The focus of my research program is to develop best practices for delivering technology-based primary and secondary public health interventions, particularly in the area of HIV treatment and prevention. I am currently leading on a number of grants to address this issue, including a study to assess the impact of a peer support intervention on medication adherence among HIV-infected drug-using and non-drug-using adult men, which is currently being adapted for youth with HIV of all genders. I am also leading two pilot trials to test the preliminary efficacy of mobile apps to support HIV testing among at-risk men and ART adherence among stimulant-using men.

Current Research Projects:

  • TechStep:Technology-based Stepped Care to Stem Transgender Adolescent 9/2017 – 8/2021
    • Risk Transmission (PI: Hightow-Wiedman & Sullivan)
      • Description: TechStep is a 2-condition, technology-based randomized controlled trial, with a stepped care approach, among high-risk HIV-negative trans feminine, trans masculine, and gender non-conforming youth for reducing sexual risk behaviors and increasing PrEP uptake.
        • Funding Source: National Institute of Child and Human Development
        • Position: Protocol Co-chair/Co-investigator on iTech Technology Core
  • Connecting Youth and Young Adults to Optimize ART Adherence: Testing 9/2016 – 8/2021
    • The Efficacy of the YouTHrive Intervention (PI: Hightow-Wiedman & Sullivan)
      • Description: We propose to test the efficacy of an adapted version of the TWM intervention, called Y-TWM, for Y/YALWH. In this 4-year study, 350 Y/YALWH between the ages of 15-24 with problematic ART adherence at baseline will be randomized to the Y-TWM or a HIV information-only control intervention for a 5-month period.
