Researcher, Conservator, and Lecturer
With over 30 years of experience in conservation and materials research, I am grateful to have a network and international recognition that allow me to continue expanding the boundaries of knowledge and awareness in conservation techniques
Mission
Senior art conservator, teacher and researcher since the early years of career, with a mission to share knowledge with younger generations, with colleagues, and in cultural outreach contexts.
Vision
Problems and research questions are resources for a creative approach.
Scientific research and conservation practice
Art conservator who accepted complex challenges, with a special interest for the structural problems. Researcher and teacher in conservation science with a mission to share knowledge with peers, with younger generations, and in cultural outreach contexts.
Waiting to defend the Ph.D. dissertation in the spring of 2025, ” Mechanical and morphological characterization of canvas paintings supports. The correlation with tension on stretcher” at the Delft University of Technology, Aerospace Structures and Materials. The Ph.D. thesis is a continuation of the previous research, and started with the construction of computer-controlled devices for material testing of historical paintings and mock-ups, which allow to perform biaxial and uniaxial tensile tests, peel tests and flexural tests according to international standards.
Research resulted in the quantitative characterization of the morphology and the mechanical response of a set of historical samples, with recurring characteristics correlated to warp and weft directions of the textile.
Fellow of the International Institute of Conservation, member of ICOM-CC, CEO and CTO of Equilibrarte, he has a strong interest in the relationship existing between conservation and science. He has published over 80 scientific papers and a book, and promotes education through conferences and residential workshops.

Perspective
Research produces professionals who explore materials and the outcomes of their decisions with awareness, knowledge, and curiosity. It has driven my career as a conservator, teacher, and conservation scientist.
Interests and vision
My interests are mainly in the mechanical aspects of conservation, the field I have investigated the most, but I am also very interested in all aspects of the negotiation between the needs of historical artifacts and those of the different stakeholders, especially when it comes to treatment, including aesthetics and reintegration of losses.
Early research
I developed a method to conserve the original stretchers while applying measurable elastic tension to the painting. Shortly thereafter, I promoted and directed a three-year research project described in a book that is, to date, the only existing publication devoted entirely to the analysis of the effects of tension on canvas paintings.
Ph.D. research
Focusing on the morphological characterization of historical canvas painting supports, my doctoral research produced a wealth of unprecedented data. Using custom designed and built testing equipment, historical textiles were also mechanically characterized and correlations between warp and weft directions were established.
Research on cold lining methods
The treatment of Titian’s painting “David and Goliath” was the starting point for research into lining methods in 2011, based on a modified ” mist lining”. The adhesive performance obtained with the different combinations of variables is measured with peel tests in order to obtain a certain degree of predictability. A purpose-made portable testing machine has been designed and built for this purpose. The research has been the subject of intensive workshops since 2013.
