Dr. Jacky M. Jennings is an associate professor of pediatrics at the Johns Hopkins University School of Medicine with a joint appointment in the department of epidemiology at the Bloomberg School of Public Health. 

She serves as director of the Center for Child and Community Health Research and associate director of General Pediatrics and Adolescent Medicine. She also co-directs a National Institute of Allergy and Infectious Diseases -funded predoctoral training grant and is co-chair of the Johns Hopkins Bayview Scientific Advisory Board.

Dr. Jennings’ research focuses on the social epidemiology of sexually transmitted infections. She has established national prominence and leadership as an epidemiologist with a focus on improving the health of children, adolescents, and young adults—particularly those that reside in urban, disadvantaged communities.

She earned her master of public health and her Ph.D. from the Johns Hopkins Bloomberg School of Public Health.

Dr. Jennings is on the board of trustees of the International Society for STD Research. She teaches a course to graduate public health students on how to investigate public health, and she mentors students from the undergraduate to post-graduate level. more

Research & Publications

Research Summary

Dr. Jennings’ primary research contributions are in the area of sexually transmitted infection (STI) and HIV transmission dynamics with a specific interest in determining the mechanisms through which place plays a role in local transmission dynamics causing endemic rates of STIs and HIV. Secondarily, she has begun to make significant research contributions in the application of epidemiologic principles to the translation of research questions in pediatrics. 

Dr. Jennings is the principal investigator on a five-year Career Development Award (K01) from the National Institute on Drug Abuse. The primary goal of the K01 is to determine whether and the extent to which drug markets explain the association between structural factors of neighborhoods and risks for STIs among urban, disadvantaged youth.  

She collaborates closely with the Baltimore City Health Department and is the lead on an initiative funded by the Centers for Disease Control to decrease HIV transmission in Baltimore City through the identification of high HIV transmission areas. The project will involve enhancing screening and testing in identified areas as well as public health detailing to primary care providers. 

Dr. Jennings also leads a large-scale evaluation of evidence-based programs designed to reduce teen pregnancy and negative reproductive outcomes in the State of New Jersey. 

Dr. Jennings collaborates with colleagues within and outside the Division on a wide array of health outcomes including pelvic inflammatory disease, pediatric obesity, intimate partner violence, cardiology and sickle cell disease.  She also teaches and advises graduate public health and medical school students.
