Brief CV of Sander Weinreb (April, 2017)

Sander Weinreb is presently an Emeritus Scientist at JPL and a Visiting Associate at Caltech. He received the B.S.E.E. and Ph.D. degrees from M.I.T. in 1958 and 1963 respectively. Most of his career has been in the administration or development of instrumentation in radio astronomy. His major accomplishments are the introduction of digital correlation techniques into radio astronomy, the discovery of the first cosmic  molecular radio spectral line (OH), and the introduction of cryogenic transistor amplifiers to radio astronomy.
 
From 1966 to 1988 he led the Electronic Division of National Radio Astronomy Observatory where he was responsible for the design of all electronics for the Very Large Array and all other telescopes operated by the observatory. Since 2006, Weinreb has devoted most of his effort in developments for the international Square Km Array (SKA) project and  mentoring students including the supervision of five Ph.D. students in Electrical Engineering at Caltech.  
 
He has over 200 publications, has served  on many review and visiting committees, is a Life Fellow of the IEEE and has received the Reber Medal, the Jansky Award, and the Weber Prize for contributions to instrumentation in astronomy.His current research activities are in the areas of cryogenic low noise amplifiers and decade bandwidth antenna feeds.
