Brief Bio

45+ years at NASA Goddard Space Flight Center; 30+ of those with SAIC. I've been supporting the NASA Ocean Color program since 1992, and have been SAIC Program Manager since 1998.

Prior to that, I worked on the Cosmic Background Explorer (COBE) mission from 1986 through 1991, and in the Flight Dynamics Facility (FDF) from 1978 to 1986.

Current Projects
