===About the study===
Hi there! Welcome to the CoTwins Lab page. We are a team of researchers at the University of Minnesota and the University of Colorado-Boulder who study behavior genetics, psychology, and computer science. 

The goal of our study is to understand better how young adults change, in their personality, their friendships, their activities, and their environments. We are also interested in how young adults may use substances during this time, including nicotine, alcohol, and marijuana, and ultimately this information can be used to prevent and treat addiction disorders. Our study uses novel smartphone technology to assess these factors in twin participants over the course of several years.

No one has ever conducted a study like CoTwins, and we hope you enjoy learning more about our study! This primary purpose of this webpage is to serve as a way for our team to document and track our progress over the course of this 4-year longitudinal study.
