My research aims to chart the development of risk-taking and decision making during the preschool years, while taking special note of individual differences. To do this, I implement a combination of behavioral and computational methods.

Child Risk Utility Measure
The Child Risk Utility Measure (CRUM) is a touchscreen application which enables us to assess individual differences in young children’s risk propensity. The CRUM respects the cognitive limitations of three- to six-year- old children. In this task, children try to help Cookie Monster take cookies from a cookie jar without Oscar waking up. However, the chances of Oscar waking up increase along with the number of cookies on the plate.

The game Shima was developed as part of the 2017 Virtual Reality BrainJam Hackathon during the 2017 Games for Change Festival. Shima is a virtual reality measure of risk propensity. In this game, you are a photographer on an island inhabited by new species of animals. Your goal is to get as close as you can to each animal and take their picture. The closer you get, the more points you get. But if you get too close, the animal gets scared and runs away. We look forward to collecting data with measure at the Brain Game Center at UC Riverside.

I grew up outside of Boston, MA. I completed my undergraduate education in Brain and Cognitive Sciences at the University of Rochester. I am a strong supporter of open science. Other than science, I enjoy running, hiking, baking, and folk music.
