This is my old PhD student web site. I left my PhD program to found Context Relevant, now known a Versive. After
Context Relevant, I
went on to found SkyEye.ai (acquired) and LOA Solutions Inc.. I also helped out Tim Novikoff with Fly Labs, which was
acquired and
integrated into Google Photos.
This web site was created while I was a student in Information Science Ph.D. at Cornell
University where I analzyed terabyte scale data sets to enhance web search systems. My training
is in machine learning, natural language processing, statistics, human computer interaction, economics, public policy, and political science.
In addition to work on web search, I use the methods developed in my dissertation for investment analysis, arbitrage opportunity discovery, and statistical arbitrage. I also have an avocation for cooking with data.
I enjoyed working with other students on diverse projects with an underlying component that requires machine learning
for a subjective or fuzzy problem. Fun student experiments included Seamless Receipts, Twitter Search for Emotional Content and Augmented
reality on mobile devices.
