Sergio Verdú (born Barcelona, Spain, August 15, 1958) is a former professor of electrical engineering and specialist in information theory. Until September 22, 2018, he was the Eugene Higgins Professor of Electrical Engineering at Princeton University, where he taught and conducted research on information theory in the Information Sciences and Systems Group. He was also affiliated with the program in Applied and Computational Mathematics. He was dismissed from the faculty following a university investigation of alleged sexual misconduct. Verdu received the Telecommunications Engineering degree from the Polytechnic University of Catalonia, Barcelona, Spain, in 1980 and the PhD degree in Electrical Engineering from the University of Illinois at Urbana-Champaign in 1984. Conducted at the Coordinated Science Laboratory of the University of Illinois, his doctoral research was supervised by Vincent Poor and pioneered the field of multiuser detection. In 1998, his book Multiuser Detection was published by Cambridge University Press.

Sexual harassment allegations and dismissal from tenured position

A Title IX investigation by Princeton, made public in 2017 by the Huffington Post, determined that Verdu had violated Princeton’s sexual- misconduct policy. Previously, Yeohee Im, a graduate student at Princeton, reported Verdu for sexual harassment. According to the Princeton Dean of Faculty, there were allegations that Verdú had also harassed others, but only the one student was willing to make a formal complaint. Verdú denied the findings of the investigation, stating: "The university advised me not to reply but I categorically deny that there were any advances or any sexual harassment." He was subsequently dismissed from Princeton University as of September 22, 2018, following further consideration by the university, which said that "an investigation established that Dr. Verdu violated the university's policy prohibiting consensual relations with students, and its policy requiring honesty and cooperation in university matters". Verdu appealed the decision in the District Court. According to the materials of the United States Court of Appeals for the Third Circuit: "Verdu states three theories under which Princeton discriminated against him: erroneous outcome, selective enforcement, and retaliation." The District Court dismissed Verdu's complaint.

Awards and honors

His papers have received several awards: He served as president of the IEEE Information Theory Society in 1997. He was the founding editor-in-chief of the journal Foundations and Trends in Communications and Information Theory.
