The NSF AI Institute for Artificial Intelligence and Fundamental Interactions (IAIFI)

The NSF AI Institute for Artificial Intelligence and Fundamental Interactions (IAIFI, pronounced /aɪ-faɪ/) is one of the inaugural NSF AI research institutes. The IAIFI is advancing physics knowledge – from the smallest building blocks of nature to the largest structures in the Universe – and galvanizing AI research innovation. The IAIFI is a collaboration of both physics and AI researchers at MIT, Harvard, Northeastern, and Tufts. Learn more about our research at the Physics/AI intersection and about our IAIFI Fellows program.


Applications are open for the 2024–2027 IAIFI Fellowship: Our fourth round of the IAIFI Fellowship search is now open. Apply on AJO by October 10, 2023.
