Sean M. Carroll

Sean M. Carroll serves as Homewood Professor of Natural Philosophy at Johns Hopkins University with dual appointments in the Department of Physics and Astronomy and the Department of Philosophy. Previously a professor at Caltech, Carroll transitioned to Johns Hopkins to embrace a role explicitly designed for interdisciplinary work bridging physics and philosophy. His academic profile reflects a unique synthesis of theoretical physics and philosophical inquiry.

Carroll's research spans foundational questions in quantum mechanics (particularly advocating for the Many-Worlds interpretation), the nature of time and entropy, cosmology including dark matter and dark energy, and the relationship between fundamental physics and emergent phenomena. He has developed influential frameworks like the 'Core Theory' to explain how everyday physics supervenes on quantum field theory. His recent work explores consciousness from a physicalist perspective and the physics of democratic systems.

His publications reveal a consistent focus on making complex theoretical concepts accessible while maintaining rigorous scientific standards. Carroll's recent papers examine energy conservation in quantum mechanics, the philosophical implications of physical laws, and connections between particle physics and cosmology. He has developed innovative educational content through The Great Courses platform, creating accessible explanations of quantum mechanics, time, and cosmology for general audiences.

At Johns Hopkins, Carroll teaches a first-year seminar on the Physics of Democracy and advanced courses in philosophy of physics, supervising graduate students across both departments. His move represents a deliberate institutional commitment to interdisciplinary scholarship that transcends traditional academic boundaries.
