His research focuses on high energy physics, beyond the Standard Model, studying the flavour of elementary particle, charge conjugation parity (CP) symmetry violations, and the Higgs boson.
In September 2018, Strumia gave a controversial presentation at CERN's first Workshop on High Energy Theory and Gender, where he claimed that male, not female scientists, were the victims of discrimination on the part of universities.
[8] He joined the European Organization for Nuclear Research (CERN)'s theory division as a fellow in 2000,[2] 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.
[11] Marco Cirelli and Alessandro Strumia were amongst multiple teams that used digital photos from a conference presentation by other authors in 2008 in Stockholm for a subsequent publication.
[17] Citing an analysis he had performed on data from the InSpire database,[18] he tested the idea that there is a gender bias against women within the academic circles of physics.
[27] Strumia's talk was condemned in a public letter titled “High Energy Physics Community Statement” on a website called “Particles for Justice” on 2 October.
As of 13 October, it received nearly 4,000 signatures from scientists working in High Energy Physics and related fields, including those of John Ellis, Howard Georgi and David Gross.
[35][36] Following this announcement, Strumia uploaded an unofficial recording of the event on a newly started website, where he claimed that his position had been misrepresented in the media.
