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.

Jesse Thaler joins CACM and AI Institute leaders for virtual panel discussion: Watch the virtual panel discussion hosted by Communications of the ACM on February 1, 2022 to discuss how science and AI are transforming each other, featuring IAIFI Director Jesse Thaler, Anima Anandkumar (NVIDIA Director of ML Research), Vikram Adve (Director, AIFARMS National AI Institute), and Amy McGovern (Director, NSF AI Institute for Research on Trustworthy AI in Weather, Climate, and Coastal Oceanography).

IAIFI researchers’ model-free reinforcement learning system breaks the record for fastest robotic mini cheetah run recorded: Featured in MIT News and NSF Science Now, IAIFI Fellow Ge Yang, Senior Investigator Pulkit Agrawal, and collaborator Gabriel Margolis trained the robot in simulation under variable conditions, which made it more robust when deployed in the real world—a strategy expected to be relevant for making real-time adjustments in the operation of experiments to maximize the physics reach. March 22, 2022

IAIFI welcomes UKRI Centre for Doctoral Training in Artificial Intelligence, Machine Learning & Advanced Computing (AIMLAC): IAIFI hosted 15 AIMLAC students and faculty for an informal workshop March 2 through March 4, 2022, where the two groups shared research and education strategies, and had opportunities for networking. March 4, 2022

Second Round of IAIFI Fellows Announced: The next round of IAIFI Fellows (2022-2025), Denis Boyda, Carolina Cuesta, and Jessie Micallef, will join us later in 2022 and help spark vital interdisciplinary research at the intersection of Physics and AI! January, 28, 2022

IAIFI Senior Investigator Phiala Shanahan receives 2021 Wu-Ki Tung Award for Early Career Research on QCD: Phiala was recognized “for pioneering studies of long-wavelength and nuclear non-perturbative QCD effects in discretized space and time, and for applications of machine learning to lattice field theory.” January 24, 2022

IAIFI Junior Investigator Harold Erbin receives MIT Infinite Expansion Award: Harold was selected as one of the recipients of MIT’s Infinite Expansion Award for 2022 because of his “exemplary service on the IAIFI Early Career and Equity Committee” and being “actively involved in many other IAIFI community building efforts.” January 10, 2022
