Dr Alessandra Catena 

was born in Rome in 1973, she is married and has two daughters. 


1997 she attended the course "Landscaping Architecture," held by Prof Sofia Varoli Piazza at the University della Tuscia, Viterbo, Italy; 
1998 she participated in the Workshop "Plant pathology in an urban environment," held in Livorno, Italy; 
1999 - 2001 she joined the Remote Sensing Unit of the Italian Institute of Health, Rome, to learn and study the use of Thermography associated to tree stability assessment; 
1999 - 2000 she took part in the drafting of a soil bioengineering manual, as supervisor of various sites, under the aegis of the Region Lazio, and in cooperation with the Italian Soil Bioengineering Association (AIPIN) and the University della Tuscia, Viterbo, Italy; 
1999 she spent a three-month training period with Ferrara-based firm Progetto Verde. She supervised various sites intended to assess tree stability in Ferrara and its province, in Cava de´ Tirreni (Salerno) and various other places in the Region Marche, thus studying the VTA and various tools in depth, such as Resistograph, the impulse hammer, Thermography and Fractometer; 
1999 she attended the workshop "Learning with a view to managing: census of parks and gardens. Methods and Aims," Ferrara; 
1999 she attended the course "Introduction to ArcView GIS," held by ESRI Italia at the Italian Institute of Health (Rome); 
2000 she attended Prof Raimbault´s course "The tree as a biological entity," Ferrara;
2000 Degree in Forestry at the University della Tuscia, Viterbo; 
2001 she followed the course "Stability assessment and tree management in an urban environment," organized by the Agronomist and Forester Association of Rome; 
2001 she participated in the workshop "The culture of private and public parks and gardens. Possible synergies," organized by the City of Bologna; 
2001 - 2002 she attended the course "Safety Coordinator in temporary and mobile work sites (Legislative decree 494/96)," at the Provincial Training Centre, Ferrara, and obtained the relevant qualification; 
2002 she attended Prof Klaus Mattheck´s technical workshop "Recent acquisitions on Visual Tree Assessment," organized by the International Society of Arboriculture, Italian Chapter, in Milan, Italy; 
2002 she took part in an International workshop organized in Villa Durazzo, Santa Margherita Ligure, by the City of Sanremo and the Sanremo Palm Tree Study Centre, and gave demonstrations on thermography; 
2002 she qualified as Forester and enrolled in the Agronomist and Forester Association of Rome; 
2004 she attended M. Schlag´s technical workshop "Integrated Tree Control: Dynamic Aspects of Wood-decomposition in Living Trees," Maastricht, NL; 
2004 she attended Prof K. Mattheck´s technical workshop "Tree Mechanics as an Innovator in Arboricultural Practice," Maastricht, NL; 
2009 she attended Prof. Mattheck´s 5th Technical Workshop "Assessing Tree Stability with the VTA," organised by the SIA, Demetra and the City of Rome, Semenzaio di San Sisto, Rome.


2000 - 2005 she became immediately active in tree assessment as a freelance tree Consultant and worked with some of the most important Italian firms (including AR.ES. and Progetto Verde, Ferrara; Seacoop, Turin; Agri2000, Bologna; Demetra, Besana Brianza; Green Operator, Milan) using both the VTA and Thermography for Public Bodies and Administrations and the private sector. She worked on many tree stability projects in a number of Italian cities and the Netherlands; 
Over the years, she gave demonstrations of thermography to Public Administrations in Italy and abroad and to non-Italian researchers, including prof. Voichita Bucur of the Institut National de la Recherche Agronomique (INRA) - Centre de Recherches Forestières de Nancy, France, in September 2001, who included this technique in her book "Nondestructive Characterization and Imaging of Wood" (Springer, 2003). 
She took part in VTA-Resistograph-Thermography-Picus cross examinations organized by sector firms and Public Bodies; 
2004 she set up Catena & Thermography with Dr. Giorgio Catena, whose mission was the introduction of Thermography in tree assessment. After closing the company, she started to work in the Public Administration (Veio Regional Park); 
2005 (December) - to date she works full time at the Veio Regional Park, but continues to be involved in Treethermography®, actively participating in the technique´s development. 


1999 - 2000 she conducted many thermographic investigations on trees attacked by fungi of various species, in cooperation with the Remote Sensing Unit of the Italian Institute of Health, Rome: some of these results were published and presented at Conferences; 
1999 she conducted thermographic investigations on 10 lime-trees attacked by Ganoderma and located along Viale dei Tigli, that leads from Torre del Lago Puccini to Viareggio (Lucca), in cooperation with Prof Alberto Panconesi of Florence-based CNR (Italian National Research Centre); 
2001 she conducted a comparative Thermography-Resistograph examination on a veteran lime-tree located along Viale Gramsci, Colle di Val d´Elsa (Siena); 
2001 she participated in a comparative Thermography-Resistograph-Fractometer test at Muzio dé Tommasini Park, Trieste, in cooperation with firms Agri2000, Bologna and L´idea verde, Trieste, that felled the trees that were deemed dangerous; 
2002 with the use of a modern thermal camera, she carried out a measurement of a row of lime-trees, that had already been assessed in 1987 by Dr G. Catena, in order to check their condition; 
2003 she was entrusted by Rome´s Garden Service with the assessment of the stability of various trees in Villa Borghese and 70 plane-trees located along Via Galvani (Rome) with the thermal camera; 
2005 - 2006 she conducted monthly measures on a veteran holm-oak to assess the influence of environmental conditions on thermal images.
