SCIENTIFIC ACTIVITY

• Digital signal processing & Advanced spectral and statistical time-series analysis applied to geophysics, macroeconomics, biological systems, with both classical and advanced spectral methods (MEM, MTM, BT correlogram, WT, PCA, EEOF, SSA, M-SSA)
• Complex networks theory applied to biology (plants taxonomy and classification on the basis of their seed dispersal and volatile organic compounds emissions); to socio-economic systems (distress propagation in the framework of financial contagion in networks of banks); and to online social networks (Facebook echo chamber dynamics; Twitter data as fingerprints of economic and social interactions)
• Paleoclimatology & Geophysics: meteorites and cosmogenic radionuclides (gamma-ray spectroscopy with HPGe + NaI detectors); extreme events analysis (historical volcanic records); sea surface temperatures (SSTs) proxies (especially, foraminiferal d¹⁸O, d¹³C) from marine sediments samples (Mediterranean area)
• Medical physics & Radiation dosimetry: hadrotherapy and BNCT (Boron Neutron Capture Therapy);  treatment planning system (TPS) benchmarking and validation
