Research

My research concerns classical coordination and organometallic chemistry in solution and is aimed to the development of functional coordination/organometallic compounds, i.e. compounds that, by virtue of their reactivity and/or chemical-physical properties, can be exploited in other, more complex, environments.

In particular, I have two main research lines:

Development of metal complexes for photocatalysis and supramolecular assemblies (Research area: Energy, Environment and Sustainable Chemistry)
Development of metal complexes for imaging and therapy (Research area: Drug Design, Synthesis and Formulation)

For more details on my research lines, please click on the links that you find above.

The synthesis and characterization of the metal compounds is performed by my group, that is typically composed by one Ph D student and a variable number of master students in chemistry. Occasionally, postdoctoral fellows and visiting Ph D students from abroad join the group.

The research benefits of a tight network of collaborations within the Department (in particular with Dr. Gabriele Balducci, Prof. Elisabetta Iengo and Prof. Barbara Milani). In addition, both main research lines have fruitful collaborations with other Departments (Prof. Gianni Sava, DSV) and local Institutions (Dr. Alberta Bergamo, Callerio Foundation; Dr. Nicola Demitri, ELETTRA Sinchrotron Trieste), as well as with Italian (Prof. Luigi Messori, University of Florence) and foreign Universities (Prof. Roger Alberto and Dr. Gilles Gasser, University of Zurich).
