I live in Moraga, CA with my wife Laura. I spent 31 years as a staff scientist at Lawrence Berkeley National Laboratory before recently retiring. I am currently working as a consultant. Laura is a music teacher with Walnut Creek School District. We have two children, Tim and Sarah. Tim graduated from UC Irvine a couple years ago and is going to law school at Loyola in Los Angeles. Sarah will graduated from Southern Oregon University last year, and is currently living at home while trying to figure out the next chapter.
