I am a cognitive psychologist and completed my doctoral degree in the Department of Cognitive and Linguistic Sciences at Brown University in 1992. After a two-year postdoctoral fellowship at the University of California at Berkeley, I took a position on the faculty of the University of Massachusetts Dartmouth. I have been here ever since. Beginning in the early 1990's my work focused on understanding the cognition underlying learning in complex domains. Specifically, it was directed at understanding learning of history, biology and psychology with educational hypermedia. Through my laboratory studies I was able to gain an understanding of some ways in which hypermedia and learner characteristics interact to affect learning outcomes in these domains. More recently, my work has shifted to an exploration of other types of learning technology and to the cognition underlying some forms of memory errors. I served as Associate Dean of Graduate Studies and Research in the College of Arts & Sciences from 2013-2020 and have now returned to my faculty role where I teach General Psychology and seminars in memory errors, research ethics, and epistemology in the age of "alternative facts".
