Alessandro Strumia (born 26 December 1969)[1] is a physicist of the University of Pisa.
Education
Strumia obtained his PhD in 1995 at the University of Pisa, where his doctoral advisor was Riccardo Barbieri. His thesis was titled "Supersymmetric unification".[1]
Career
Strumia has been described as being a "hot shot professional" within the physics community.[2] His research specialization is in physics beyond the Standard Model.[1] He joined CERN's theory division as a fellow in 2000, and as a member of the CMS Collaboration, he was a credited coauthor on the paper which announced the Higgs boson discovery; his primary affiliation was Estonia's National Institute of Chemical Physics and Biophysics.[3] Along with Joseph Lykken and other collaborators, he later proposed the "modified naturalness" hypothesis for the Higgs boson's mass.[4]
After the OPERA experiment reported an observation of neutrinos apparently traveling faster than light, Strumia in collaboration with Gian Giudice and Sergey Sibiryakov showed that superluminal neutrinos would imply some anomalies in the velocities of electrons and muons as a result of quantum-mechanical effects. Such anomalies could be already ruled out from existing data on cosmic rays, thus contradicting the OPERA results.[5][6]
While at CERN in June 2018, Strumia and Riccardo Torre worked on a new set of algorithms with which to evaluate the impact of published scientific research. Basing their investigation on the indices used by Google, they proposed a similar system of ranking scientific output. According to commentators, their conclusions were "intriguing", but possibly subject to "transparency issues".[7] Their field of research has been described as significant, owing to the "simplicity" of current methods of evaluation, which cannot cope with the quantity of research being published at the time. The difference in Strumia and Torres' approach is that they include what they describe as "second-generation" citations in their algorithms. Therefore, not only the original citations of the work are taken into account, but subsequent citations to derivative material also. They named their system PaperRank, in acknowledgement of the influence of Google's PageRank on their work.[7]
Incident at CERN
On 28 September 2018, Strumia gave a presentation at CERN's first Workshop on High Energy Theory and Gender that provoked considerable controversy.[8] Citing an analysis he had performed on data from the InSpire database,[9] he rejected the idea that physics suffers from gender bias against women and claimed that male scientists were victims of discrimination. Strumia cited previous research which points to results commonly referred to as the "Gender Equality Paradox".[10]
He was immediately suspended from working for CERN.[11] CERN removed the slides of Strumia's presentation from its conference website, stating that "CERN considers the presentation delivered by an invited scientist during a workshop as highly offensive and supports the many members of the community that have expressed their indignation". They also state that "[CERN] is a place where everyone is welcome, and all have the same opportunities, regardless of ethnicity, beliefs, gender or sexual orientation.[12][13] Strumia has complained that science is "becoming sexist against men".[11] Jessica Wade, a physicist at Imperial College, London who spoke at the same workshop, rebuked Strumia's claims,[12][13] saying they have "long been discredited"[14] and comparing them to James Damore's controversial memo "Google's Ideological Echo Chamber".[15] CERN suspended Strumia from his "invited scientist" position pending further investigation and both the University of Pisa and the European Research Council announced the opening of ethics investigations into his conduct.[8]
