid state physics. She obtained an MSc in Physics from the University of Modena (Italy) in 1990 and a PhD in Physics from the University of Ferrara (Italy) in 1994. From 1994 to 2001 she conducted research at the Department of Chemistry, University of Konstanz, Konstanz (Germany) (1994-1995), at the Max-Planck Institut für Festkörperforschung, Stuttgart (Germany) (1995-1999) and at the Department of Physics, University of Modena and Reggio Emilia, Modena (Italy) (1999-2001). During these years her research activity was mainly devoted to the development of ab-initio computational methods for electronic structure calculations and the investigation of the electronic properties of low-dimensional systems.
