The Faculty History Project documents faculty members who have been associated with the University of Michigan since 1837. Key in this effort is to celebrate the intellectual life of the University. This Faculty History Website is intended as a component of the effort to document the extraordinary academic achievements of Michigan’s faculty in building and sustaining one of the world’s great universities. It provides access to a comprehensive database of information concerning the thousands of faculty members who have served the University of Michigan.

The Bentley Historical Library serves as the official archives for the University.


Yukio Tomozawa
Regents' Proceedings 292

Yukio Tomozawa, D.Sc., professor of physics in the College of Literature, Science, and the Arts, will retire from active faculty status on May 31, 2004.

Professor Tomozawa received his B.Sc. and D.Sc. degrees from Tokyo University in 1952 and 1961, respectively, and he did post-doctoral work at Cambridge University, the University College London, the University of Pisa, and the Institute for Advanced Study. He joined the University of Michigan faculty as an assistant professor in 1966 and was promoted to associate professor in 1968 and professor in 1972. An exceptional researcher, Professor Tomozawa's work spans a wide range of issues in fundamental interactions, including structural analyticity, consequences and imposition of symmetries, and new physics phenomenology. Early in his career, he published several influential articles that investigated partially conserved axial vector currents, which produce rigorous results at low energies for pion-nucleon scattering and proton decay matrix elements.

Professor Tomozawa's contributions in this area will stand the test of time. He turned his focus next to studying the nature of quark confinement due to psi spectroscopy, and he developed a new understanding of potentials in quantum chromodynamics. More recently, Professor Tomozawa shifted his interests to neutrino, cosmological, and gravitational physics. He proposed new theoretical ideas in these areas and designed and carried out some of the resulting experimental studies himself. Based on his research throughout the years, Professor Tomozawa has published more than 80 articles in physics journals and conference proceedings. Professor Tomozawa is a dedicated teacher. He initiated an undergraduate course in general relativity, and the classes he taught were very popular among students. He supervised six Ph.D. dissertations and was invited as a visiting professor to many international research centers.

The Regents now salute this distinguished scholar by naming Yukio Tomozawa professor emeritus of physics.
