Dr. Lesko received her Master of Public Health in 2006 from Emory University and then spent five years working in governmental public health, at both a local and state level, before returning to get her Doctoral degree from the University of North Carolina in 2015. She has been on the faculty of Johns Hopkins University since 2015. 

Dr. Lesko's research interests include: the application and development of epidemiologic methods and theory for causal inference and generalizability; describing and improving clinical outcomes for persons with HIV living in the United States, particularly as they relate to mental health, alcohol use and substance use; and monitoring and improving progress through the HIV care continuum.
