[3] His father, a physicist, read astronomy books to Cullers as a child, influencing the boy's later aspirations.
Kent Cullers worked for NASA's Search for Extraterrestrial Intelligence (SETI) program upon graduating from Berkeley.
He developed advanced computer algorithms for detection of continuous and pulsed signals originating from distant Earth-like planets.
From 1990 to March 1994, he was the signal detection subsystem manager for the High Resolution Microwave Survey (HRMS) Project at NASA Ames Research Center, Moffett Field, California.
From 1993 to March 1994, Cullers led the SETI Research & Technology effort and managed the upgrading and replication of all the digital data processing equipment for HRMS.
