Research Focus
My work has contributed to research areas that are viewed as key enablers for the development of cognitive agents, and for the generalized application of artificial intelligence to complex realworld problems, including mixed-initiative human computer interaction, knowledge acquisition of problem solving expertise from human subject matter experts, knowledge engineering, evidence-based reasoning and assumption-based reasoning. As part of my research work I have also contributed to the development of several successive generations of learning agent shells and of cognitive agents developed with them (Disciple, Cogent).
