Research are focused at the exploitation of mineral resources Italian with particular regard to industrial minerals and rocks. In this area there are multiple research lines.
Study of pyroclastic deposits (especially Italian but also foreign) that underwent  secondary mineralization processes that led to the formation of minerals of high industrial interest. In this area have been reconstructed the genetic mechanisms of zeolites in some of the most important Italian formations and particularly the Neapolitan Yellow Tuff, the Ignimbrite Campana, the Tufo Giallo della Via Tiberina and volcanoclastites of northern Sardinia; regarding foreign deposits, pyroclastics of the Canary Islands, Eifel (Germany) and Mexico were studied. These studies have demonstrated that the zeolite minerals deposits related to peculiar depositional mechanism such as pyroclastic flow, or more generally, from interaction with waters can not be traced back to one of the six genetic models proposed by Mumpton (1979) and for a correct interpretation of the process, the acquisition of detailed geological and mainly volcanological information are required. Alongside researches were conducted on crystal chemistry features of some mentioned above deposits in order to deepen mineralogical structural information on those zeolites

Use of zeolitites in areas of technological interest.
In particular, it was demonstrated the possibility of using the tuffs of Campania, containing phillipsite and chabazite, for soils remediation/amendation. Particular attention was paid to the possibility of use of such materials in the ceramic sector, with a melting role , in partial replacement of traditional and more expensive feldspars, both as a raw material for the preparation of expanded lightweight aggregate (LWA). This methodology was finally extended to the recovery of waste in the natural stone for the production of LWA for the packaging of structural lightweight concretes.

Use of zeolitites in the pharmaceutical sector.
The collaboration undertaken with the Department of Pharmaceutical Chemistry, University of Pavia in the past and more recently with the departments of Chemical Engineering, Materials and Production and Industrial Pharmacy of Federico II , financed by a PRIN, allowed to demonstrate that rocks with a high content of zeolite may be used as a cation-releasing-carrier for antibiotics in topical applications. In fact, it is possible to use zeolitites, with prevalent clinoptilolite, then a low-cost material, such as inorganic carrier capable of transmitting ions Zn2 +. This showed benefit, from the action of zinc adjuvant, when applied together with an antibiotic (erythromycin) in anti-acne therapy.
Use of zeolitites in the environmental sector
Recent research are directed primarily to the treatment of wastewater from nuclear power plants and the subsequent neutralization of contaminated materials and the evaluation of the risk induced in animal feed made from mineral products

The Applied Mineralogy for Cultural Heritage
The working group has participated in the establishment of the Regional Competence Centre for Development and Transfer of Innovation Applied to Cultural Heritage and Environment INNOVA in which he made the cross-thematic Laboratory and Diagnostic Techniques Aimed at Restoration and the Preservation of Assets cultural with the participation of researchers of the Faculty of Architecture, Engineering and Sciences.
Searches are mainly directed to the study of the rocks of the Campania used as ornamental stones, and to provide a contribution of knowledge and ideas on these materials so widely used in historical architecture of Campania is to check whether the conditions for a recovery of sites ancient extraction and a consequent enhancement of these materials. This activity is carried out in close collaboration with experts in architectural history and restoration, as the main purpose of the research is to improve the knowledge on the stone when placed in work, interpreting degradation processes that involve and then collect all the useful information for the preparation of a project that gives long-lasting results. An important role in this phase is done by the diagnostic and in particular by the built-in diagnostics that allows, through the contribution of multidisciplinary experiences, to know and interpret the historical architecture and guide the intervention. This is to: improve the cognitive phase, improving the operational phases of intervention and reduce the cost of implementation of specialized investigation optimizing and integrating the diagnostic tests that, through a shared project, will be reduced to those strictly necessary.
