Keith J. Horvath, PhD
The focus of my research program is to develop best practices for delivering primary and secondary mHealth interventions, particularly in the area of HIV treatment and prevention. I currently lead a number of NIH-funded studies, including studies of peer-support interventions to improve medication adherence among youth and adult persons living with HIV and PrEP uptake among HIV-negative transgender and non-binary youth. I also lead studies to examine different PrEP dosing options for sexual minority young adults. In addition to my research activities, I have instructed an undergraduate course in human sexuality and a PhD-level course in grant writing and behavioral medicine interventions.
Dr. Horvath is accepting applicants for Fall 2024 admission to the SDSU/UC San Diego Joint Doctoral Program in Clinical Psychology. Please visit the JDP website for more information about the program.
