Research Summary

Dr. Fields’s research uses mixed methodologies to understand and reduce HIV disparities among adolescent and young adult African American gay and bisexual men, as well as other men who have sex with men (MSM).

He was awarded a Johns Hopkins Center for AIDS Research Scholar Grant for Faculty Development, an award intended to strengthen his ability to secure independent National Institutes of Health research funding.

Dr. Fields’s study–entitled “Geosocial Networking (GSN) Applications: An Avenue for Innovative Target HIV Control Strategies among Young Black MSM”–focuses on understanding how GSN smartphone applications used as sex partner-meeting venues among MSM may be shaping sexual networks among young black MSM.

It also will examine how public-health practitioners can use these applications to identify and access the sex networks with the greatest risk for ongoing HIV transmission.
