This sentence is correct about Scholze’s Clay fellowship, but incorrect about the institute’s location.

• Clay’s official profile for Peter Scholze says he "was appointed as a Clay Research Fellow for a term of five years beginning July 2011," confirming the fellowship itself.
• But Clay’s own 2013 annual report says that during this period CMI "run its scientific program from offices in the Mathematical Institute at Oxford" and "remains a US corporation, now with its headquarters in Providence, RI." The same report also refers to its former "offices at Bow Street in Cambridge, MA."
• Separately, the official Leopoldina member profile for Scholze lists his 2011–2016 position as "Fellow, Clay Mathematics Institute, Cambridge, USA."

So the article’s wording placing the Clay Mathematics Institute "in New Hampshire" is not supported by the institute’s own records and is contradicted by official sources identifying Cambridge/Oxford/Providence instead.
