I
am developing machine learning and statistical approaches for a variety of
applications including genomics and vaccine design. In my early work, I
demonstrated the importance of probability theory in Artificial Intelligence,
developed methods to build what are now called AI bots, and developed methods
to learn graphical models from data including methods for causal discovery.
While
at Microsoft, I developed numerous applications including data-mining tools in
SQL Server and Commerce Server, the junk-mail filters in Outlook, Exchange, and
Hotmail, handwriting recognition in the Tablet PC, text mining software in
Sharepoint Portal Server, troubleshooters in Windows, and the Answer Wizard in
Office.
