Omar M. Yaghi (Arabic: عمر مونّس ياغي, born February 9, 1965) is a Jordanian-American Nobel chemist. He was born in Amman, Jordan, to a Palestinian refugee family. He is a professor of chemistry at the University of California, Berkeley. Yaghi is known for creating reticular chemistry, which is a new field of chemistry. It focuses on the stitching of molecular building blocks together by strong bonds to make open frameworks.
His most well-known work is in the design and production of new classes of compounds known as metal-organic frameworks (MOFs). He studied at the University of Illinois at Urbana-Champaign.
In 2017, he won the Albert Einstein World Award of Science. In 2018, Yaghi won the Wolf Prize in Chemistry.
Yaghi was awarded the 2025 Nobel Prize in Chemistry with Richard Robson and Susumu Kitagawa, for his work in reticular chemistry and for the creation of metal–organic frameworks (MOFs).
