Until 2023, Piet Hut was head of the Program in Interdisciplinary Studies at IAS. Hut's main research theme is “the Nature of Reality,” as seen through the lenses of Math, Matter, and Mind. Some subthemes are: for Math, “Algorithms and Foundations”; for Matter, “Physics and Biology”; and for Mind, “Phenomenology and Contemplation.” Hut’s main research background is in computational astrophysics, with asteroid “17031 Piethut” named in his honor. He is one of the co-founders of the Earth-Life Science Institute at the Tokyo Institute of Technology. His current book projects include a Typology of Novelty, a study of origins, starting with the origin of the biosphere as the archetype for the origin of a self-organizing complex system, in collaboration with Eric Smith, and a comparative study of European science and philosophy with empirical studies of the mind in other cultures, in collaboration with Alex Englert.
