I'm broadly interested in how humans represent environmental statistics and causal structures. Specific interests include numerical cognition (current work), generalized magnitude representations (dissertation), and speech-category acquisition. I'm also interested in development of novel infant methods. I recently finished my PhD in the Department of Brain and Cognitive Sciences at the University of Rochester with Dick Aslin and Jessica Cantlon.

Sept. 28-30. Presented poster entitled "Sources of uncertainty in the approximate number system" at the Domain-General and Domain-Specific Foundations of Numerical and Arithmetic Processing Workshop in Tübingen, Germany.


Jan. 1. Started post-doc at LPP studying factors that affect noise levels in the infant and adult approximate number system.

I am currently a post-doc at the Centre for Cognitive Development, University of British Columbia, working with Darko Odic in the Early Development Group. I did my PhD at the Department of Brain and Cognitive Sciences at the University of Rochester, working with Dick Aslin and Jessica Cantlon and previously did a post-doc in Paris with Véronique Izard and Lola de Hevia. In a former life, I was a pianist, but these days I find myself broadly interested in how humans learn about the causal and statistical structure of the world. Most recently, that has expanded to include numerical cognition, but I've worked on diverse problems related to generalized magnitude representation and distributional learning of phonemes. Before working on statistical learning, I was interested in music and auditory perception. I have an interest in methods development, particularly for use with infants, whether it be for creating new eye-tracking paradigms or extending the analytical toolbox of infant researchers.

Here at the LPP, Véronique Izard and I are working on a project in infants and adults that aims to decompose noise sources that contribute to uncertainty in the approximate number system and how those differ across individuals and across different developmental stages.



Keep your eyes open for my dissertation work, which explored the hypothesis space of generalized magnitude representations. We approached the topic from multiple perspectives, including statistical learning as well as analogical reasoning.


Dick Aslin and I worked toward developing novel, forced-choice eye-tracking paradigms for use with infants. To be continued. . .


I'm interested in how infants learn their native speech categories (phonemes) in an unsupervised fashion. To do this, infants need to solve some complex statistical learning and causal inference problems.
