I left Caltech and joined TRW in 1973. In 1975 I was hired by Sandia National Labs in Albuquerque, NM. I worked at Sandia for 32 years in several R&D and management positions. One of my more interesting Sandia assignments was serving in Washington DC as the Director of Critical Infrastructure Protection for the Department of Homeland Security (DHS) Science & Technology division (2003-2005). I retired from Sandia in 2008. My wife Ellen and I split our time between WA and CO because our 2 sons and their families (8 grandkids) live in those 2 states. In addition to spending lots of time with our extended family, we also do volunteer work and are active in our church.
