Welcome to the Technology, Teens, and Families Lab!
Our lab was established in 2022, directed by Dr. Xiaoran Sun, Assistant Professor in the Department of Family Social Science at the University of Minnesota.
We use innovative data and methods to study the interplay among technology, adolescent development, and family systems.
Recent Projects

This is a NIMH-funded project that aims to identify adolescents' social media management strategies.
Family Screenome Study
We study how adolescents and their parents use smartphones, and how their smartphone use impacts their family relationships and well-being.
Machine Learning for Family Research
How we use machine learning to advance discoveries in developmental and family research.
