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.
