Andrea Saltelli (born August 26, 1953, in Rome, Italy) is an Italian scholar specializing in quantification using statistical and sociological tools. He has extended the theory of sensitivity analysis to sensitivity auditing, focusing on physical chemistry, environmental statistics, impact assessment and science for policy. He is currently Counsellor at the UPF (Universitat Pompeu Fabra) :ca:UPF Barcelona School of Management.
Biography Saltelli earned his degrees in inorganic chemistry from Sapienza University of Rome in the summer of 1976. He then worked at the Italian Nuclear Authority ENEA and, for one year, at the Argonne National Laboratory in the United States. From 1992 to 2015, he worked at the Joint Research Centre of the European Commission, leading a team dedicated to econometrics and applied statistics from 2005. Between 2016 and 2020, he held the position of associate professor at the Centre for the Study of the Sciences and the Humanities (Senter for vitenskapsteori) at the University of Bergen.

Andrea Saltelli has collaborated with Silvio Funtowicz, Jerome R. Ravetz and Jeroen van der Sluijs on the theories and applications of post-normal science.Andrea Saltelli, Lorenzo Benini, Silvio Funtowicz, Mario Giampietro, Matthias Kaiser, Erik Reinert, Jeroen P. van der Sluijs, 2020, The technique is never neutral. How methodological choices condition the generation of narratives for sustainability, Environmental Science and Policy, Volume 106, Pages 87-98. He has also worked with the Belgian sociologist Paul-Marie Boulanger on the application of Niklas Luhmann's theories to the reproducibility crisis in scientific researchA. Saltelli and P.-M. Boulanger, "Technoscience, policy and the new media. Nexus or vortex?," Futures, vol. 115, p. 102491, Nov. 2019. and to the COVID-19 pandemic.P.-M. Boulanger and A. Saltelli, "Pandemic Luhmann," SSRN Electron. J., May 2020. Furthermore, Saltelli has collaborated with the Norwegian economist Erik Reinert on themes related to quantification in economics,Erik Reinert, Sylvi Endresen, Ioan Ianos, and Andrea Saltelli, 2016, "Epilogue: The Future of Economic Development between Utopias and Dystopias", in Handbook of alternative theories of economic development, Edited by Erik S. Reinert, Jayati Ghosh, and Rainer Kattel, Elgar Publishing, see here for the working paper version. and with Daniel Sarewitz on the post-truth debate.
Sensitivity auditing In an interview for 'The Corbet Report',J. Corbett, "Interview 1424 – Andrea Saltelli on The Crisis of Science," The Corbett Report, 2019. Saltelli shared his early fascination with generating quantified evidence through statistical or mathematical modelling, highlighting his concern over how easy it is to produce poor-quality evidence, if not to manipulate data or deceive with numbers. This concern drove his engagement with issues in the fields of epistemology, philosophy of science, and science for policy surrounding the responsible production of data.
This same concern led him to extend the theory of sensitivity analysis to sensitivity auditing, which aims to assess the entire process of knowledge and model generation, including explicit or implicit assumptions, interests, stakes and motivations on part of the developers.Saltelli, A., van der Sluijs, J., Guimarães Pereira, Â., 2013, Funtowiz, S.O., What do I make of your Latinorum?
