Current Research Areas of Interest
Many youth and young adults are exposed to substance use-related content via social media. We are using social media for insights into drug use behaviors, especially use of newly emerging drugs that are increasing in popularity. This information will help us understand how social media can be used for delivering substance use messages to young people.
As more and more people engage with social media, it is important to learn the motivations of individuals who publicly post about their depression, suicidal thoughts, and self-harm struggles via postings on social media. We are seeking to understand why this type of social networking occurs online and how it impacts users’ overall mental health.
There is increasing concern about online communities that promote eating disorder (ED) behaviors. We are exploring innovative strategies for online, accessible, and timely ED-related outreach that could facilitate novel ways to utilize social media in mental health promotion and prevention initiatives.

Conducting investigations into substance use among teens and adolescents using nationally representative datasets (PATH, NYTS, NSDUH)
In this study that is linked, we looked at how social media impacts tobacco and vaping behaviors.
Examining the self‐reported advantages and disadvantages of socially networking about body image and eating disorders
We found that posting/following thin-ideal content on SMPs were motivation/encouragement to engage in a certain behavior, socializing, and information giving/seeking while posting/following thin-ideal content on SMPs were that the content elicits negative/bad feelings.
Leveraging social media to explore the barriers to treatment among individuals with depressive symptoms
We found that those with major depression were more likely to seek out treatment, to report an unmet need for
treatment, and have a higher risk of suicide. Barriers to treatment were more likely to be attitudinal, while participants with mild depression experienced more structural barriers.
