I'm Principal Investigator for the DAML Integration and Transition effort and a Principal Engineer at BBN Technologies.

I'm also the author or co-author of a number of DAML tools:

• DAML Ontology Library

• HyperDAML
• DAML DB

I've previously worked on a number of other DARPA programs:

• CASES
• ARPI
• DART

I'm also one of the principal developers of BBN's Cronus/Corbus Distributed Computing Environment.

I worked for BBN in Cambridge, MA from 1984-1992. In 1992, I became a telecommuter, based in Portland, OR (1992-1995), Spokane, WA (1995-2004), and Ann Arbor, MI (2004-present).

I have a BS in Computer Engineering from Stanford University and did graduate work in Computer Science at the University of Rochester.

My wife Nancy and I have 2 children: Jason (born in 1997) and Noah (born in 1999).
