Dr. Roth worked in a variety of community-based organizations prior to embarking on her graduate training. Across these positions, she worked to link individuals to sexually transmitted infection (STI) and HIV testing, medical care, and social services to decrease their likelihood of acquiring/transmitting communicable diseases. She pursued a Ph.D. to address how individual, dyadic, and neighborhood-level factors contribute to health disparities. Over time, she became increasingly interested in “mHealth research” as a mechanism for measuring event-level behavioral phenomenon and capturing information about high- and low-risk activity spaces. She completed a Predoctoral Research Fellowship sponsored by the Indiana University-Purdue University Indianapolis Center for Urban Health to use smartphone-delivered digital diaries to measure how situational factors (e.g., drug craving; mood; relationship to sexual partner; day, time, or location of sex) impact HIV risk among women engaging in transactional sex. In 2012, Dr. Roth began an NIDA-funded postdoctoral fellowship (T32 DA 023356) in the Division of Global Public Health at the University of California, San Diego (UCSD). At UCSD, her interest in mHealth research intensified as she began to consider how drug use impacts adherence to antiretroviral treatment among persons who inject illicit drugs. In September 2014, she joins the Department of Community Health and Prevention at Drexel University as Assistant Professor. In Philadelphia, she will utilize a community-engaged research approach to design and evaluate intervention studies for STIs, HIV, and drug abuse-related disparities.
