My primary research and teaching interests lie in the areas of stratigraphy and siliciclastic sedimentology. Particularly, during my Ph’D, I focused facies and basin analysis onto the Permo-Carboniferous to Early Triassic continental sequences. Biostratigraphy (lacustrine vertebrates, macro- and microfloras, tetrapod footprints) and palaeogeographic reconstructions are also among my field of interest.

The rich geologic environment and exposure of Sardinia and the Southern Alps, which I studied, offers a wide variety of potential research problems, and provide spectacular examples of stratigraphic features for students. Specific research projects include stratigraphic reconstructions of Upper Carboniferous to Early Permian sequences of NE Bulgaria, palaeomagnetism of Carboniferous-to-Middle Triassic deposits of Sardinia, basin analysis of Seui, Escalaplano-Mulargia and Cala Viola-Lu Caparoni Basins (Sardinia), W Collio and Orobic Basins (Southern Alps).



His primary research interests lie in the areas of stratigraphy and siliciclastic sedimentology, facies and basin analysis onto the Permo-Carboniferous to Early Triassic continental sequences (of Sardinia, the Southern Alps, Bulgaria, Southern France and Argentina). Biostratigraphy (lacustrine vertebrates, macro- and microfloras, tetrapod footprints) and palaeogeographic reconstructions are also among his fields of interest.

He actively participated in national and international research projects on topics still dealing with the Upper Palaeozoic of European and non-European regions:

- Cofin 1998: “Late Paleozoic Stratigraphic Evolution and tectonics in South Alpine and Apennine areas. Correlations with Sardinia and other areas of the western Mediterranean” (Coord. Naz. G. Cassinis);

-Bilateral Scientific Cooperation Programme 1998 between Consiglio Nazionale delle Ricerche (CNR) and Bulgarian Academy of Sciences (BAN) “Strashmir Dimitrov” (Stratigraphic Research on the Permian of Stara Planina area (Bulgaria) (Coord. G. Cassinis and S. Yanev);

- Cofin 2003: “Stratigraphy and palaeogeography in the late- and post-Hercynian basins of the Southern Alps, Tuscany and Sardinia, Italy. Comparisons with other areas of the Western Mediterranean and geodynamic hypotheses” (Coord. Naz. G. Cassinis).

- PRIN 2008 (coordinator local Unit): “Time constraints of sedimentary and magmatic events in late-to- postvariscan successions in the Southern Alps and Sardinia: geodynamic and paleogeographic inferences” (in G. Oggiano National coordinator Project).

-He is currently participating in the IGCP 575 (2010-2014): “Pennsylvanian terrestrial habitats and biotas of Southeastern Euramerica” (Coordinator C. Cleal, Cardiff).

He made field-work and geological maps on the Late Paleozoic to Early Mesozoic covers in different Sheets (National Geological Atlas scale 1:50.000: CARG Project) of Sardinia (Jerzu, Muravera) and of the central Southern Alps (Sondrio, Breno).

He is author or co-author of more than 50 peer-reviewed papers or contributions in volumes (30 international, among which 22 ISI), 9 geological maps, 7 guide-books (26 contributions), and presented about 90 communications and/or posters in National or international Congresses.



He collaborated in the organization of international meetings: Brescia 1999 (“The Continental Permian of the Southern Alps and Sardinia (Italy), Regional Reports and General Correlations”), Siena 2001 (“The stratigraphical and structural evolution of the Late Carboniferous to Triassic continental and marine successions in Tuscany, Italy. Regional reports and general correlation”) and Siena 2006 ("Stratigraphy and Palaeogeography of Late- and Post-Hercynian Basins in the Southern Alps, Tuscany and Sardinia (Italy). Comparisons with other Western Mediterranean Areas and Geodynamic Hypotheses"), and was field-leader in differing excursions in Sardinia during the cited Congresses and other Meetings (Società Paleontologica Italiana 2002, GEOSED 2003, XXXII IGC 2004, 84° Congresso della Società Geologica Italiana, Sassari 2008).

E’ was chairman at the congress of the Geological Society of America, Boise, Idaho 2004 (Symposium “Sardinia, Italy and the Development of the Western Mediterranean Basin” with P. Pittau and C. Spinosa), at the Congress IAS 2009 of Alghero (Session TS1: “Sedimentology and stratigraphy of continental Permian deposits”, with J.López-Gómez e M. Durand) and at the Congress FIST Geoitalia Rimini 2009 (Simposio G2: “Evoluzione geodinamica del Sudalpino centro-occidentale dal Permiano al Triassico: sedimentazione e magmatismo dalla fine dell’orogenesi varisica al rifting della Tetide”, with C. Perotti, G. Cassinis e A. Tunesi).



At the DSTA he has taught classes of “Basic Stratigraphy”, “Field Camp” (Corso di Laurea in Scienze Geologiche), “Basin Analysis and stratigraphy” (Corso di laurea Specialistica in Scienze Geologiche Applicate) and “Evolution of the Geosphere” (Corso di Laurea in Scienze Naturali).

In the current Academic year (2011/2012) he teaches the class “Geology I”; beyond the teaching courses he tutored 20 Bachelor or Master Degrees. Within the DISTA of Pavia he has different institutional tasks: Member of Collegio dei Docenti del Dottorato in Scienze della Terra, delegate of the Department in COR and member in internal committees.

He was Visiting Professor c/o the Permian Research Institute, Boise State University, Boise, Idaho (2000), where participated to the stratigraphic analysis of the marine Pennsylvanian-Kungurian sequence, Central Pequop Mountains, Elko County (Nevada), c/o il Departamento de Estratigrafia dell’Università Complutense in Madrid and c/o the TU Bergakademie of Freiberg (2010).









1993: MSc in Geological Sciences c/o Università degli Studi, Milano;

1993-1996: Ph.D. c/o Department of Earth Sciences, Università degli Studi di Parma; Thesis title: "Stratigraphy and basin reconstruction of the Escalaplano and Perdasdefogu Permian basins, SE Sardinia, Italy". Advisors: R. Valloni, G. Cassinis and L. Cortesogno. During the Ph.D he made research stages in the laboratoire de palinologie of Université Pierre et Marie Curie (Parigi) Avisor J. Broutin;

1997-2001: Research activity on the Late Paleozoic continental sequences of Sardinia and the Southern Alps: (1997) Grant of Regione Autonoma della Sardegna; (1998-2000): Post-Doctoral Grant of the European Community in collaboration with the Cagliari University, dealing with Stratigraphy and palynology of some Sardinian and Southern Alps Permo-Triassic sequences.
