About Me

Douglas Walker, PhD, joined the Department of Environmental Medicine and Public Health as an Assistant Professor. He received his BS in 2009 from the University of Massachusetts-Dartmouth and completed his PhD in 2017 from Tufts University in Environmental and Water Resources Engineering.

During his postdoctoral fellowship at Emory University, he acted as Director of Exposome Research for the Clinical Biomarkers Laboratory and was a member of the HERCULES Exposome Research Center. Through application of high-resolution mass spectrometry platforms, Dr. Walker has shown it is possible to provide measures of 10,000-100,000 chemical signals in a cost-effective manner using a single human blood sample, providing a key advance for nutritional assessment, precision medicine and exposome research. At Mount Sinai, his research will be focus on continued development and application of advanced analytical strategies for measuring the occurrence, distribution and magnitude of previously unidentified environmental exposures and assist in delineating the mechanisms underlying environment-related diseases in humans.
