Laboratory manager at UW-Madison.

I'm interested in children's conceptual development, particularly how they come to understand numerical concepts and principles. I currently work as a lab manager in the Cognitive Origins Lab (Stephen Ferrigno) at UW-Madison. In Fall 2026, I will be joining the Cognitive Contruction Lab (Ben Pitt) at UMass Amherst as a PhD student.

One-to-one numerical reasoning in children and monkeys 2026
We tested monkeys and children and found that cardinal principle knowledge is neither necessary nor sufficient to use one-to-one correspondence cues to make precise quantity discriminations. This challenges most existing accounts of how children learn the relationship between one-to-one correspondence and numerical equality. You can find our Cognitive Development Society poster here.
