This is the personal home page of David M. Gay. At present, it is mainly a place from which to download some things related to my late wife Tanner.

I am a co-author of the AMPL modeling language. For more on AMPL, see the AMPL web site.

Tanner's memorial service was held on 15 October 2021. It can be "replayed" here.
