en.wikipedia.org/wiki/Duncan_Haldane

Contemporary institutional sources distinguish between members and foreign associates of the U.S. National Academy of Sciences, and they identify Haldane as the latter.

• Princeton University’s 2017 announcement says the Academy elected David Huse as a new member and F. Duncan Haldane as a foreign associate.
• The Lindau Nobel Laureate Meetings CV also says Haldane is a Foreign Associate of the US National Academy of Sciences.

Because the article calls him a "member" instead of a "foreign associate," it misstates the specific honor he received in 2017.

This date range conflicts with multiple authoritative biographies.

• The Lindau Nobel Laureate Meetings CV states that Haldane was assistant professor of physics at the University of Southern California from 1981–85, then joined the technical staff at Bell Laboratories from 1985–87.
• Haldane’s own Nobel autobiography says that he received an offer to join Bell Laboratories the next year, took a leave of absence from USC, and then accepted a position at UC San Diego starting at the beginning of 1987.

So the article’s claim that he remained at USC until 1987 is inconsistent with sources showing he left USC in 1985 and spent 1985–87 at Bell Labs.

The article says Haldane was appointed associate professor in 1981, but reliable biographical sources show that 1981 was the year he became an assistant professor at USC.

• The Lindau Nobel Laureate Meetings CV gives his USC appointment as assistant professor of physics (1981–85).
• Haldane’s Nobel biography likewise describes his move from France to the US for a USC faculty position and later says he took leave from USC to join Bell Labs, before moving to UC San Diego in 1987.

Because 1981 is documented as the start of his assistant professorship, the statement that he was appointed associate professor in 1981 is contradicted by the available authoritative biographies.

Multiple authoritative sources contradict both the start and end dates in this sentence.

• The Lindau Nobel Laureate Meetings CV says Haldane served as professor of physics at the University of California, San Diego (1987–90).
• Haldane’s Nobel biography says he accepted a position at UC San Diego starting at the beginning of 1987 and stayed until mid-1990.
• The Nobel facts page likewise says he has been at Princeton since 1990, which is incompatible with remaining at UC San Diego until February 1992.

So the article’s claim that he joined UC San Diego in July 1986 and remained there until February 1992 is contradicted by consistent biographical sources placing his UCSD period in 1987–1990.
