Chris Walker is
a professor at the University of Arizona with over 20 years
of experience designing, building, and using state-of-the-art
receiver systems for radio astronomy. He has advanced degrees
in both astronomy and electrical engineering and has worked
in industry (TRW Aerospace and JPL) as well as academia. As
a Millikan Fellow in Physics at Caltech, he led the effort to
develop the first low-noise, SIS waveguide receiver above 460
GHz. At the University of Arizona he began the Steward Observatory
Radio Astronomy Lab (SORAL), which has become a world leader
in developing leading-edge submillimeter-wave receiver systems.
SORAL constructed the world’s first 810 and 345 GHz heterodyne
array receivers for radio astronomy. These instruments were
multi-institutional efforts, with key components coming from
JPL, several universities, and industrial partners.
