I am a Senior Research Scientist and manager of ad auction
development at
CombineNet. I am passionate about
developing innovative electronic marketplaces that have real
impact on the world.  I have extensive experience working at
the intersection of theory and implementation of electronic
markets, using techniques from economics, artificial
intelligence
, and optimization.  

Currently I am working on a highly scalable system for
optimally matching campaigns to inventory in expressive
advertising auctions. The system scales to an unprecedented
numbers of bidders and attributes, and supports a much
more expressive bidding language than standard advertising
auctions.

I received my  PhD in computer science and engineering from
the University of Michigan in 2001 for my work in market
protocols for decentralized supply chain formation (
pdf). A
selection of my papers are available online.
