Dr. Fields is an Assistant Professor in the Division of General Pediatrics and Adolescent Medicine at Johns Hopkins School of Medicine and is a board-certified pediatrician and board-eligible adolescent medicine subspecialist. He is a physician researcher with clinical and research interests in the treatment and prevention of HIV and other sexually transmitted infections (STIs) in adolescent and young adult populations. His research focuses on using mixed methodologies to understand and reduce HIV disparities among adolescent and young adult Black, gay, bisexual and other men who have sex with men (MSM). His qualitative research has focused on the social context of individual risk behavior among young Black MSM. He currently has an NIH funded grant employing both qualitative and social network analysis to understand the role of physical and internet-based sex partner meeting venues on sexual networks and HIV risk among young Black MSM in Baltimore. He also works in the Center for Child and Community Health Research on their collaborative work with the Baltimore City Health Department to identify high HIV transmission areas among MSM in Baltimore City through the use of HIV and STI surveillance data and to enhance existing testing and linkage to care strategies to increase case finding among those at highest risk.
As a physician, Dr. Fields provides primary and subspecialty care in the Adolescent Health Clinic and HIV care to youth living with HIV in the Intensive Primary Care Clinic. Both clinics are part of the Harriet Lane Program of the Johns Hopkins Children’s Center.
