  • Steven Safren, Ph.D.

    S‌teven Safren, Ph.D., ABPPDr. Steven Safren

    I joined the Department of Psychology at the University of Miami in the Fall of 2015 after 18 years working in the Harvard Medical School system at Massachusetts General Hospital (MGH), where I was the founding Director of the current Behavioral Medicine Service and track Director of the Behavioral Medicine Internship track. During this time I was also an Affiliated Investigator at Fenway Health where I led studies related to HIV prevention for men who have sex with men (MSM). I am a clinical health psychologist with expertise in health-related behavior change and a particular focus on psychosocial (mental health and substance use) comorbidities related to HIV prevention and treatment in both domestic and international settings. I have been PI or protocol chair of 12 federally funded studies (via NIMH, NIDA, and NIAID), and, in addition to studies where I am PI, I have regularly served as co-PI, co-investigator, or mentor on studies related to HIV prevention and treatment.

    I work with other medical illnesses, and I work on cognitive behavioral approaches to managing adult and adolescent ADHD. My international studies have been via the NIAID-funded AIDS networks (i.e. HIV Prevention Trials Network - HPTN, and the AIDS Clinical Trials Network -ACTG), which span multiple countries, via my own NIH-funded studies, and via the work of my mentees K and R level funded studies in India and Africa. Much of my work on HIV focuses on prevention and treatment with men who have sex with men (MSM), though I have worked extensively with other populations including individuals with depression and those who have struggled with substance use disorders. Finally, during my time at MGH, I worked on studies of cognitive-behavioral therapy for ADHD in adulthood and adolescence.

    Currently, my funded work includes a preliminary study involving treating syndemics (intertwined psychosocial problems such as depression, childhood sexual abuse, substance use, interpersonal violence) in HIV-infected individuals with uncontrolled virus, a study on HIV prevention in men who have sex with men in two sites in India, and an effectiveness study on treating depression and improving adherence in HIV-infected individuals in South Africa who have failed first line antiretroviral therapy. Anticipated future studies, based on prior collaborative pilot work, involve pre-exposure prophylaxis (PrEP) adherence in high risk MSM, interventions to reduce crystal meth and increase safer sex (condoms or PrEP) in MSM who use crystal meth, and additional studies addressing syndemics in individuals with HIV and uncontrolled virus.

    Post-Doctoral Fellow‌

    Marc earned his Ph.D. in Counseling Psychology from the University of Miami in 2017, prior to joining the HPAC lab as a post-doctoral researcher. Marc also earned his M.Ed. from the University of Miami. His clinical and research interests include addressing mental and physical health disparities by improving the efficacy and effectiveness of manualized interventions.

    Tiffany R. Glynn, M.S.Tiffany R. Glynn

    Fifth-Year Graduate Student

    Tiffany is a fifth-year graduate student in the Clinical Health Psychology Ph.D. program. She earned a B.S. in Psychology in 2011 from Bridgewater State University and an M.S. in Behavioral and Social Health Sciences from the School of Public Health at Brown University in 2016. Her master's work focused on how minority stress and gender affirmation affect the physical and mental health of transgender women. Before coming to the University of Miami, she worked as research staff at the Brown University School of Public Health in the Center for Alcohol and Addiction Studies and the Alcohol Research Center on HIV for 5 years. At UM, she is part of the HPAC lab (Director: Safren) and also collaborates with the UM NIMH funded AIDS Research Center (CHARM; PI: Safren) and the iCARUS lab in the Department of Public Health Sciences (Director: Carrico). Currently, she coordinates and serves as a clinician on a NIDA-funded R01 multisite randomized clinical trial investigating an HIV-prevention intervention for MSM who use stimulants (Project IMPACT).

    Broadly, her research interests are biopsychosocial health disparities among sexual and gender minorities with an emphasis on substance use and HIV. Currently, she has an R36 award from NIDA to examine how the biological, behavioral, psychological, and social factors interact (a “syndemic”) to drive primary and secondary HIV risk among transgender women in Miami. Tiffany is also co-investigator on a CFAR pilot that explores if feminizing hormone therapy influences the microbiome and biomarkers of cardiovascular risk in transgender women living with HIV. Additionally, she is a co-investigator on a pilot award from CHARM that explores the role of intersectional stigma and resilience in cardiovascular disease among cisgender women living with HIV.
