His research has largely centered on enhancing the design, delivery, and placement of interventions that integrates evidence-based behavioral approach, biomedical components, and innovative use of mHealth strategies, aimed at improving health outcomes and the quality of life of underserved populations. Specifically, he is interested in syndemics of health issues that have profound implications for access to and utilization of healthcare services and overall HIV prevention efforts in a range of settings, including community and healthcare, addiction treatment, and criminal justice settings, both domestically and internationally.
