Dr. Ju Nyeong Park is an epidemiologist with nine years of experience in conducting research on substance use, trauma, HIV and HCV among under-served populations. Dr. Park has expertise in the design and implementation of epidemiological studies both domestically and internationally, as well as skills in data analysis, survey and scale development, and data management. Dr. Park directed the FORECAST study, a multi-phase study examining the feasibility of drug checking as a public health tool to address the fentanyl overdose epidemic. Dr. Park is currently collaborating on a pilot study evaluating the impact of a brief fentanyl test strip intervention among female sex workers (FSW) who use opioids. She is also working on an NIH-funded study examining the HIV risk environment of street-based sex workers in Baltimore, Maryland, and a SAMHSA-funded project that is expanding drug treatment, mental health services, and linkage to community-based care at the Bartlett Clinic at the Johns Hopkins Hospital. She has conducted program evaluations and needs assessments for a variety of health agencies, including the Baltimore City Health Department, the Maryland Department of Health, and the World Health Organization.
