About Me

I’m an engineering manager living in Houston, Texas. I spent the first 20 years of my career in defense and intelligence, and for the past 8 years I’ve worked on projects at NASA’s Johnson Space Center.

In my spare time I develop software applications, and for many years I ran both a personal blog and a group blog on critical thinking and civility. This homepage is my place to collect up some of my more useful critical thinking materials, and make some of my software apps available for download.
