Mark Lowenthal

Dr. Mark Lowenthal began working at NIST in 2007 following a post-doctoral position at the University of Colorado Health Sciences Center and a research fellowship at the National Cancer Institute (NCI/NIH). Mark received a Ph.D. from the University of Maryland in analytical/physical chemistry and a B.S. from James Madison University.

His research activities at NIST include the measurement of proteins, metabolites, amino acids, lipids, and sugars in various biomaterials.  He has helped develop new methods for quantification of troponin I in serum, an important protein marker of cardiac muscle injury using immunoaffinity techniques and mass spectrometry. Quantitation of targeted biomolecules has led to the production and certification of several NIST Standard Reference Materials. Other research applications include mass spectrometry-related measurements of proteins associated with neurodegenerative disorders, characterization of antibody function on nanoparticles, and detection of microbial virulence.  Mark has co-authored more than 25 peer-reviewed publications and two book chapters.
