Interessi di ricerca

La mia attività di ricerca è prevalentemente focalizzata sullo studio delle possibili correlazioni tra le caratteristiche cristallochimiche sia di bulk che di superficie di fibre minerali (amianto e altre fibre minerali non normate come fluoro-edenite, winchite, erionite, ed antigorite) e la loro reattività chimica e tossicità. Mi occupo, inoltre, della valutazione della pericolosità legata alla presenza dei NOA (Naturally Occurring Asbestos), ovvero minerali fibrosi nel loro contesto naturale. Tale linea di ricerca adotta un approccio multi-analitico (XRPD, HRTEM, FESEM, varie tecniche spettroscopiche come l’XPS e l’ICP, anche utilizzando facilities di luce sincrotronica), è estremamente interdisciplinare e viene pertanto svolta collaborando attivamente con colleghi fisici, chimici, biochimici e patologi.

Attualmente sono principal investigator di un progetto biennale dal titolo “Caratterizzazione cristallochimica e studio della reattività di superficie di fibre minerali di interesse ambientale e sanitario ai fini di un'accurata analisi del rischio di contaminazione”, recentemente finanziato nell’ambito dei progetti BRIC INAIL 2019 (attività di ricerca 2019-2021).
