Julie Parsonnet

Julie Parsonnet is the George DeForest Barnett Professor of Medicine and Professor of Epidemiology and Population Health at Stanford University School of Medicine. She leads the Parsonnet Laboratory, focusing on infectious agents' role in chronic diseases and serves in the Division of Infectious Diseases and Geographic Medicine and Maternal & Child Health Research Institute.

• Medical Degrees: MD (Cornell, 1983), AB (Harvard, 1979)
• Board Certifications: Internal Medicine (1986), Infectious Diseases (1988)

Her research spans three decades, pioneering H. pylori's role in gastric cancers and expanding to infection-metabolism connections. Recent work includes human temperature decline as infectious disease marker and wastewater surveillance for community-level virus tracking (HIV, RSV, SARS-CoV-2). She investigates microbiome development in infants and antimicrobial chemical effects.

Her 2024-2023 publications reveal trends in environmental virology, pediatric growth modeling, and firearms injury epidemiology. Notably, she demonstrated wastewater solids' superiority in HIV detection and RSV season tracking through 176 US sites.

• Scientific Recognition: NAM Member (2019), AAP Member (2017), ASCI Member, IDSA Fellow
• Leadership: NIH MID-B Study Section (2011-16), Thrasher Foundation SAB (2006-11), SAFE President

As principal investigator, she mentors graduate students and leads NIH-funded clinical trials including STORK cohort (microbial exposures in children), Triclosan Microbiota Study, and SARS-CoV-2 Dialysis Screening. Her lab's interdisciplinary approach combines epidemiology with computational biology to address global health challenges.
