I am currently a post-doc at the Laboratoire Psychologie de la Perception, Université Paris Descartes, working with Véronique Izard in the Perception-Action Group. I recently finished my PhD at the Department of Brain and Cognitive Sciences at the University of Rochester, working with Dick Aslin and Jessica Cantlon. 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.

DEVELOPMENT OF NUMERICAL COGNITION
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.
GENERALIZED MAGNITUDE REPRESENTATIONS
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.
