Bio

I am a Principal Scientist and President of Psychometrix Associates, Inc. and a Visiting Lecturer at the College of Information and Computer Sciences - U.Mass.-Amherst. I founded Psychometrix in 1995, to pursue research in computational models of emotion. I am interested in modeling both the cognitive processes mediating emotion generation, and the processes mediating the variety of biases that emotions exert on attention, perception and the cognitive processes involved in decision-making. The primary focus of this work is to improve our understanding of the mechanisms that mediate affective biases, and to gain a deeper understanding of human decision-making and behvioral chioces, as well as the nature of affective disorders and the mechanisms of action in psychotherapy. Applications of this research exist in affect-adaptive decision-aiding and training systems, serious gaming and affective agents.

This research is conducted within the context of a cognitive-affective agent architecture (MAMID), which implements a generic methodology for modeling the interacting effects of a variety of factors that influence attention, perception and cognitive processes. These behavior moderators include not only emotion but also a range of personality traits and physiological states such as fatigue.

My prior work included: decision-aiding systems, cognitive modeling, visualization and GUI design, knowledge elicitation, and model-based reasoning in expert systems.

I was born in Prague, Czech Republic. I received my BS in Biochemistry from Virginia Tech, MS from The Ohio State University in Computer Science, and PhD in Computer Science from the University of Massachusetts-Amherst. Prior to founding Psychometrix Associates, I was a Senior Scientist at Bolt Beranek & Newman, Cambridge, MA.
