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.
At Carnegie-Mellon University, I worked with Dr. John Anderson on cognitive modeling of programmers and developed an early intelligent tutoring system (ITS). At Yale University, I worked in the Artificial Intelligence (AI) Lab on case-based reasoning, and at Bell Communications Research (Bellcore), I worked in the Artificial Intelligence Group in Piscataway, NJ on intelligent tutoring for operation of complex computer software systems and later in the Information Sciences group in Morristown, NJ on personalization and software agents.
I started at IBM Research in 1998 in the Applied Learning Sciences Group where I was a Research Staff Member and later a manager. I developed a summarization system for online discussions and an educational assessment tool for distance learning. Later, I led a project funded by the Department of Homeland Security Advanced Research Projects Agency to develop text and video analysis of multi-media learning content. I also developed Dynamic Learning Experience (DLE), a software system that assembled learning objects into a progression. In 2007, I joined the Social Computing group where I worked on social visualizations of business processes, mobile phone applications for emerging markets, and healthcare patient engagement. Since joining Cognitive Computing Research, I have worked on personal intelligent agents, man-machine dialogue in physical/computational environments, knowledge extraction from unstructured information in the domain of geology, and logical reasoning.
