Biography
Dr. Shrestha is an Assistant Professor Adjunct at the Yale School of Medicine’s AIDS program. He is the Principal Investigator on the National Institute of Health funded K01 (NIDA: K01DA051346), R21 (NIDA: R21DA051934), and R21/R33 (FIC: R21TW011665) awards. 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. His current work focuses on reducing the HIV epidemic that disproportionately affects socioeconomically disadvantaged (i.e., drug users) and sexual minority group (i.e., men who have sex with men) using mHealth technologies as an innovative platform to scale-up prevention efforts.
