I am a Research Staff Member in the Cognitive Computing department at IBM T J Watson Research Center. I have a long-standing interest in the cognitive processes of human learning. reasoning, and language. I have applied my work to a wide range of AI applications. Many of my projects have involved monitoring human behavior, building model of that behavior, and interacting with users based upon that model. My recent work has also involved knowledge extraction from unstructured information and logical reasoning over that knowledge in the domains of regulatory compliance, transportation, and insurance.
At Carnegie-Mellon University, in 1982-1984, I worked on cognitive modeling of programmers and developed an intelligent tutoring system (ITS). At Yale University 1985-1988, I worked in the Artificial Intelligence (AI) Lab on case-based reasoning, and in 1989-1997 at Bell Communications Research (Bellcore) on authoring systems and automated training delivery for operators of computer systems.
I started at IBM Research in 1998 in the Applied Learning Sciences Group where I was a Research Staff Member and then Group Manager. I worked on generating metadata for text and video multi-media learning content and developed software systems to assemble these learning objects into training courses. In 2007, I joined the Social Computing group where I worked on applications of social networking to business, mobile applications for emerging markets, and healthcare patient engagement. Since joining Cognitive Computing Research in 2010, I have worked on personal intelligent agents and man-machine dialogue in physical/virtual environments.
