Prior to pursuing graduate training, Dr. Roth worked for nearly 10 years as a public health practitioner.

Her MPH in international health and development is from Tulane University. She received a PhD in health behavior from Indiana University and then went on to complete a postdoctoral fellowship in substance use and infectious diseases at University of California, San Diego.

Dr. Roth’s research is focused on understanding how individual, social, and environmental factors influence health disparities. In particular, she is interested in the intersection of gender and drug use on women’s health and the use of novel interventions to prevent opioid-related overdoses and increase access to health care among people who use drugs.

The goal of Dr. Roth’s work is to co-create sustainable solutions to public health problems by working in partnership with community members and advocates. To this end, Dr. Roth initiated the health equity advancement lab (HEAL) in 2018. Please check out the HEAL website for current projects and opportunities.
