I am a psychologist studying how human minds are equipped to extract useful information from confusing input.
We get information about the world from a variety of imperfect sources: the sensory experience of hearing a muffled voice, memories that feel like dreams, or testimony from our peers. How do we extract useful information from this confusing input?
I study the cognitive and social tools that humans leverage to learn about the world, focusing on childhood. My work uses behavioural experiments and individual differences, combining methods and theoretical approaches from psychophysics, linguistics, and computational cognitive science.
In my main line of work, I study metacognitive reasoning about confidence: the way we signal to ourselves that something seems trustworthy. Here's a blog post I wrote about how confidence impacts learning. I also maintain a line of research on children's social reasoning, including how children select good teachers and learn to be teachers themselves.
I am currently a postdoctoral fellow at the University of California, Berkeley working with Drs. Celeste Kidd and Jan Engelmann, sponsored by a SSHRC Postdoctoral Fellowship. I completed my PhD at the University of British Columbia working in the Centre for Cognitive Development with Dr. Darko Odic. Here's a precis of my dissertation. I also hold an MASc and a BA at the University of Waterloo working in the Child Cognition Lab with Dr. Ori Friedman.
I also work with businesses and organizations by contributing scientific insights about child development, learning, and research design. I am passionate about working with clients using science-based practices and cutting-edge research findings. Please email me for more information.
Children are sensitive to subtle changes in their confidence, and this develops independently of related abilities.
Can children accurately evaluate their own confidence?
Children easily compared confidence states from independent perceptual processes.
Do children reason about confidence through a single process?
Individual differences in confidence reasoning correlated across independent perceptual domains.

Having a fine-tuned sense of confidence isn't linked to math skills.
How does reasoning about confidence help us learn?
Metacognition and Learning
Children reason about their own confidence differently than they reason about others' confidence.
Journal of Experimental Child Psychology
Children interpreted information presented in pretense as generally true in the real world.
What function does pretense play in childhood?
