WashU Mass Spec MTAC@MGI provides consultation and direction to investigators and collaborators wishing to incorporate mass spectrometry-based -omics into their research projects.

Young Ah Goo, PhD

Meet the Director

Young Ah Goo's research focuses on the use of mass spectrometry-based "omics" applications to answer biological questions, with a particular emphasis on discovering diagnostic and prognostic biomarkers and therapeutic targets for human diseases. Throughout her career, Young Ah has directed Mass Spectrometry Centers at Northwestern University, University of Maryland, and University of Washington. As the Director of MTAC, she leads a fast-paced, highly collaborative, and high-throughput center that provides mass spectrometry support for proteomics, metabolomics, lipidomics, and mass spectrometry imaging to collaborators around the world.

Meet our Collaborators

The WashU Mass Spec MTAC Collaborators at Washington University are a dynamic group of physicians and scientists who leverage the power of mass spectrometry-based "omics" to advance their understanding of the world around us. Despite not necessarily having a mass spectrometer in their own research group, they are well-versed in the language of MS-based omics and utilize this tool to drive cutting-edge research."
