BIO
Karli Hochstatter is an epidemiologist and health services researcher focused on the intersecting epidemics of substance use disorders, infectious diseases, and criminal justice involvement. Her research focuses on developing innovative strategies to monitor and prevent drug overdose among people with opioid use disorder, and to increase utilization and retention in effective prevention and treatment services. She is currently leading several projects in collaboration with the New York City Office of Chief Medical Examiner that aim to develop advanced data science techniques for improved overdose mortality surveillance and translating these findings into prevention intervention science by delivering timely services to overdose decedents’ social network members encountered during death investigations. She is also leading projects in other jurisdictions to understand how medical examiners and death investigation teams can aid in improving overdose mortality surveillance and overdose prevention and linkage-to-care efforts. Other current projects include examining the impact of changing methadone treatment practices and characterizing adulteration patterns in street drug markets. In addition to her doctoral training, Dr. Hochstatter completed a postdoctoral fellowship at Columbia University (T32DA037801), is a scholar of the Criminal Justice Training Program at Brown University (R25DA037190), and has active appointments with Columbia University’s Social Intervention Group and the University of Wisconsin Madison’s Department of Medicine.
