I am a research manager in the area of software engineering. My research interests are in how combinations of static/dynamic program analysis, model checking and theorem proving techniques can help improve the correctness and reliability of programs. See my papers for more details.

I grew up in Summit, NJ, where my claim to fame was writing a game for the Apple ][ called Falcons in 1980 with high school pal Eric Varsanyi (see The Giant List of Classic Game Programmers). I attended Cornell University (B.A. 1987), and the University of Wisconsin-Madison (Ph.D. 1993). From 1993-1999, I was at Bell Labs in Naperville, IL in the (now defunct) Software Production Research Department. After 12 years as a Midwesterner, I had had enough. Now I live in Mercer Island, WA. I have sung in various Unitarian Universalist choirs, play e-bass (mainly jazz, blues, some rock 'n roll) and piano. I now play in a band called the "The Middle Third".
