My current research focuses on concepts of individual entities (individual people or dogs or chairs), mathematical concepts (e.g., natural numbers or groups), and types of reasoning related to these concepts (typically causal or mathematical reasoning). For a more complete description of the research going on in this lab, check the "Projects" section of this web site.

My research concerns how people represent necessity in causal relations. While certain causal relationships (rain leads to a good crop season; flipping a switch leads to a lightbulb turning on) are fairly easy to imagine as otherwise, we seem to represent others as less incidental and more fundamentally necessary (solid objects do not co-penetrate each other, non-viscous liquids conform to their containers). I'm interested in how does this distinction develops, and how it might bear on our psychological models of causal reasoning

My research focuses on individual concepts (i.e., our concepts of individual entities, like your Uncle Fred, or your cat Fido, or your favorite frying pan). More specifically, I am interested in how we individuate and re-identify particular objects over time (e.g., how do we tell that Uncle Fred today is the same man that we saw at the end of Summer last year?) and in how we reason about material composition (e.g., why, for instance, do we judge that certain atoms compose a molecule but that my computer, your nose and Yankee stadium fail to compose anything at all?).

My research interests are related to causal reasoning and causal directionality. The relationship between cause and effect is asymmetric (i.e., causes precede effects, not vice versa). As such, reasoning from cause to effect (predictive reasoning) and from effect to cause (diagnostic reasoning) entails the consideration of different relational variables. I’m interested in the differences between these two processes and how they can inform models of causal reasoning.
