Personal

I grew up in San Francisco, and went to Lowell High. I did math and computer science at Berkeley, then went to U. of Chicago for my PhD in math.

I met my wife Elissa in Chicago. She taught special education for many years and is now a school psychologist. She maintains the world’s premiere Goat Allergy page.

We spent two years living in Brooklyn while I was working at the CUNY Graduate Center, then moved to St. Louis in 2000. Our two grown up kids Ben and Becca have left home and our two grown up cats Snickers and Lola have not.

I play too little ultimate frisbee and too much Pokémon Go.
