Research Interests

We study eating behaviors in young children, in particular, how do they develop and how are they related to risk for obesity later in life. We are using techniques such as brain imaging and genetic screening to provide insight into the biological underpinnings of eating behavior and food preferences in children. Also, we are researching the impact of food marketing and branding on these eating behaviors.

  • Eating behaviors in children
  • Neural mechanisms of taste preference and eating behaviors in children
  • Food marketing and childhood obesity
  • Genetic and neural influences in taste in children
