How does this work?
About

My interests include artificial intelligence, distributed systems, neural networks and cognitive science. My career has threaded through academia, government, and industry. I have taught computer science at the University of West Florida. At the Institute for Human and Machine Cognition, he secured and worked on several governmental research contracts. My industry experience spans small start ups, such as BSecure Technologies, Reputation.com, Briq, and Offer Up, to large companies--Electronic Arts (EA) and Google. I've led the Intelligent Systems team at EA that helps game studios find ways to leverage AI and data driven solutions within their games. My applied research topics have included identifying Martian geological formations (for Spirit and Opportunity rovers), modeling ground-based laser marksmen, and computed tomography of debris fields from holograms during armor penetration tests. I have authored seven refereed journal publications, two edited books, six book chapters, and twenty-eight refereed conference papers. I hold thirty four US patents, with another dozen applications in flight. I received my Masters and Ph.D. in computer science from The Ohio State University. My B.A. in computer science is from the University of California, San Diego.
