Giehae Choi

Giehae Choi, PhD, MPH, is an Assistant Professor at the Johns Hopkins Bloomberg School of Public Health, with primary affiliation in the Department of Environmental Health and Engineering and joint affiliation in Epidemiology. She is also a key investigator in the Environmental Influences on Child Health Outcomes (ECHO) Data Analysis Center, where she contributes to large-scale research on children's environmental health. Her work bridges environmental exposure science and public health policy, focusing on vulnerable life stages such as pregnancy and early childhood.

Education:

• PhD, University of North Carolina at Chapel Hill, 2020
• MPH, not specified in text

Dr. Choi's research centers on environmental epidemiology, particularly reproductive, perinatal, and pediatric epidemiology. Her work investigates the health impacts of chemical exposures—including PFAS, metals, phthalates, and organophosphate esters—on neurodevelopmental outcomes in children. She employs advanced statistical methods to analyze complex cohort data and simulate public health interventions. Her research also explores the modifying role of nutrition in chemical toxicity, aiming to inform prevention strategies.

The recent trend in her publications reveals a strong emphasis on prenatal environmental exposures and child neurodevelopment. Her studies frequently use data from the Boston Birth Cohort and the Norwegian Mother, Father and Child Cohort Study (MoBa), applying mixture analysis and epigenetic methods to understand multifactorial risks. Topics include ADHD, executive function, fetal growth, and DNA methylation, all within the broader context of environmental justice and policy translation.

Scientific Awards:

• SER Lilienfeld Postdoctoral Prize Paper Award (2023)
• SER Annual Meeting Best Poster Award (2021)
• NIEHS Extramural Paper of the Month (May 2021)
• NIEHS Extramural Paper of the Year (2021)

Dr. Choi leads an NIH-funded K99/R00 project on maternal chemical exposures and offspring neurodevelopment, with a focus on nutritional modifiers and intervention simulation. She collaborates extensively across institutions and is involved in major consortia such as ECHO. While specific advisees are not listed, her role as a principal investigator suggests mentorship of graduate students and postdoctoral researchers. She is embedded in research teams analyzing metabolomic, epigenetic, and behavioral data to uncover environmental determinants of child health.
