[4] Keck left Los Alamos in 1946 and returned to Cornell to complete his studies in nuclear physics, receiving his B.S.
His early interests included high-energy particle physics: Keck carried out pioneering research in photo-nuclear reactions and in spectral radiation from high-temperature shock-heated air.
[4] In 1965, Keck joined the faculty of the Massachusetts Institute of Technology, where he began researching the problem of burning rates and pollutant formation in internal combustion engines.
Among his many life-changing events at Los Alamos was his meeting another physicist, Margaret Ramsey, one of the few women scientists employed on the Manhattan Project, which she joined in 1945.
[4] They have one son, Robert, a senior scientist at the Laboratory of Laser Energetics at the University of Rochester in New York and one daughter, Pat, a sculptor who currently lives in Andover, Massachusetts.
