Thomas Felix Rosenbaum (born February 20, 1955) is an American condensed matter physicist, professor of physics, and the current president of the California Institute of Technology (Caltech).

[4] His contributions range from boosting diversity in STEM through fellowships and research funding opportunities, to establishing a number of initiatives through the largest campaigns in Caltech's history.

[8] During the height of the Cold War, Rosenbaum was inspired by the Apollo program and the Moon landings to pursue physics as a means to solve the world's problems.

[citation needed] Rosenbaum is an expert on the quantum mechanical nature of materials—the physics of electronic, magnetic, and optical materials at the atomic level—that are best observed at temperatures near absolute zero.

[15][16] He established the nature of the metal-insulator transition in doped semiconductors and correlated materials,[17] and demonstrated macroscopic anisotropy of non-s-wave superconductivity in heavy fermion compounds.

[6] Alongside his wife, materials scientist Katherine Faber, Rosenbaum has been instrumental in establishing numerous graduate fellowships and research funding opportunities.

[26] This fellowship, designed to enhance the representation of women in STEM fields, offers summer research support to graduate students and diversity in the sciences.

This fellowship underscores Rosenbaum's dedication to academic freedom, providing graduate students the flexibility to potentially adjust their research paths based on unforeseen results.
