1946 - He resumed graduate work at the University of Chicago where, under the inspired guidance of the late Professor Enrico Fermi, he worked toward his doctorate.
1948-1949 - He completed experimental work on the diffraction of slow neutrons in liquids and his doctor's degree was awarded by the University of Chicago.
- He accepted a teaching position at the University of California in Berkeley.
1957 - He was awarded a Guggenheim Fellowship for the purpose of doing studies in the physics of antinucleons at the University of Rome.
1958 - He was appointed Professor of Physics at the University of California, Berkeley.
1959 - Served as Loeb Lecturer at Harvard University.
- Won The Nobel Prize in Physics with Emilio Segrè for their discovery of antiproton.
1960 - Together with Professors Carson Jeffries and Gilbert Shapiro, pioneered the development and use of polarized proton targets to study the spin dependence of a wide variety of high energy processes, including the scattering of pi-mesons and protons on polarized protons, the determination of the parity of hyperons, and a test of time reversal symmetry in electron-proton scattering.
