Undergraduate Students

Nancy Ooi

Nancy Ooi started her academic journey in Fall 2021, focusing on a Bachelor of Arts in Sociology. She is a research assistant investigating the exploitation of children in family social media content.

Her research delves into the legal and policy dimensions of this issue, particularly exploring the privacy concerns and potential harm faced by children involved in such content creation. Utilizing qualitative research methods, Nancy conducts interviews with advocates, technology experts, and law students using snowball sampling to gather comprehensive insights. Her research question is: When family content creators include their children in for-profit content, what are the social, legal, and well-being impacts on their children?​

On June 18, 2024, Nancy testified before the Assembly Standing Committee on Privacy and Consumer Protection in support of SB 764, applying her research to help protect minors used in content creation.  

After pursuing her bachelor's degree, Nancy wants to go to law school, using her diverse academic background to address important social problems.
