Charles M. (Matt) Bradford

  • B.S. Physics, Stanford University. (1994)
  • Ph.D. Experimental Astronomy, Cornell University, Advisor: Prof. Gordon Stacey. (2000)

Research Interests
  • The properties and energetics of the interstellar medium in galactic nuclei and regions of active star formation.
  • Far-IR - millimeter wave spectroscopic probes of the gas conditions in the Galaxy, nearby galaxies, and at high redshift.
  • Novel ground-based instrumentation to facilitate sensitive new spectroscopic measurements at the Earth's best submillimeter and millimeter-wave sites.
  • Development of technology to realize the astronomical potential of cryogenic orbital far-IR - millimeter wave observatories.


Z-Spec Icon Z-Spec
Z-Spec is a novel millimeter-wave grating spectrometer for observing galaxies throughout cosmic time.

BLISS for SPICA is a US-built mid- to far-infrared spectrograph for the Japanese-led SPICA mission.

Herschel Icon Herschel
The Herschel Space Observatory is a space-based telescope that studies the Universe in the light of the far-infrared and submillimeter portions of the spectrum.
