Lauren M Petrick, PhD

Lauren Petrick, PhD, is a Professor of Environmental Medicine and Head of Untargeted Metabolomics at the Senator Frank R. Lautenberg Environmental Health Sciences Laboratory at the Icahn School of Medicine at Mount Sinai. Dr. Petrick is an analytical chemist with advanced training in metabolomics and exposomics. Her research focuses on developing untargeted exposomics methodologies for environmental health studies, leveraging high-resolution mass spectrometry (HRMS) and advanced biostatistics and bioinformatics.

In addition to traditional analyses of urine, plasma, and serum in large cohort studies, Dr. Petrick’s current work emphasizes minimally invasive sampling approaches—such as dried blood spots, capillary blood microsamplers, and wearable wristbands—that can be collected at home and mailed in. These approaches enable accelerated recruitment and retention in large-scale clinical and epidemiological studies, particularly among sensitive or hard-to-reach populations.

By capturing environmental exposures (e.g., pesticides, PFAS, personal care products, tobacco) and biological response markers (e.g., fatty acids, bile acids, lipid mediators) in a single assay, her untargeted workflows enable early disease detection, targeted prevention strategies, and personalized health monitoring.
