He graduated from Vassar College with a B.A. in 1981, and from the University of California, Berkeley with a Ph.D. in 1988.
Carlstrom specializes in measurements of the Cosmic Microwave Background, and has led several experiments, including the Degree Angular Scale Interferometer, the Sunyaev-Zel'dovich Array, and the South Pole Telescope.
He is also known for manufacturing the Gunn oscillators used at several millimeter and submillimeter observatories, such as the BIMA array, the Caltech Submillimeter Observatory and the James Clerk Maxwell Telescope. These oscillators produced the local oscillator signal for the observatorys' heterodyne receivers.[2][3][4]
