MIT’s Laboratory for Nuclear Science Welcomes Jesse Thaler, Ushering in an AI-Driven Era

A New Vision for Fundamental Physics at MIT

At a glance, A significant leadership transition is underway at the Massachusetts Institute of Technology’s renowned Laboratory for Nuclear Science (LNS). Effective August 1st, Professor Jesse Thaler has been appointed as the new director, succeeding Professor Bolek Wyslouch, who steered LNS for the past decade. Thaler, a distinguished theoretical particle physicist, is set to infuse LNS with his pioneering expertise in combining quantum field theory with machine learning, heralding a new chapter focused on AI-driven discovery in fundamental physics.

Meanwhile, Nergis Mavalvala, dean of the MIT School of Science, highlighted Thaler’s impactful contributions. “In his research, Jesse has done pioneering work on particle jets at the Large Hadronic Collider and is a leader in combining AI and machine learning with fundamental particle physics,” Mavalvala stated, emphasizing that Thaler’s collaborative research approach will be instrumental as science enters this new era of AI-powered exploration.

Pioneering the Intersection of AI and Physics

Thaler’s appointment comes with a strong background in bridging these two critical fields. He holds the esteemed position of William and Emma Rogers Professor of Physics within the MIT Center for Theoretical Physics – a Leinweber Institute (CTP-LI).

Since 2020, he has served as the inaugural director of the National Science Foundation (NSF) AI Institute for Artificial Intelligence and Fundamental Interactions (IAIFI), an initiative recently renewed for another five years. Professor Mike Williams will now take the helm at IAIFI.

In practical terms, The integration of AI is not just a personal interest for Thaler but a strategic direction for LNS. The laboratory is actively pursuing new research avenues through the Department of Energy’s Genesis Mission, which explicitly focuses on AI-enabled scientific discovery. Thaler expressed his enthusiasm for this synergy:

“In my own field of particle physics, researchers are developing cutting-edge AI algorithms to handle the data deluge from collider experiments and to perform heroic theoretical calculations. This work has direct implications for discovering new physics, but the algorithms themselves turn out to be valuable well beyond our field. I’m excited to bring LNS into the next wave of discoveries supported by AI-driven capabilities.”

Fostering Interdisciplinary Talent

During his tenure at IAIFI, Thaler championed innovative educational and research programs designed to cultivate talent at the intersection of physics and AI. Collaborating with the MIT Institute for Data, Systems, and Society, IAIFI leadership established a unique doctoral program in physics, statistics, and data science. Additionally, dedicated postdoctoral fellowships were created, providing early-career researchers the freedom to pursue groundbreaking interdisciplinary work.

For example, Thaler sees the profound benefits of this approach. “Giving young scientists space to build connections across domains, universities, and career stages has been transformative within IAIFI,” he remarked, expressing his aspiration to implement similar frameworks within LNS to foster a new generation of interdisciplinary scientists.

The Broad Reach of LNS and CTP-LI

Established in 1946 with an initial focus on nuclear and particle physics, the Laboratory for Nuclear Science has evolved significantly. Today, its research encompasses a wide array of fields, including cosmology, gravity, field theory, and quantum information science.

As LNS director, Thaler will also oversee his home center, CTP-LI, which recently received a historic donation from the Leinweber Foundation. This generous commitment supports the establishment of a network of theoretical physics research institutes, marking the largest philanthropic contribution ever made to this field, according to the Science Philanthropy Alliance.

A Distinguished Academic Path

That said, Professor Thaler’s impressive academic journey began with a BS in math/physics from Brown University in 2002, followed by a PhD in physics from Harvard University in 2006. He then served as a fellow at the Miller Institute for Basic Research in Science at the University of California at Berkeley from 2006 to 2009 before joining the MIT faculty in 2010.
