He is currently researching on Machine Learning at CSI Piemonte (Turin) under a scholarship issued by the ISI Foundation (Turin). Carlo Palmisano took his master degree in Physics at Pisa University and a Ph.D. in Theoretical Physics at University of Turin. He is a specialist of Takagi-Taupin equations and extensively worked on various aspects of Avogadro Constant measurements. At present he has a REG (Research Excellent Grant) at Physics Department of Turin University and is involved in metrological research. Gianfranco Zosi started his activity on the re-determination of the Avogadro constant at Istituto Nazionale di Ricerca Metrologica (INRIM) in 1970 and continued the same line of research at  Physics Department of Turin University until his retirement on 2010. He was member of the ad hoc Working Group on Avogadro constant, established at the Bureau International des Poids et Mesures (Sèvres). Show Less
