Andrea Zaccaria is a researcher at the Institute for Complex Systems-CNR in Rome. He received his Ph.D. in Physics at the “Sapienza” University of Rome, where he applied concepts and methods borrowed from statistical physics and the physics of complex systems to the study of financial markets. As a member of the research and development group of SoSE Spa, one of the main Italian fiscal agencies, he developed a machine learning algorithm to classify taxpayers and detect tax evasion. In his current role with ISC, Andrea is exploring the use of complex networks methodologies, algorithmic tools, and machine learning in the field of economics. This activity led Andrea to the appointment as a consultant at public and private organizations, including the cybersecurity startup Sharelock (www.sharelock.ai), the Joint Research Centre of the European Commission, and the International Finance Corporation-World Bank Group (www.ifc.org).
