Currently

I’m Susan J. Rosowski Associate Professor of Psychology and a resident member of the Center for Brain, Biology & Behavior at the University of Nebraska-Lincoln. I study decision making, cognition, and well-being in humans and other animals at the Adaptive Decision Making Lab and the Canine Cognition and Human Interaction Lab. I am also a Data Science Mentor at RStudio Academy where I teach data science to teams of learners.
